LG Rear Projection TV Model RT-62NA31RB

The picture disappeared suddenly! Several technicians have tried to repair it and failed. Now there is a feint picture but there are thin, red and green lines, in pairs going across the screen, in an oval shape. Sound seems to be ok. I live in Beira, Mozambique, where technology hardly exists! Please advise - thanks in advance. Kind regards, Perry

hi there, i had the exact same problem as you and this is how we solved it. Instead of replacing the convergence IC's as suggested above, which requires soldering and de-soldering, which could damage your board (this happeend to us). Order online part # SSB-5068A. This is the ENTIRE convergence board with new IC's. Cost you about $140 (from vance baldwin.com) but is a lot less hassle than you trying to soldering/desoldering parts. Only thing is, next to the 2 large heat sinks, there is this large silver component that you need to unscrew from your old board, and unplug and attach to your new board. We tok the new board..hooked up all the wires..and voila, no more convergence issues.

the problem is vertical collapse,i am not so sure you can trouble shoot this on your own but you can send the board to eithor pts electronics or tristate module for repair
to get a price get the number off the sticker--left hand board(looking from the back) it will start CTC195---- write down entire number before you call them

Thus problem sounds like you have some failed capacitors on the power supply circuitry. I have had this problem on an older TV and it was solved by replacing the popped caps. Do not try this repair yourself, unless you are confident you can do so safely! Also make sure that you unplug everything before poking around inside!

This television needs to be repaired by a qualified service center or replaced. There is no adjustment that can be made at home to fix the problem you have described.

The HD capabilities seem to have disappeared?


no idea on your exact problem yet but LG the manufacture of this unit had a recall on this model for several issues and they are paying for out of warranty repairs for certain problems you may want to call them and see if you can get some help from the manufacture.
