wbraun, What is the model on your TV? If your TV is an LED projection, then it's a different story... There is no Lamp or Color Wheel, instead it uses a 3 Phlatlight system from Delta Electronics. The LED's do fail, but not all of them and it is not easy to replace. It is similar to the 3 LCD engine...

avionicspro, There is no way to really test the color wheel for power. Here is how the TV powers on: PS Power unit to system standby --> Power button is pressed --> Check for Lamp Cover Door Switch -> Signal is sent to power on -> ColorWheel Spins (If proper connection / rpm is detected) -> Sends si...

erkuas, The problem you are describing is 90% chance your color wheel! Do not attempt to turn on the TV any more as you may damage other components within your TV. Look here: http://guides.fixyourdlp.com/samsung/bp96-01579a.php This a good guide on what your color wheel is and how to replace it. The...

Jerryus,
When was the last time you replaced the lamp on the TV? What sound are you talking about happing 10 times? Is it a click noise? Is it a whining noise? Noises are good, it helps us diagnose further!

Give us some more information... What model is your TV?

ovadoggvo

DaveC, The noise you are referring to on startup is most likely caused by a failing Digital Board or a weak Power Supply. I think that the problem is caused by insufficient power or a cold solder on the SMGP (surface mount graphic processor) on the digital board. Once the TV warms up, the current ru...

Eze311, Recheck the ballast voltage. You shouldn't here a click noise if there is 0.0V going to the ballast. How are you testing the ballast? You need to remove the back cover of the TV, but use some tape to press the lamp cover door sensor down. Then test the ballast voltage when you press the powe...

ovadoggvo

avionicspro, The colorwheel may not be bad, but it does seem like the cw sensor board is.. It comes on the color wheel housing. I would order a new wheel and then troubleshoot further. Your ballast is good, your power supply is good (since you can force on the ballast).. You are not getting 5vdc fro...

I would recommend entering the service menu and doing a factory reset. To get to the service menu:

Power OFF your TV

On the remote control press: Mute, 1, 8, 2, POWER

The TV should turn on into the service menu.

Do a factory reset and it may resolve the issue.

ovadoggvo

Let us know how it goes. Your next step would be to FORCE ON your ballast to see if it actually works. I have a post here somewhere with that information.

ovadoggvo

David, The DMD board, digital board, and analog board are responsible for the video throughput of your TV. Your Powersupply, AUX power supply, and ballast are responsible for the current going through your TV. The light engines from D-M are cheap and they work great. I kinda regret leting people kno...

ovadoggvo

egates, I would be careful measuring the voltage to the bulb. You may burn your Multimeter. The spark voltage on these lamps is 15Kv, thats 15,000V. The running voltage is anywhere between 60V to 150V (depending on the life of the lamp). If the FORCE ON is not powering the ballast, then there is pro...

ovadoggvo

Rick, I would check Discount-Merchant.com or PartStore... If D-M has it, you will get the same thing but cheaper. DrDragon, I'm glad we could help you get your set up and running! I would also read my post here about what OSRAM/Generic can do for you: http://fixyourdlp.com/forum/viewtopic.php?f=10&a...

ovadoggvo

Pat, Let us know what happens. I'm willing to bet that the lamp is good, but being sure is worth the $20. The lamp door switch is not available from samsung for some reason, but our buddies at D-M have it here: http://www.discount-merchant.com/We-provide-factory-original-parts-worldwide-p/1088852-sa...

ovadoggvo

noonej21, Why am I not suprised? This is the EXACT reason I ALWAYS recommend Discount-Merchant for any lamps related to ANY brand TV or Projector... People go out and try to save a few bux by buying out on ebay or some guy with a nice website shipping from his house! BE CAREFUL... As noonej21 just e...

