Question about Projection Televisions
Offhand, it would seem that the unit's problem is either heat related or a cold solder/loose connection. I would discount the possibility of a defective component since if it so then the unit would not even open up.
Pls post back if you are contemplating on doing diagnosis and possible repair yourself. Should you venture a DIY, pls be reminded of safety precautions when working with electrical devices. Of course this would also require a bit of familiarity with electronic components and circuitry, use of a DVM and a soldering iron. Access to a service manual or at least a schematic diagram with voltage measurements would make the diagnosis a lot easier. Should you be uncomfortable going this route, perhaps your best bet would then be to seek the services of a qualified professional.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

The most common problems I have found in this model is solder joints going out in the vertical and on the driver transformer.
I would say the picture tubes are probably starting to go out by now and the technology is changing.
Look at the new sets. LCD and DLP are using LEDs.
Manufactures are beginning to equip their sets with ATSC tuners that bring in High Def. stations by using a pair of rabbit ears.
In a little over a year most signals must be High Definition and the government is supposed to send out checks for about 40.00 to help fray the costs of converter boxes to convert the older set.
So, my thoughts are, the set is about 17 years old. The cost of repari and the repair itself would be like putting a bandaid on it.
Capacitors by now are beginning to dry out and solder joints are starting to open up, not to mention that the picture tubes are getting weak and changing luminance and fading..
Most sets I repair at this age have future repairs.
Check out the new technology.
