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 Screen


Are you able to access the on-screen menus (like brightness/contrast etc)?


If those menus are appearing over the green screen, then it might be a cable or image source problem. I've often seen this green screen when the HDMI encryption between my cable box and my TV gets messed up. Only solution has been to power cycle the cable box.

If you can use something other than an HDMI cable to connect your TV to your picture source, I suggest trying that and seeing if you can get SD channels again. If you do get them back, it was a cable issue. If you still can't get them, contact your cable/satellite provider, see if there's something up with their signal.

Rca scenium 52" has light bar area down each side


I take it that you have watched many hours of 4x3 video on this 16x9 TV . What you see is evidence of screen burn, like they used to warn about with the old "pong" type games with stationary objects. The 4x3 pattern is burned into the phosphor in the projection tubes. the area of the burned pattern is not as efficient as the unused areas that make up the 16x9. If you watch enough 16x9 it may even out somewhat, but will never be perfect. Replacing the tubes will fix it, but they're pricey, and you may be subject to it happening again, depending on your viewing habits.

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 ,

50 INCH HITACHI ULTRAVISION HAS COLOR DIFFERENCE ON EDGE OF SCREEN


Hey, I found this on a blogsite about lcd rear projections....looks like our tv's screens have been burned by the "pillers" that surround the tv when switching from 4:3 to 16:9 or fullscreen... read below, I hope it helps !
cheers!
Vern

Rear projection crt's,the first generation widescreen tv's were notorious for that.Lcd and plasma can have the same problem,but it takes much longer and is not as harsh.Dlp's use tiny mirrors,so it isn't a problem with them.Lcd and plasma tv's should be ok unless you watch them with blck bars on them all the time.
We have lcd monitors at work,and i've seen them after a year with bad burn in.They also run 24 hrs a day 7 days a week with the same display.



GKar posted 2006 Oct 10 15:31 TooLFooL : i have 51" sony rear-projection and those freakin' grey bars burned themselves right into the screen...

I read that to avoid the burning you had to limit your 4:3 viewing time to 15% of total time viewed. (applied to my TV but apparently yours and others as well...great! now they tell you :-x , this applies unless 4:3 aspect was changed to stretched or zoomed...yuck :-x )

This really sucks as a Star Trek/Lexx/Farscape fan as they are mostly 4:3, fortunately the upconvert player/hdmi combo sends a 1080i 16:9 signal to my TV so the effects are drastically reduced by nearly filling the TV without the grey bars or burn in problem without stretch or zoom modes being used. yay! :wink: (default grey bars set to black automatically, apparently grey isn't needed due to screen area covered is sufficient for burn in not to be a problem.)

Green Plaid Screen


I think what you are describing is a form of line paring which is caused by a defective IC in the video circuit those inputs are feeding. Post a email link ad I will send a pic of a screen that has this problem and you can let me know if thats what your experiencing.
