Plasma tv no picture no sound blown fuse fs2


The problem here is you cannot even find that---I suggest you either buy the y sustain board as only circuit boards are sold and NO parts themselves or take it to a shop for an estimate.

I have a LG 42pc3dv with no picture just sound. I have this tv over 3 years, other people experienced the same problem, some of them mentioned the Y sustain board. Is this an easy fix.


Check the fuse on the Z-sustain module. The module all the way to the right (looking from the back) If blown (and before the set went out there was a loud pop) you need to change the IC on the Z-sustain part number STK 795-820 or 821 and the fuse. If you don't want to bother unsoldering and soldering back this part and you know the fuse is blown then replace the Z-sustain module. Do a google, ebay, or shopjimmy.com search with the model number for price and availibility.

HI I HAVE A LCD 42" LG TV< AND AFTER 3 MINS OF TURNING IT ON I HAVE NO PICTURE BUT SOUND IS WORKING PERFECTLY HELP???


Hello,

no picture and sound is OK => The problem is from the
Y Sustain problem. However, normally they have to change both Y Sustain and Z Sustain boards at the same time. If you lucky than it's just a fuse on the Y sustain blown (the chance is very rare) otherwise the IPM (Intelligence Power Module) on the Y/X sustain board is short. This is a common problem and costly repair for Plasma TV.


Hopefully, it's something simple to replace like the fuse.

good luck in solving the problem and be careful in handling it, because the Television is fragile and contain high voltage in power section of the power board...

Ihave a LG 42 in plasma 42PC3D; there is areal faint picture and normal sound, tried everything thing.adjusting brightness to all other troubleshooting methods, still faint colr pic norm sound. Please...


it is going to be a failure of the Z sustain board if you can see dark video. you can either replace the Z sustain board or the IPM that is bad on the Z sustain. the board is about $175.00 or so part number is 6871QZH034 I THINK.

My plasma tv has just lost it's picture. I do have


There will be a fault in either the Y or Z sustain boards, these are responsible for driving the screen 9hence sound but no picture). The popping sound willhave either been a fuse blowing on the board or another possibility is one of the drive ICs on the buffer board has blown. If so it's best to replace the board.

LG PDP42X3 No Picture - I have sound and blue power button in front but no picture. How do I tell if the ceramic fuse is blown? They are all still pure white. If they are not blown, does that help with...


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.

LG plasma have an amber light when turning on then green then red


After all the research I found out that the IC on the Z board is bad and new board was ordered and replaced. The plasma work fine after that and picture is excellent with the new board. This forum is great, without this I couldn't fix it myself. Thank you.

Loud pop


If there was a loud pop then it would appaer a fuse has probably blown either on power supply especially if there is no indicator light showing. If you are getting the red stand by light then possibly a different fuse on the sustain board has blown. You would need to remove the rear cover & check any of the fuses. Most likely if they have blown something more serious has occured to cause & replacing the fuse will result in it blowing straight away.

Sound but no picture


It's very likely the fuse on the Y-sustain board may have gone open circuit due either a fault with the sustain board or the buffer board. If this is ok then check if your Vs & Va voltages are present when switched on if yes you may have a fault with the control board.

42 inch LG Plasma TV - Lost picture


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.
