Question about LG Televison & Video

`How do I fix my LG tv? It's making a high pitched noise and there is a black screen, is it fixable?

We have a 5 year old LG plasma HDTV 50 inch, about three days ago my husband was watching when it started making a high pitched squealing kind of noise, he was unable to turn it off with the remote so he pulled out the plug. Now every time you turn it on the noise is instant and there is nothing on the screen at all. The only way to turn it off is by pulling the plug.

Get it to a tv dealer but my guess is its died. It may not be economical to repair but you may be pleasantly surprised and its a small job. LG are usually pretty good so I'm surprised its gone at this age.

SOURCE: My 50'' Samsung Plasma has dead screen after only 2 years

Hi,
welcome to fixya!
without doing voltage checks, my best guess is this:

Plasma hpr5053 or hps5053 models will burn out a buffer board or both, there are two buffers and the Y board.
I usually change all 3 at once, but if on a budget you can try to remove one buffer and see if you get half picture (upper or lower)
this is something only a technician should attempt. the boards cost $200 each (buffers)
$300-$400 (Y board).
if you actually get half a picture the Y and one buffer are good, a bad buffer usually burns out the Y board. and in really bad cases the panel is bad also (not common, but possible)
For part#s , specific help you can post a model# , but again this is a repairmans job not something the average customer can fix.
hope this helps
Eric

You can't upgrade a panel tv, plasma or LCD.You may have had a plasma panel failure,I sell LG tv's and for the panel to go bad is rare but I have had it happen approx.6 times in the past 5 years.I highly recommend contacting LG"s customer service they will stand behind the panel and get you going again.Good luck!

Thin horizontal line,about 6 inches from bottom,is it fixable?


I am assuming it goes all the way across and is black ?
It sounds like a scan line in one of the chips inside has gone bad or needs to be resoldered. Most likely needs the board replaced by a tech.
Hope this helps

LG 50" plasma tv


call 877-543-8325 this is an LG Executive call center and they will fix this for free. I have a 50" plasma I bought january 2006 which is out of warranty by 5 months. They faxed me and the LG repair shop a 30 day warranty for my tv to cover the repair. Just tell them you heard a pop and in my case the picture is distorted. All they need is the model number and serial number and they should take care of it. No arguing needed.
