we cannot get a picture or sound on several channels. Otherwise the TV works fine. Any solutions?
as you get p&s on several channels so your ser is ok the problem
1 loose contact near tuner or it is defective.
2 tuner signal line .
You will find that the power supply has failed and is no longer supplying the VS voltage that the screen requires to produce a picture. Call a specialised engineer that is authorised to work on your make ot TV.
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.
Following up on my Feb 7 post. My new lamp arrived, and I replaced it and it works great. The old lamp had many shards of glass come out of it. It was tore up. I saved some money buy purchasing just the lamp and not the cartridge. It's a little bit more work to take apart, but saves money. Mitsubishi wanted $289 for the lamp replacement kit. I got a lamp for $114. TV is working just fine now!
It sounds like the popping noise you heard was a capacitor blowing its top somewhere in the tv. Sorry I cannot be more specific but if you manage to find out where this cap has gone also check any resistors near it as they can be also damaged. If you cant do this call out a competant technician. Good luck.
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.
* The TV set may be unplugged.
* A fuse or circuit breaker may be blown or switched off.
* The remote control unit (RCU) may be disabled.
* Make sure the TV/VCR are plugged in and the wall switch is on.
* Check the fuse or circuit breaker. Test the outlet with a lamp.
* Replace the RCU's batteries: if this fails exchange the unit.
