SOURCE: 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.

SOURCE: Visio 42 in Plasma turns on but no picture

Just had the same problem and determined it was the primary power supply board. The TV has a primary and secondary power supply. The secondary controls the on/off and audio. The primary controls the picture. If this is shot, you will not get a picture but will hear audio. I had to call Vizio and have them send me a new power supply board ($150 + SH). Not too hard to install yourself. Hpe this helps!

Why won't my Panasonic 42 TCP42S30 42 Plasma TV turn on.


Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, I suggest it is better to refer it to a qualified service
technician, since the back cover has to be opened for investigation/rectification.

I have a 2006 Hitachi Ultravision 42 inch plasma


plasma tv units use a lot of power ,well into the hundreds of watts 9 some big screens use up to 800 watts to work)

Your powerboard is damaged, and need to be replaced.

Sometimes it appear the TV is working again with no problem but it is only a matter of time for the board to get completely damaged.

This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.
