Question about Televison & Video

Open Question

My LG 42LB9DF plasma TV worked just fine when I bought it a year ago, but the reception is now intermittently breaking up (pixellating) and the sound is will make a noise and cut in and out. We can't work out whether it's the antenna, or if it's the internal tuner?

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: no picture but sound on panasonic plasma

Unplug the TV and disconnect any HDMI cables to the set. If the issue goes away there is a possibility that your HDMI source is causing the problem. Anything on the HDMI can cause odd problems with the TV since the serial data and serail clock lines are routed on HDMI. Those are the 2 commmunication lines used throught the TV for operation so anything HDMI that might load down one of those can cause issues.

Check the arial cable - not just the connections. Problem noted was due to an inferior cable that was not up to the job. It also ran alongside a central heating radiotor and pipes - not a good combination apparantly!

SOURCE: signal issues with my Insignia DTV converter box

As far as the antenna goes..NO. It is still an RF signal. The antenna just needs to be good for the frequency range of the stations you are receiving. The station numbers and frequency don't necessarily match like they use to. They are all over the place now.

Get sound and "invalid format" message displayed instead of picture


Could have still been hit by a surge. Take the back off of the TV and look at the main board were you connect your HDMI. See if it is scorched or components that blackened. Also check your DVD player on another set. Your DVD player could be the problem.

Get in touch with your cable operator and measure the strength of signals being received via the Cable. It can be boosted by the cable operator from their end or attach a booster on your line...............sodeep

Plasma TV smell?


a smell from a plasma is usually a electrolytic capacitor leaking.  Luckily, replacing capacitors is very easy.  you can do it yourself if you have any skills at all, and if you can identify it.
just google what i am saying, you should be able to find the info you need to replace them.

Samsung 42' plasma tv,screen keep flashing, blurry,no pics


I'm not really sure what causes this but I might be able to help.
I have an LG 42 plasma which had the same problem. In my case I removed the video and the tuner board (they both were mounted on the same frame which was screwed on the tv chassis) and installed them in a "wooden box" so that there would be no electrical contact with the rest of the chassis except from the cables connected to them. It now works fine.
