CapeCodDon, The issue is definitely the color wheel. It will not cause color issues until the wheel actually starts to vary in speed. The whining is the begining... The color issues will come later or intermittently. If you replace the wheel, you will get much less noise coming out of your TV and yo...

CapeCodDon, Did the strobing and lines on the screen also affect the menu overlay? Or were they behind the menu? If the strobing was behind the menu, then the problem is most likely the Digital Board. If the Menu was affected, then the problem is most likely the DMD Board or Color Wheel. If the colo...

Wow! Must have been a Philips. I don't know any other manufacturer that can make a lamp that reliable. 14,000+ hours is amazing!

ovadoggvo

KDB, I would assume you have a bad ballast if your old lamp lights, but the new one doesn't. A weak ballast can cause this to happen. When the mercury level in the gas chamber of the lamp gets lower, the lamp becomes easier to spark on. Although it lights up, the picture will be significantly dimmer...

Denbo,
Great! I'm glad you got the thing going with a digital board!

I would prefer to keep Samsung posts in this thread so I'm not all over the place. If anyone else still needs help, please post here.

Drew, The problem is the DIGITAL BOARD.. All of your digital inputs are defective. The VGA input is actually an ANALOG signal that goes straight to the DMD board without Decoding by the DNIe chip. Your component, svideo, rca, and hdmi will all pass through the digital boards upconversion DNIe chip t...

Guys, Sorry I've been out of the loop for a little while. Been busy doing other things rather than helping people fix their TV's! But I just heard of a NEWS FLASH for JUN15 2010. There is a class action lawsuit that passed for those people on this forum that have an HL-P series, HL-R series, HL-S se...

Harry, What do you mean by you were fixing your light tunnel? If the mirrors are not exactly aligned properly then you will have color issues!

AkaiDLP, I suggest buying a new lamp for your TV set to start off the diagnosis. After 3 Years, the lamp is due for replacement anyway. You will not be able to diagnose properly with a 3-year-old lamp! Your replacement lamp can be found here: http://www.discount-merchant.com/p-95-samsung-bp96-01472a...

I suggest reading this post I made on the Sony Rear Projection TV with Green or Blue blob problem:

Good luck.

Jemtech, To me it seems like your Y-Sustain board(most likely) or X-Sustain board are starting to fail.. Read this post here: http://www.fixyourdlp.com/forum/viewtopic.php?f=6&t=241 And then the red dot post I have here: http://www.fixyourdlp.com/forum/viewtopic.php?f=6&t=868 I think the 2nd...

Harvey, What do you mean by flickering picture? I'm not understanding... Is it red dot's on the screen? Is the screen shutting off and on? Red Dots can be caused by improper voltage going to the plasma panel by the X and/or Y Sustain boards. These boards normally have potameters to adust the voltage...

irefrem, I don't find it feasible to replace components on these boards. I would recommend purchasing a test working unit from an reputable parts dealer.

ovadoggvo

Morales, This is a very common among these TV sets. The problem is most likely the Y-Sustain board. I would check the power going into the Y-SUS and make sure it's around 190VDC with the Y-SUS DISCONNECTED... Then with the X-SUS disconnected check for 190VDC + 60VDC out to X-SUS from Y-SUS. If the v...

I have seen many posts about this problem around the internet and I thought I would shed some light on the situation...

Guy's, A little bit of a background on these Sony LCD Projection XBR Series TV's.

This class action lawsuit was similar to the one posted against Microsoft and the XBox 360 unit....

Dusty80, Sounds like you've been reading my posts... Good job on making an excellent diagnosis yourself.

musicmanboy, Ok.. First of all, I recommend reading this post: http://www.fixyourdlp.com/forum/viewtopic.php?f=10&t=19 It should have given you some insight. Now, I will tell you the basic things to do in order to take a better guess on which board is failing: 1 - When the TV is on and color sta...

ovadoggvo

Jake, My guess would also be the Analog board. Do me a favor... Connect your laptop or computer to the TV set using VGA cables and leave it on for a few hours and tell me if you experience any problems. This check will tell you if your DMD board is good or bad. The VGA input is DIRECT TO DMD on thes...

ovadoggvo

WAPG2385, Great! I'm glad it fixed the problem and my 2nd hunch was wrong! The melt down of the cable was probably what was causing the funky affect being displayed by the DMD board. Which cable was the charred one? One cable goes to the actual color wheel motor and the other cable connects to the &...

ovadoggvo

54321, It seems like you did your homework! I'm pretty sure the the humming problem you're having will be resolved by the color wheel. As a recommendation, take a look at the color wheel guides posted on http://guides.fixyourdlp.com ... I recommend a lot of people to that very exact page because of ...

ovadoggvo

WillGolfForFood,
In your situation, it seems like DMD board is most likely at fault. If you are getting illumination on the screen but the screen is "blacked out" then DMD would be my first guess.

Let us know how it goes!

xconverge, 580V seems a bit high to me. Try forcing on your ballast as explained in this post here: http://www.fixyourdlp.com/forum/viewtopic.php?f=10&t=6&p=275&hilit=force+on#p275 The power supply you have posted a link to will work as a replacement for your power supply. Let us know ho...

