THe coolant in the CRTs most likely needs to be replaced. this is a very common problem in Phillips and magnavox rear projection TVs.

SOURCE: my picture is dark and have changed the brightness

This model is notorious for needing a new lamp about every 2 years. The lamp is accessed through the front by removing the long plastic cover under the screen (it just pulls off). Under that, to the left of center, is a square cover with one grey plastic screw. Loosen the screw and pull the lamp assembly out. It should just slide right out. Turn it around and look at the lamp. If the lamp face or reflector looks "cloudy" or "misty". Replace the lamp with Philips part number TY-LA1000. Just Google the number and you will find them available for around $100

Hello!
Well it seems that your lamp is about to go out, replacing the lamp might jus do it ! Also make sure you get a Philips lamps, they work like a charm.
And regarding the long plastic cover just be a little bity patient and you'll make it come off, just make sure you do remove all the screws.

@ 6 years old I'd be willing to bet that it's time to replace the lamp. They lose brightness over time so that could be what the problem is.

PICTURE DARK


I had the same problem soI decided to go ask at our local tv shop Panasonic warranty place and he was nice enough to tell me the problem . So for everyone reading .. these had a defect with some of the disc capacitors they used on the CRT board it as 2 on there . The second problem is with the ``YC`` chip . panasonic sets have many unusuall malfunctions caused by this chip such as a black & white picture or brightness problems . unfortunatly my set has a bad chip . There we all learned something today . he invites you to contact a Panasonic ``rep`` he will tell you the same thing .
