These are different effects that will come on to the screen to help prevent plasma burns. It is a similar idea to a screen saver on your PC if the image is static for too long.

You want to replace main power supply module, the caps can look good, but still be bad.

This condition, sound no picture, is generally a result from a failed y-sustain and/or x-sustain board. You can check the fuse for continuity or resistance using a multimeter. I am helping someone repair their LG 42pc3d, that's why I thought I'd help you out too.

Y sustain board 6871QYH053B
Z sustain board 6871QZH056B

Yes usually the x and y sustain boards go. Not always with both fail, but they communicate with eachother...this is why replacing both is "good practice." You can check shopjimmy, ebay and encompass parts for parts online. Just order new replacements...you can tell a bad board usually by burn marks, popped capacitors, etc.




Good luck and thank you very much!

The smaller picture is PNP called picture and picture.It can be set in to the menu setting.Go to menu setting and search the PNP code.Try to off or diable the PNP menu setting to back the normal single picture.

It's time to visit the local service center, or replace the TV.

Hi,

When there are blocks missing from the screen ( dark or black spots ) the usual culprit is the "logic buffers", they are circuit boards that are spaced evenly across the top and sometimes the bottom of the TV on the inside.

They control the addressing of the picture information on the TV. When one goes bad then usually a large block of the picture will also go out.

I do not recommend a DIY fix on a plasma TV as it is a dangerous high voltage environment inside there.

If you have electronics repair experience and would like to repair it, revert and i would be glad to add few inputs to the diagnosis.If you call in a pro you can look to spend about $200-$300 as the buffers aren't that expensive.Be advised that in few cases, it is faulty screen, however more often it is bad logic buffers that cause this.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Hello,

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.

I hope this will help in solving the problem....

It sounds like the screen or lighting in your tv might have died.

You mentioned on our call you where playing on a PS2 and the tv went to black but with sound.
Sounds like what we got here is one of the boards in the TV went defective, thus the TV would need to be taken to a repair shop for further repair and diagnosis.
Plasma TV's are not new tech so to speak they do have there hiccups after some time.
I did mention some part numbers for two different boards and a reference to a company that will come to your for the actual repair.
I do hope your call to us was helpful,

Hello
Just check the remote control for its infrared emission. You can do this with a cellphone with camera option. Infrared radiation is not visible to human eye, but electronic camera can sense it. Hold the remote control about one feet or so away from the cellphone camera lens, after set the phone to camera mode, press each button on the remote handset. If infrared emission is there, you can see its image on the screen of the cellphone. If there is no image, remote control is damaged. If there is image on the screen; and still your TV not respond to it, the infrared sensor inside the TV is faulty and shoould be replaced. OK.

From your description it sounds like your TV it's actually on you just can't see a picture. That is usually caused by your Zustain boards. The zustain boards are located on the left and teh right side of the TV. You can check the fuses to see if one of them is blown or you can leave it on and see if one of them does not heat up. You would have to replace the board. You can find part at www.interliquidparts.com

This is a universal remote u bought wright?Check ur tv remote owner manual follow the instructions and program in ur tv universal remote codes for ur tv universal codes.If none of the tv universal codes of ur tv model will work,return it.Try website like Remotes.com to buy the tv original remote or very close compatible to the original one.

Y and X-sus boards should be replaced at the same time due to they way they communicate with eachother. I suspect that the x-sus is also faulty.



Thank you!
