LG 42" Plasma Faltron MT-42PZ91M

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.

If you paid by cheque or credit card, that is your proof of purchase.

The screen does not work properly .Ribbon wire fails.

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.

I wish I had an answer for you but I'm in the same boat. I've got a 42pc5d and it's doing the same thing. I'll turn it on using either the remote or the power button on the unit itself. The LED will blink either two or three times, then shut itself off. I tried plugging the unit into a different outlet. I tried unhooking all inputs (PS3, DVD player, antenna, etc). The tv was still shutting itself off. I called tech support and the lady who answered asked me if there was a power button on the unit. Well, of course I understand LG has hundreds of models but I felt like I was dealing with someone who didn't care enough to even open the manual to see for herself. Anyway, after a "reset", the TV is now nothing more than a very expensive paperweight. To say I'm displeased is an understatement.

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.

i used my plasma 42'' model MT-42PM11 about 3yrs ago i found out after a week that there is black middle bar on the screen how to solve this issue.

ysus pcb that supplies voltage to the panel is faulty

check all inputs on tv ,also check if menu on tv is working ,make sure lines arent being produce by another source, cable box etcc..If menu and or OSD are affected .Then there is a good chance you have lightning damaged some where in signal section on tv .

first i would try unplugging it for about 5 minutes to reset the set. after that i would need more detail as to the problem is there sparkles in the screen is it a certain portion of the set any info you can give
