    Many people say that if you replace the Z Sustain you should also replace the X Sustain. What is your opinion?

Your TV is going to need a Z-Sustain PCB.

The Z-Sustain controls the contrast of the image, it is also a common part to fail.

50px1d-uc When I try to turn it on, the red power light blinks, I hear a click, then the light turns amber then back to red. Usually I'd hear the click then it would turn green and the tv would work...


I came across this in a manual
-Without CableCARDTM : Illuminates red in
standby mode, Illuminates green when the
TV is turned on.
-Inserting the CableCARDTM : Illuminates
orange in standby mode, Illuminates green
when the TV is turned on....
You might want to check your cable card. It seems to mimic your problem. Try taking the card out and gently clean, with a dry cloth, the contacts/strip. Then take some "canned air" and blow out the card socket from the side to dislodge any accumulated debris.

TV LG Model 50PX1D-UC Flat Panel Television Loud Popping Noise. TV goes out. I turned on my tv the other morning and it let out a loud popping noise and the picture went out. Any suggestions...


Hello,

The problem is that there is a bad capacitor inside the unit, it is either on the main panel or the power panel. The popping sound you got was due to the fact that the lead on the capacitor was bridging, therefore causing some electrical popping sound.

Run a check on the main panel and the power panel for any bad capacitor and replace it with a new one. That way, your television will be in good condition once again.

Take care and good luck

I have a LG 50PX1D-UC plasma TV with a black vertical line


You could have a Driver Board that has a loose connection or a Ribbon Cable that has a intermittent connection to the Plasma Panel, or a defective Plasma Panel. Either one could cause the problem and I would recommend only a Qualified Service Person to check it out.
Here is LG's Customer Service Number. 1800-243-0000. They could direct you to a Local Service Facility.
I hope this helps,

As I was watching TV last night, my 50" LG Plasma TV 50PX1D, and it made 3 loud "popping" sound, and you can barely see the images. The picture is not jumping & the color doesn't appear to be fading in...


Either X,Y, or Z-boards seem to have developed a problem, when this happens it results in a 'sound-no-picture' condition. If its under warranty take it back, if not have your local tv repair center fix it for you....

42 inch LG Plasma TV - Lost picture


Hi , I recently had the same problem which I was determined to fix . So I did a few weeks of research to find that it was the Y SUS board which burns out. I'm sure you realized that the TV gets hot. Personally I think this is why. circuit boards don't like heat and I've learned that the cooling fans are a joke. I replaced the board and got my picture back. I proved the fan theory because after the screen started to act up. I placed a cooling fan near the vent holes on top and the problem cleared right up,It also helps if you lower the brightness which helps out on the heat situation.I will soon be adding a fan with a temp. sensor. This shoud help if your screen has lines when you initially turn the cool TV on.then I have Some other costless solutions. Hope this helped these are great TV's and like our cars we maintain them not throw them away..................................Mr Wiseman
