Question about LG Projection Televisions

1 Answer

A 2 inch wide blue line just came up on the right side on our screen. It goes from top to bottom. The model number is mu42pm12x. The weird thing is that it happened right after the remote (which is actually the cable remote) got bumped and made a popping sound. The remote is working fine. We unplugged the tv and let it set for 30 seconds and then turned it back on but nothing changed. Any ideas?

    We left it unplugged all night and then reattached the power this morning.
    The line was gone for about five minutes and we thought we had the problem licked, then it reappeared.
    Then later today it went away for a couple of hours all by itself and then reappeared.
    It is light blue, an inch and a half wide and transparent.
    You can see the picture through it.

Hmmm...when the remote was bumped, as in stepped on, perhaps? or dropped? the tv itself would be unlikely to be affected in the manner in which you mention, due to this.

unplug it and let it set for 20 min, then report back here, please..

You have a defect in the convergence circuit. Both chips will need replaced and possibly a resistor or two. Chip part numbers are STK392-110. Typical repair runs around $350

I have a blue line about 3/4 inch wide from the top right to the middle bottom. ( not a straight line ) I replced thr projection lamp with no fix to the problem. I added an additipnal fan and cleared up the problem. On furthe investigation I replaced the air filter and kept only the original fan and the problem was solved. Can you explain this.

Convergence


Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.
