I would think that there is a part that has become thermo sensitive to heat,
rather than the set actually overheating. The inside environment of a set can easily be up to 140 to 160 deg F without any problems. There are some components in the set that normally will run up at about 160 F. It is very common that capacitors in one of the circuits that is becoming defective. You should have it looked after before it shorts or opens, and causes other failures. Also, other types of components can go thermo sensitive with age and use. -- Jerry G. ===== "tlally" wrote in message om... Hello I have an Apex 43inch Projection TV. It seems to be overheating. After watching for a couple of hours the picture will disappear then reappear but with no sound. I've taken the back panel off and the problem seems to stop. Any help would be great.

Problem is that APEX does not have any parts or service support for their
products so many shops are a bit shy to get involved working on them. If you can actually get a good schematic for the unit then start checking the power supply, deflection, and protection circuits. Specific components for the set may not be available. (I actually work for a retailer that sells APEX brands and we return to the vendor if they fail under manufacturer's warranty).

Well, what if the original poster has kids or pets? I don't know about you, but I think having the rear cover off of a rear projection CRT television is certainly a liability, especially if you have children or a cute lil' critter around. Mains power will turn any critter into a crispy critter. - Reinhart |
