It sounds like the TV was most likely dropped, and there is probably some breakage! I would call right away to have the set exchanged!

SOURCE: no picture on flat panel tv. has sound

Sounds like the digital control board, 6871qch038a Lg Digital Control Module subs to 6871qch038c. But that's just a first something I would check in this unit. Replace also capacitor C19, 630V big blue square cap very common failure for no video. You might want to shop this one thee are a host of problems with this unit that would certainly get some needed attention if a qualified tech were testing it and looked up the bulletins.
Good Luck!

Rainbow static on Plasma Tv


The color static, if we are talking about the same thing, is usually a digital signal interference. Check cables, and digital converter if used.

JVC LT47 that picture goes black (sound fine) after being on for awhile. Can turn TV off, then back on & it's fine. But then happens again about ever hour or so.


Hello
Hello
It is due to some loose soldering points [dry soldering we say it technically], in the power supply section of the TV. Just check for it. Check the solderings of all components, that will heat up to an extent when the TV works on. Repeated heating and cooling may make solderings to the terminals of that components to get loose. Just resolder all the suspected solder terminals, by applying a little more solder, without making any solder bridge short in between adjecent solder terminals. This must solve the problem to your tV. OK.

My son was bouncing a small ball against the screen and then it went to looking like a rainbow. Would this be the picture tube?


He may have caused some type of damage to the picture tube, but usually rainbow effects happen when magnets are present. Perhaps the ball became charged with a large amount of static, which then discharged across the tube, damaging the controlling circuits.

Philips HD/TV rainbows the picture at the bottom of set.


Hi, the convergence circuit is getting ready to fail, fix it NOW and you may get away with just resoldering the STK`s, soon they will overheat and short then it`s going to be 250-300 to fix it depending on your area rates, gl, video-tek

PS3 static on screen


It sounds like you're carrying interference to your TV. Try moving you station away from any power source. Make sure your hdmi cable is away from any power as well. This may also be a ground issue. Plug your ps3 power brick into a different outlet.

Picture goes off


A temporary solution is to unplug the TV for a few minutes, remove static from the glass with your hand. It is important to unplug rather than turn off. If you have a degauss button you can also press that before unplugging. Wait several minutes or an hour. Then plug it back in. If you have Picture in Picture it may be an issue with that and to permanently solve may need a repair person. The unplugging may get you by for a few days at a time. That's at least better than an hour.
