I have a sony fwd50px1 plasma monitor. There is a black bar at the top 1/4 of the screen. A popping was heard from the back of the unit when this occurred

Ur tv have burns capacitors,look for pop ups caps.

Lamp inside TV is broken and requires replacement. Pop sound was its breaking sound.
Lamp replacement procedure is written in user manual, pretty easy.
Please buy Sony original lamp for TV safety and avoid aftermarket/ cheap lamp.
Let me know if you need to download user manual copy.
Thanks.

No! have a LG service center look at it.

yes, stop using a plasma TV as a computer monitor. Using the TV this way is an invitation to phosphur burn which these are very prone to. The issue you describe is due to the limitations of the TVs scaler circuit to properly center the image in 720P.

You may have problem with y-sus or z-sus board.Before conclusion I would say check whether this unit has been upgraded the software or not?

I think that the pop you heard was an electrolytic capacitor blowing its top on the picture frame board. If you are able to check this for yourself by looking on the board for the one/s with a bulging top or are a brownish/black colour like something has caught fire. And also in this situation smell can be of great help as it will smell burnt out but PLEASE before putting your nose or anything else in the tv take all necessary precautions against electric shock and discharge any electrolytic capacitors in the vicinity. If you are not able to do this yourself find a competant technician. Hope this helps.

i thin i best u not opening it up ur self just make sure that the fuse in the plug is still working and see if the light on the power pack is lit other than that its best gettin a proffesional to look at it hope this helps

Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.