WAPG2385, The light engine is fairly simple to replace if you are handy with tools. It may look a bit intimidating at first, but once you get into it, it's simple.. Like taking apart a big computer.

xconverge,

Read the bootup sequence and tell me if this helps you diagnose your TV a little bit more. Once you have absorbed all the info, let me know if your diagnosis on your set has changed and we will go from there.

ovadoggvo

WAPG2385, I can understand the diagnosis of the COLOR WHEEL being an issue if you were speaking to someone on the telephone. This color wheel diagnosis would be the most logical solution to what you are describing in words, however, after seeing that video I can tell you that the Color Wheel will mo...

ovadoggvo

WillGolfForFood, Ok.. This is a very common problem with these TV sets. Here is one of 2 possibilities: 1 - DMD Board (my first guess) - Best thing to do is buy a complete light engine from D-M since they don't seem to have the bare DMD board in stock: http://www.discount-merchant.com/SearchResults....

ovadoggvo

ZundapMan, What's the model of your TV? I would check Discount-Merchant for the part.. The best way to search their part is by the model number or the model of a TV set that takes the same DMD board ;) ... Also, if you don't find DMD board, you may want to invest $250-$330 on the complete light engi...

sciascr,
I would keep checking every week or two on Discount-Merchant's website to see if they get one instock. I've seen those digital boards come and go on there.. I think they sell them for under $100!! Which is a steal...

Other places want $300-500 for the board which is rediculous.

Good luck.

warreagle, The first step is to buy a lamp. You really can't test or diagnose your TV without having a TESTED WORKING lamp! In either case, the lamp will come in handy as it is a consumable part of the TV. It needs replaceing every 2-3 years IF you buy a PHILIPS Brand lamp from an AUTHORIZED philips...

Baum, I appologize for the late reply. It may have been a better idea if you posted in an existing thread rather than creating a new one. I have trouble going from thread to thread. Now on to the problem. The problem you have sounds to me to be an overheating issue. I would remove the back cover of ...

rbrophy52, I have finally made my way around to this thread! To me it seems like a defective Digital Board and I will explain why... But first of all, your ballast should not go bad. How are you measuring the voltage coming out? This is impossible using a standard multimeter! The startup voltage on ...

ovadoggvo

warreagle, The problem sounds like your lamp. I would definitely replace it with a Philips brand bulb. People that don't do their research about the different lamp manufacturers and the knock-offs that are in the market end up buying a bad quality lamp, and replacing it within a few months. At times...

ovadoggvo

bigbug, Here are some answers for you: "After replacing a lamp does one need to reset the lamp hour counter before the lamp will turn on again?" No. The lamp counter is not a "trigger" on the Samsung TV's. This counter applies to Panasonic and Mitsubishi ONLY. "Also, how can...

rsah, I appologize for my absense in the last month or two. I too beleive that the problem with yoru TV is the DMD board. The inverted image is a common issue on the HLN series. I would double check to make sure the on-screen menu is also inverted, if yes, in most cases the DMD chip on the DMD board...

ovadoggvo

Divenbomb, I apologize for the late help! What it sounds like is a "weak" ballast issue. Since the Philips Lamp is brand new, your weak ballast requires the full Lamp Consumption Voltage of 132W to operate. As the lamp has more use, the mercury level in the gas chamber is reduced, hence th...

Cougar, The pink shadow on the top right may be as a result of the color wheel being chipped on one of the color segments. I would check the CW to make sure its not chipped or discolored. A small chip will look pretty big on the screen. A discoloration on a "corner" such as top-right or bo...

When you installed the ballast, did you check your color wheel?

Are you sure you have your lamp cover completely and securely fastened? There is a sensor there ya know!

Moose, Are you sure you ordered the right lamp? It seems like you may have ordered a Parabolic lamp instead of an Eliptical lamp. Please put up pictures of the lamp that you are installing in your housing along with how it's installed! Bleach spray on the TV is definitely NOT the problem. If a techn...

The problem is most likely (95%) the color wheel. When the wheel is humming it means it's off balance due to a worn out bearing. This will cause grainy off color or black and white color for a few seconds while the TV tries to "bring the wheel up to speed".. After about 5-15 seconds, if it...

ovadoggvo

unclet69, I'm going to make this very easy for you! The pop/snap you heard was your color wheel falling off balance and shattering! The CW spins at around 5000 RPM (depending on your model)... That's right! 5000 Revolutions Per Minute.... When the color wheel falls off balance, many times it will ge...

It seems like the DMD Board is what is causing the above problem. I see only a slight difference in price between DMD and Light Engine on Discount-Merchant.com. I would recommend a light engine (comes with DMD Board), this way you get a spare color wheel and light tunnel that can have your TV runing...

ovadoggvo

jauxter, Even though it's way too late for me to think clearly here is my two cents: The Fan for the lamp does not turn on immediately. It will wait until the temperature starts to rise. There is a temperature sensor inside the TV that lookes like this: http://www.discount-merchant.com/SearchResults...