AnnyongBluth, The freezing is normally caused by a defective DMD board... The Digital Board is also a possibility, however, in the scenario that you are describing... the DMD board is most likely the issue. When a DMD is failing you will get the following: Freezing of picture Distortion of picture /...

ovadoggvo

Joec999,
My best guess would be a defective digital board. Read the following post to read my explanation:

viewtopic.php?f=10&t=166

Also, I would check discount-merchant.com for the parts... They are the only ones that would have it at a decent price.

ovadoggvo

eyerish87, I would have to say that the Digital Board is the issue. The digital boards DNIe chip handles all digital processing of the video before it hits the DMD board. The video inputs you are describing are all getting processed by the DNIe, the PIP is never getting digitally enhanced and neithe...

ovadoggvo

tymtrvlr, The power button being pressed when you plug the TV in does not do anything at all... The symptom you have is the result of a bad Digital Board (60%) or DMD Board (40%). Your model is notorious for a bad digital board. I see more of this on a daily basis. The digital board pretty much cont...

ovadoggvo

David, The problem you are describing seems to me to be a bad DMD board. The picture freezing then blacking out are normal signs of a bad DMD board. I would return that ballast because I don't think it will do you any good. Check Discount-Merchant.com to see if they have your DMD or even you light e...

I'm there champa... I'm trying to get to everyones posts guys. Bear with me.. I'm spending more time on this forum than any other just because of the huge demand here. Please do your due diligence of researching and taking the basic diagnositc steps before posting. The more information you give me a...

ovadoggvo

champa, Make sure you have your color wheel in properly. The cable could be backwards! One of the CW cables can be inserted backwards without realizing it. Also, make sure you cleaned the particles of the broken color wheel completely. Next, check to see if you are getting ~350-380V to the ballast f...

ovadoggvo

Pat, I beleive D-M has a lamp testing fee of $20.. I would excersize that option to see if the lamp is indeed bad. Philips bulbs are very very very very rarely defective, so it may be a waste of $20... but at times a bad ballast may have damaged even a new bulb. Too bad for D-M if this happens but g...

ovadoggvo

wbraun, I would try a new HDMI cable (make sure it's the latest version)... Many people don't know but HDMI has multiple versions and older samsung TV's are really picky about the version of the cable and component being hooked up (they must match).. You have the HLT series TV and it should be able ...

Our service center orders from them 3-4 times a week. All of our DLP lamps come from them and so do nearly all the parts. I assume we get very special pricing from them. I personally have ordred quite a bit of parts from them as well for repairs I do on my off time. I don't know what the price break...

gr00veth3ory, Make sure you all the screws of the back panel of your TV removed, it should fall right off. look at this ballast repacement guide to get an idea of what you are working with: http://guides.fixyourdlp.com/samsung/bp47-00033a.php Also, the problem you are describing seems to be caused b...

ovadoggvo

prowler3, The problem you have seems to me to be the color wheel (80% sure). There are only 3 moving parts inside your TV set that can make that noise.. Fan #1, Fan #2 (lamp cooling fan), and your Color wheel. The chances of the Color Wheel failing is 5X more than any other moving part. i would reco...

ovadoggvo

noonej21, The ballast may be bad or failing or it may be that you bought a GENERIC lamp. Does the lamp say Philips on it? Did you buy it from an authorized Philips distributor. I would be very careful where you buy the lamp because some of these lamp dealers see it as a disposable part and nobody is...

ovadoggvo

How about the color wheel speed sensor board? Did you see any physical heat damage to it?

If not, DMD or Digital Board could be the issue

ovadoggvo

Sh*t mike... You seem to be having a hell of a time with that TV. The only other thing that I could think of that the TV has is the AUX Power found here: http://www.discount-merchant.com/We-provide-factory-original-parts-worldwide-p/1069093-samsung.htm I don't know what else it might be.. Did you ch...

McGuire0010, The problem you are describing is a very common one among Samsung DLP sets. The issue is the result of a collapsing light tunnel. The dark bar will start to get bigger and bigger as time goes by. Pretty much the light tunnel looks like this [] and it is starting to collapse is looking l...

Drew, I'm glad you're taking action. This is why I was so excited about the parts on D-M that I started posting everywhere about them... Now I kinda regret it because I am having trouble finding parts that I myself need in stock. But I'm glad I could help people out so I guess it's a sacrifice I had...

ovadoggvo

Drew,
Those are both the same, I dont' kwow why the price is so different. Either one will work.

ovadoggvo

eyerish87,
A few questions to diagnose further:

Do the lines apear on on the menu screen? or are they under the menu screen?

