Sounds like you could have a bad Picture tube, as the filaments may not be lighting, as they are open, or maybe a video problem, or perhaps a problem in the Sweep power supply. This is an inexpensive TV set and will most likely cost more to repair then you could purchase a new TV for. Good Luck

Hi I have 32LG3000 there was some static discharged from me to HDMI cable to the tv and now the picture is shutting down after 5 sec so basically I get picture and sound the top half of the picture is...


The spark has damaged the image processor - the entire mainboard (the board that carries the processor and the AV connectors, including the HDMI) will have to be replaced. The board will cost you around £50 - you can buy it from here

or you can order it at a dealer

I put banana clips on the wires and plugged them into the Insignia 200w audio receiver and everything sounds static tv and music


For temporary just for testing it ok.. but using banana clips permanently it not a good idear because due to excesive sound vibration it will create static for sure to avoid that you may have to souldering those wired in place to avoid that static and causing eventual damage inside your receiver... any conection as to be well connected special went it time to connect a large amps., beside a turn table, you may look for a good ground.... I suggest to put a solid ground wire also betwen your tv set and your receiver
for eventual hi static discharge., also make sure use a power bar for more protection ...good luck

Vertical line down the center, sound OK.


This is the deal. Your picture tube is going out. How thick is the line. As it gets wider that will tell you how much more time you have. Was the TV dropped? There is a way to adjust this but you have to get into the back of the TV and if the static discharge is not done properly it will kill you. Don't mess with it. It is now cheaper to buy another TV on craigslist or your local paper than trying to repair it. Hope this helps.

Problem with RCA TV Model 27F634T


You almost certainly have a bad picture tube. The green screen was from one of the elements inside shorting out. The static sound you're hearing is the high voltage arcing out through the end of the picture tube to other parts inside the set. It's more economical to buy a new TV than to repair this one.

Sorry to have such good news, but this is one of the ways a picture tube can go bad, and it happens quite often.

Screaming static


Try turning off different lights near the room or in the room that it is in. Our tv does that if the overhead light in our bedroom is on, it's a room right next to our living room.

No picture subsequent to "tin foil experiment" on screen


Static discharge to the TV can cause lots of strange things to happen, replace the main board and your problems should be fixed

Tv seems ok by static and now, no sound (or very faint)


The problem you're describing sounds like a tuner problem. BUT you say that you have the same problem with A-V input too. That's weird!!! Possibly the electronic TV-AV switching circuit is messed up and stuck in the TV (tuner) position. If this is the case you DO have a tuner problem and a switching problem too.
