Re: Zenith pv5263bt 53
If this is a projection TV, first you should check you lamp. Is it good (clear) or bad (foggy). If foggy, you should replace it. If it is good (clear) reseat it back onto the ballast (it just might be loose). If you are still having this problem, you probably need to replace the ballast

Hello ksolovy, i understood your Problem with the Sony KP-53V90 53 in. Rear Projection Television,In fact i encountered already that kind of problem you have it now. Check first the color wheel im sure that the blue section of your color wheel was burned and the blue color turn to dark; That's why you have seen dark picture, Re-place color wheel.
It could be that the picture tubes have gone down on emission, there is a prcedure that can be tried to bring up the overall brightness but it is just possible that you will loose some picture quality. If it's a 1994 projo tv i am thinking of the three crt system, a gray scale alignment would probably correct the dark condition in your picture, again depending on how far gone is the emission in your picture tubes, if your projo tv is the dlp system, the bad news is that you could be needing some light engine repair. The color adjustment is possible with the availability of a service manual or in the case of the dlp system, light engine repairs or replacement are available from some on line stores.
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.
The Picture tubes(not bulbs) do and probably are weak. There replace should only be done by a trained service person. One reason would be the hI Voltage issues related to the crt's, as these tubes store alot of HI voltage even after its unplugged for a while, and another reason would be that these tube can very easy implode then explode and that wouldnt be a pretty sight. Third would be the alighnment involved after all three tubes are replace. There ba cross hatch generator and alot of time involved with the alighnment. Please seek a pro to assit you when your ready to spend at least 900 TO 1000 bucks. Good Luck
