Question about Samsung HLR5067WX 50" Rear Projection HDTV

Green Plaid then Vertical Lines, Failure of hard controls, Analog Board?

Dear Sir

I have a Samsung 50" DLP Model HL-R5076W (model code HLR5067WAX/XAA) type number AT50L6 made in August 2005 (bought new) its worked fine until recently when it started to have these symptoms...

On an analog input (DVD connected to component input) it came on with non-moving plaid-like pattern of lines, the picture was mostly green (with some blue/purple tints) and slow moving.. i.e. maybe only about 1/4 normal frame rate, until finally the picture would lock up and then the sets controls would lock up (non responsive to physical buttons on the set OR remote control input, although the remote indicator lamp will flash on the set when you press a remote button). Had to unplug/replug to reset the set.

Comes back on, didn't have the problem immediately but then it came back after a few minutes. By plugging/unplugging I was able to determine that it only does this on analog inputs, digital inputs (HDMI, PC/VGA and AIR- with a HD signal) all work fine.

Also... if displaying an analog signal WITH the plaid pattern, if I turn on the TV's menu or the TV-GUIDE that content displays just fine (over top of or including PIP with bad plaid but main display ok).

The problem has become steadily worse to the point that now its not doing the green plaid lines, but locking up and going to a blank screen very rapidly... now does this on digital inputs sometimes too.

I am an electrical engineer and purchased the service manual, and I believe the problem to be the "analog board" since it seems to process all analog signals before handing off to the digital board AND because it processes all controls (physical buttons on the set and remote control) plus the power supply routes through this board to other circuits within the set.

I know the lamp/balast are ok, color wheel is spinning and the DMD/Light Engine must be ok since it can display the TV's menus and TV-GUIDE just fine. Equally the power supply itself must be ok since things are working normally.

In your opinion am I on the right track? do you think replacing the analog board (bought from samsungparts.com) would be my best option?

You can reply to bmharris@mindspring.com or ben.harris@harris-educational.com with your answer.

Thanks for your time.

Green plaid vertical lines across the screen. This goes away once I unplug and then replug, and lasts for a few days. This worked for awhile, but now it's becoming more frequent, and resetting doesn't work. Lated in addition to the green lines, the screen goes black sporactically for a few seconds. Any suggestions on getiing this fixed?

As you are an electrical engineer you under stand that the micro mirrors of the DLP module "warp"
+/- zero to 30 degrees on three planes R/G/B to diffuse the three divided light paths then: are colorized by the color wheel. Since the analog power amplifier circuit elecromagneticly "bends" the pixel mirrors your anilog board is not producing a large enough voltage to "tip" the substrate mirrors so; measure your output voltage on one of the "good" outputs: i.e. Digital and, with your oscilloscope measure the analog board output You should find that the analog board is producing a lower voltage output to the elecromagnetic "mirrors" Usually this is caused by deteriorated capacitors.
You probably can replace these yourself and, save money.
Or, as I agree: replace the analog board if the input supply B+ voltages to all output boards: Analog and, Digital are the same.
Hope this helps

Green Plaid lines on Samsung HLR5067wax/xaa-


These are the Tests that should be run to determine which board is bad.You should call a good TV Tech if you are not familiar with this TV.
- The DDP1011 on the DMD board has a feature to display internal test patterns.
- DNle, which is an end port in the digital board, has a feature to display internal test patterns.
- The analog board sends signals to ADV7402 on the digital board.
- The analog board is the first output and the digital board is the second one, followed by DMD, which is the final one.
■ Diagnosis By Module
1. Access Service Mode
(In Standby mode, press "Mute", "1", "8", "2" and "Power" to turn the screen on and enter service mode)
2. Check if there is an error in the DMD board
DDP1011 → TEST PATTERN → Press the right arrow key:
Options of FULL WHITE, BLACK, RED, GREEN and BLUE PATTERN are displayed on the screen.
If "Pattern" does not appear, this is a DMD board error.
3. Check if there is an error in the digital board before the DMD.
When the DMD board has been determined to be error free based on the test patterns:
FACTORY MODE → DNIe → TEST PATTERN normal display: no error in the digital board.
If "Pattern" does not appear, it may be from a DMD board or ATI error or there is an analog board malfunction.
4. Check if there is an error in the analog board.
Check for a power signal from the analog to the digital boards

Green Plaid then Vertical Lines, Failure of hard controls, Analog Board?


You are absolutely correct, When anyone complains of vertical lines or bars, the next step is to see if it happens on only digital inputs ( digital board ) , only analog inputs ( analog board ) , or both ( DMD board ) .

Analog board can be purchased at www.partstore.com ,
