Hello, Well... You can take the lamp out of the suspect line up even though you have no image the lamp should still be good. (to make sure take lamp out and give it a thorough inspection, check for brown marks, white dots, cracks in the lense. After you made sure about the lamp. Find out if the buzz...

I found this video, It's not for your particular model but the procedure is the same.

I hope this can be of help.

darkart77

Totally agree with ribowman

darkart77

In these type of scenario the best advice I can think of is to make sure you get the parts from a reliable source that offers a warranty and some technical advice to guide you through it.
Perhaps discount-merchant.com, They are one of my vendors.

darkart77

Unfortunately they don't make these type of bulbs.

darkart77

The color wheel's symptoms are usually a mechanical humming noise, a scritching loud noise. the image can also turn back and white and then there can be other symptoms.
The color wheel itself can be undamaged and the air barring can be rotating the wheel at the wrong RPM.

darkart77

Im leaning 90% toward the ballast.

darkart77

post the full model for your tv and I'll guide you to the lamp you need and give you some additional info on it.

darkart77

the ballast can range anywhere from $200.00 new from Samsung. Or try stores like Discount-merchant.com, partstore.com etc...
this replacement can also be done with out the repair guy's over charges.

darkart77

the thing with the ballast is that it will cost you more to have tested than to replace it. Keep in mind that it is a consumable part
so....Im leaning for the ballast.

darkart77

please lost the model and manufacturing year of your tv.

darkart77

this is a common symptom cause by the chips on the DMD board.

darkart77

The lines are a common and frequent sign of the DMD board. Place an advanced search to see other people's solution and problems. Just enter as key word vertical lines.

darkart77

First thing is to check the lamp to see if it's been burned out. Depending on the result most of the time just replacing the lamp will take care of it. Some times the ballast will need replacing. The turn on over and over is due to the ballast not able to transmit voltage to the lamp. But if the lam...

darkart77

Fixing your DLP, will be more cost affective, Specially if you have to just replace the lamp or ballast board. They can both be replaced at home "easy fix" If you have a chance...the guys at discount-merchant.com will offer you free technical trouble shooting and even guide you through the...

darkart77

If the color when you bought is used then you may have a problem with that. The RPM speed variates with the color wheels. barring can also be different.

darkart77

Hello,
Your tv does have a lamp that normally has be replaced after about 8000 hrs. That's if you have a Philips lamp. "most mayor tv brand carie it"
The guys at discount-merchant.com do free trouble shooting and they have the lamp available.

darkart77

That can potentially be the ballast board, "it powers up your lamp"
Unfortunately samsung, has a very bad rep for defective ballast boards.

darkart77

Unfortunately it is possible to be the bulb however Samsung, does have a bad reputation for having defective ballast boards "ballast powers up your lamp" it is a consumable part on your DLP. Check the lamp for damage.

darkart77

Most of the time it just the lamp. Take your lamp out and check it for physical damage.

darkart77

Unfortunately the screen is a part that most places like Discount-merchant.com, partsore.com etc... they won't Carrie it. Price won't go down much. I'd keep checking on e-bay or somewhere like that.
Best of luck.

darkart77

if the projection wega you have there is DLP. the problem is more than likely due to a faulty color wheel.
It can easily be replaced. Not very expensive.

darkart77

It's very likely to be the ballast board not sending enough voltage to the lamp.

darkart77

well it can be the ballast board not sending the right voltage to your lamp, also...are you sure you reset the lamp timer correctly, cleared the hours back to "0" besides that well... If you bought a generic lamp, you may be subject to a faulty picture. depending on your tv brand, most tvs...

darkart77

I see that your tv takes a LiFi lamp. Only the manufacturer would be able to supply it. Most online stores show different lamps so be careful and search for the right lamp.
Good luck.
I believe that the LIFI sets are 1080p LCD Rear Projection models with the high intensity bulbs

It also sounds like you have a case of a collapsed light tunnel, to find out more check this link. viewtopic.php?f=21&t=1353 dose it appear in the component cables & HDMI? Try to bring up the TV menu, see if the vertical gray line also affects it. If so then it’s a defective DMD board. if yo...

darkart77

No problem. If you have a minute just go to www.youtube.com and place this search. samsung lamp replacement. A video will come up. Good luck.

darkart77

It is very probable that you have a bad color wheel. The actual barring can be decalibrated by regular usage.

darkart77

with out the model make or tv's age it will be hard to even try a diagnose. Please post another inquiry with more specific symptoms and other repairs.

darkart77

I would say you're on the right track, the only part in your that would produce that noise in your tv is the color wheel.

darkart77

most of the time this problem occurs when the ballast board is not sending the right voltage to the lamp.

darkart77

This is the most common and normal symptom when the lamp is going out.
I'd say you'll be needing a lamp soon. Make sure it is Philips lamp. That's the original lamp replacement.

darkart77

I found this link that has a very similar issue I hope after reading it you find it helpfull.

viewtopic.php?f=21&t=1373&p=4730&hilit=moving+picture#p4730

darkart77

Well... unfortunately Samsung, does have a bad rep when it comes to their ballast boards. If the lamp is igniting "it's a good working lamp" the ballast can run you only about 80-90 dollars at discount-merchant.com. fairly easy to replace at home.

darkart77

check the ballast and lamp connectors just to make sure. If the ballast you bought was used it's possible that it is defective. Resetting the lamp timer might help. Other than that it can potentially be the power supply board not filtering the voltage going to your ballast properly. Not likely but p...

darkart77

It's very possible that you have a power supply problem. Nothing seems to respond, typically the source can start there at the power supply board. Then again with out the tvs model number, age previous repairs it's hard to tell. Post another inquiry and note all the symptoms along with the model and...

darkart77

f you are installing this FAB Bearing (SILVER) Colorwheel + Housing, in place of your FDB Bearing (GOLD) Colorwheel you will need to REMOVE a jumper ("OPEN") on the DMD Board (Jumper CN810). This jumper is on the BACK SIDE of the DMD Board (usually covered by an aluminum panel--you do not ...

darkart77

HI, I checked the tv model you have there and the symptom is very common, ( color wheel ) this part is fairly inexpensive and it can be replaced with out calling the repair guy.

darkart77

this is a frequent symptom from the DMD board chip. It more than likely is that.

darkart77

There can be multiple reasons for picture failure. Have you had any problems before and how did you fix it. On your next post please describe the symptoms.

darkart77

Normally the DMD board causes this type of symptom.

darkart77

the lamp flashing symptom can also be caused by the ballast board not sending the correct voltage. There are sensors that detect for example, color wheel malfunctions, ballast, power supply etc...

darkart77

this is normally caused by the ballast board not sending the right voltage.

darkart77

First, the lamp has nothing to do with this particular problem. Lamp's job is simply to reflect white light.
However to let you know what could be causing the problem, please post the complete model number for your tv.
Most of the time this symptom is the DMD, board.

darkart77

Check your lamp timer and make sure the hours have been cleared back to 0. Other than that check the connectors and make sure they are connected all the way in.

darkart77

light tunnel issue. Maybe. But Im leaning toward the Bering, if it doesn't allow the correct RPM. speed the tv simply detects a malfunction and most likely that is the reason for the symptom.

darkart77

I have seen this exact problem numerous times and in my experience, I'd agree with you. DMD board/chip

darkart77

Thank you for the link. That is helpful.

darkart77

check all the settings for your color and contrast brightness and all that. The default settings.
