Toshiba 53HX71 Proj CRT television - colors missing with HD only

Hi ! Recently bought this TV used from a friend. Analog interfaces work good. When I try to use the any one of the 2 Colorstream interfaces, the video is there, but it is like some colors are missing, and the pitcure is very dark. It is not a problem with a bad cable box or a bad DVD player, as the previous owner had the same problem. I am pretty knowledgeable with electronics and know how to solder electronics. Can anybody help at least narrow down what may be faulty ?

i have a red colar tube that developed a problem over night the pic. is warped beyound adjustment. the bottem third looks like a rolling wave of ghosting . I have removed the power, bled the capaciter off, leveled the lens and tube pack and removed the outer lenses. under the red convex bottom lens,(the one sealed in fluid), there is what looks like a film which i can see lookes like it is warped which explains the wave. My question is can this film, which appears to be flexible be replaced, and if so what is the fluid that i am guessing works like a coolant. and wher to get replacement fluid. Or do I have to just replace the whole tube. any help on this subject would be helpfull. thanx...

DANGER I take it you understand that these can kill. Even WEEKS after they have been unplugged. The chassis can be HOT on them too, what is normally considered to be EARTH can be live with thousands of volts. Bleed the capacitor down first, using the right resistors, use rubber gloves, boots and stand on a rubber mat. Keep one hand in your pocket to avoid current going through your heart if you mess up. This is just how I do it since a near miss. Check out precautions yourself, from a reputable source if you still wish to try. Now that I have said that, it may be connections on the inside of the Colourstream interface. Sounds like you have dropped a colour and have another problem that could well be related. ie: two wires touching or shorting.

My Toshiba 53HX71 takes about 20 minutes to "warm"

This is a symptom of poor solder connections inside the set. The set will continue to deteriorate until it won't turn on at all. This is essentially a labor only repair and should not be to expensive for any TV service shop. Once this has been repaired, the set should work for many years to come.

These poor connections are caused by the continual heat/cool cycles because of use and is normal.

Most of the time the Hyper Board failing is the cause of this problem. It will eventually get worse where it also affects the HD ins. Unfortunately the Hyper Boards are no longer available from Toshiba and have not been available for quite some time. My suggestion is to coast with it and replace the Set when the HD ins fail.

Sounds like a bad tuner/decoder on the Qam analog side of things. You can bypass this with a Clear qam converter box or a analog to digital tuner box or simply having this repaired upwards of $200 bucks.

No brightness for Colorstream either connections

Sounds like a bad coupling capacitor in the luminance "y" signal processor circuit. Use a schematic of the tv and a osciloscope to find this problem.
