    This set is from yr. 2000. I know there are some boards ( 2 or 3 ) that plug in like on a computer. Could this be one of the problems. If so, how do I find out which one it is.

  • ElPason Apr 27, 2008

    The Panasonic model # for this set is Pt-51SX60.

    The Panasonic model # is PT-51SX60. Hope this helps!

    Is there any instructions on how to polish the mirrors or replacement of the coolant?

  • ElPason Apr 27, 2008

    Slinteriors, thanks for all the information. The link was very informative. I'm a bit of a klutz so I might just have the process done by someone who knows what they are doing. At least I know what the problem is and can relate it to the service man.

    I accidentally broke the rear projection mirror, can this be replaced?
    Could I have a local glass company cut the same size and thickness
    material (mirror) or is this some special "mirror" material? Does
    anyone have any idea or suggestion?

Try polishing the mirror and CRT lenses. If that doesnt help you may need to change the coolant in the CRTs. If your set is a DLP you may need a new lamp.

    your problem is with the mirror being dull or the coolant needing replacement

    the mirroe has to be polished by removing the frony screen or just reaching up from the rear panel. The rear panel takes alittle strecthing but is do able. Heres a link that will give info on coolant changing.

Picture getting dark


My jvc 27" tv was so dark I could hardly see any night scenes, even with the bright all the way on. If you push the sleep button, let go, then hold down the video and display (together), the service menu will come on. Scroll down to #7 (too dark) and adjust the brightness there. Works immediately. Good luck.

Picture is very dark


Is there a simple fix for this, yes The picture is very dark it is mostly due to 1 power supply output is low. 2 voltage on crt g2 pin is low. 3 video output supply is low. 4 some components in luminance section might be defective or loose. 5 finally crt getting weak but as you have bought in 2004 so possibility is rear. good luck

The picture is very dark


Unfortunately, there is no easy fix for this. If it were a rear projection TV, I'd suggest a new bulb. Even on a Plasma there are things that can be done. But on a CRT, the repair for a dark screen usually costs more than replacing it.
