YOU NEED CHECK THE 3 CRYSTALS ( RED, GREEN AND BLUE). CLEAN IT WHIT "DUST REMOVER" ( compressed gas duster) AND REPLACE THE COLOR WHEEL.

HI,
First thing to do is the reset and the whacking test. I give this a 50/50 chance of clearing it up.
ONE: Disconnect the power cord for 4 hours. Then when you power it back
up the internal soft codes will automatically reset to factory defaults.
TWO: The whacking test is to just bang or smack the set with your hand
on the back, side, top, etc., to see if there are loose connections or
cold solder joints inside that are acting up. If so, the banging should
knock them back to normal and the set should restore. You might have
to use some creative banging and some have had to put a book or
magazine under one corner to torque the chassis enough to get it to
work reliably.
If these two procedures do nothing then:
The manual always knows the best.Go through the manual carefully and u will find the solution to ur problem..
Goodluck and Kind Regards

Hi, Depeending on the thickness of the lines matters. If the lines are Black and about 1-2 inches thick it may be a bad bottom buffer board or a bad panel (screen).
If the lines are thin 1/16 to 1/8 inch it is most likely a bad panel.
You can open up the set and depending on the model, see the thin board/boards running across the bottom with ribbon cables going to the panel. You may be able to attempt reseating the ribbon cables, but be careful as some retainer plugs break very easy.
If the lines are thick black and the reseating doesn't correct it you may be able to buy the coresponding buffer. Unfortunately some bottom buffers are actually part of the panel. If you are not comfortable taking it apart then call a professional but be aware labor charges start around $200 not counting parts, panels start at $600 up to over $1000
hope this helps
Thanks
Eric
