 |
|
I have a Sabre LCT47PBKA that appears to have some sort of backlight issue. It looks like the screen is broken in to 4-5 panels that go from bright to dark and run horizontally. Can anyone confirm if this is a backlight or LCD panel problem? I can watch the set the way it is, but would like to get it fixed is possible.
Thanks in advance, Jim

Sorry to inform you that SABRE is out of business (bankrupt). there are no distributors, parts, etc, etc. I know because I was a warranty authorized servicer for this brand.

Yes, I know they are out of business . I am able to scrape some parts up around the net and am also capable of component level repairs. I'm really interested to know if this is repairable. As in is it a LCD panel issue (not fixable) or a backlight issue (easily repaired).
Thanks again for your help. |

Frankly, I have never seen quite this symptom before, Usually a backlight issue does not have defined departure lines like those shown in your pictures. However, due to the fading as it goes across it would seem to be a backlight issue. I have never tried to change any of the backlights even though if you are careful enough it is technically possible. Individual lamps for the backlight are available here: http://lcdparts.net
Hope this helps

| Ive never seen that before either. But I don't think it's possible that the backlight could cause that symptom. |

I've replaced a few backlights in monitors and small TVs. I just ordered a bulb for a 22" samsung that I got from ebay. You can get some good deals on these things of you are handy with a DMM and soldering iron.
I suspect the backlight because it appears dark in the bottom right of the picture and it gets lighter as you move away. That to me indicates 1 bulb is either very dim or out altogether.
Thanks again for your help and input
