this has happened three times, we've repaired it each time at a cost of 700$ and it keeps happening!! we have heavy duty surge protectors, so that can't be the cause, it just works one day and not the next
its a total piece of junk!!!

i don't recommend anyone buy this tv--or lg--ever

have the same problem with nec.noticed that if cool warmth applied went away until set turned off.tried freezing could bring lines back again .tracked down to certain area.thought might have been dry joint.but problem got worse.now is just coloured lines .every thing else works okay.when go to wide view lines will open up and close as you adjust screen.

Horizontal bright line sound is fine will sometimes go normal with hit to side of TV

Sound like cold solder joints on the vertical output ic. The vertical output ic is usually a inline 7-9 pin chip that begins with la prefix. Not hard to repair at all just be careful not to touch anywhere near the anode leads to the picture! Basically it will knock the **** out of you. lol..

Sony gv-27v42 27" tv picture cuts out after a few minutes

Vertical lines down the center only means that you have a loose connection on the Yoke. Re solder all the connection on the yoke and where the yoke connection meets the main board.

Picture broken and shrinking

You need to change your vertical IC, along with some capacitors around the vertical IC. Capacitor with value 220UF, 10uf, 470uf and finally 1000uf. Doing this will fix the set. Total cost under $40

LCD SCREEN

Do you have a picture showing in the viewfinder when the LCD is closed? If not, it's a bad CCD and I believe Canon will fix that for free if you call customer service.