Do you have the same problem with PIP?

Does your VGA input work ok?

What about component?

What about standard video in?

Let us know.

ovadoggvo

DrDragon, Try taking out the color wheel cable and inserting it the other way. See if it makes a difference. You will not damage the set if you do this. I am not watching you work but I've had so much experience with these TV sets that I pratically have the damn things memorized to a T. I was re-rea...

tripleb52, The boards tend to fail with time. The main reason this board fails is due to the overheating of the DNIe chip. The chip is respnsible for decoding and encoding digital signals using Samsung DNIe technology. Great technology, great TV's from the get go, but as time goes by they need a lit...

ovadoggvo

bitmage, The Analog board is most likely the issue there. It is a comonly failing part, right next to the Digital board, and DMD board. D-M.com is the only place where you can expect to get one at a reasonable place. PartStore and Samsung Parts want an arm and a leg for the board. Let us know how it...

ovadoggvo

egates, The flashing light on the ballast is the ballast grounding out because it can't power the lamp. If you hear a constant clicking and that light keeps flashing, this means that your ballast is most likely bad. In a situation like this, you would hear 3-5 clicks, then a pause, then another cycl...

ovadoggvo

coachmike,
Hmm.. I would guess DMD board or Digital board... It could go either way. If it's turning it self on and off, then a faulty digital board could be more likely. The digital board does control the menu and remote functions to an extent.

Let us know how it goes!

ovadoggvo

a42kracer, Does your menu system also get discolored? Is your Picture in Picture also affected? If you answer yes, DMD board is most likely the issue.. Discount-Merchant has them for CHEAP and their prices make it definately worth fixing. If you answer no, the Digital Board is most likely the issue....

ovadoggvo

musowl, I hate intermittent issues with no clear signs! Since coachmike has a similar issue we can wait to see if the power supply fixes his issue. If not, the problem can be the Digital Board or the DMD board. It's very difficult to tell and this is when the Samsung service reps start replacing boa...

ovadoggvo

stuart, You may have damaged the temp sensor when you opened up your TV. It's a slight possibility that the Temp Sensor is bad. I think D-M sells them for around $20. It's worth a try. Next guess would be DMD board just because in your first post you said that the TV would not turn off unless unplug...

ovadoggvo

Drew, First step for you would be to pick up a Digital Board from D-M to see if that resolves the issue. It may also be the analog board but the digital board carries the DNIe chip.. All your analog and digital signals go through the digital board and are converted to digital before produced onto th...

ovadoggvo

Hookup2, The problem you are describing is called the infamous "Black Out" issue. This problem is usually caused by a bad DMD board. DMD board is $700 from samsung but Discount-Merchant sells them for $180-$250... I recommend buying the complete light engine if they have it as the price di...

ovadoggvo

dre17, The problem you are describing may be 1 of 2 problems. 1 - Color wheel - Reason: The color wheel may have a bad bearing, which in turn is causing the TV to shut down or disrupt the functionality of the DMD board. I would open the set and check the color wheel for issues. A good guide can be f...

ovadoggvo

cdwaters, The DNIe chip is what is failing and the problems may arise intermittently. I would recommend replacing the board while they have it in stock. The reason that there are 2 different boards for your set is because there are 2 different chasis models. L62A is the chassis number... You can fin...

ovadoggvo

DrDragon, No smoke is a good thing. Make sure you installed the flex cable of the color wheel the right way. Your model is a tricky one one the cable will go into the connector either way! Lot's of people install the cable backwords. Also, make sure you lamp door cover is on and your TV is back toge...

ovadoggvo

I'm glad I could help. Let us know if there is anything else we can do for you.

ovadoggvo

cdwatters, The problem you have with your TV seems to me to be an issue with the Digital Board, however, a defective DMD board is also a possibility. The reason behind this is due to the fact that the Digital Board processes digital signals unless the TV is upconverting everything to HD or processin...
