Mitsubishi Projection TV Won't Power Up
Greetings Gadget Gurus...
I've searched the archives but found nothing on the subject... I have a 1989 Mitsu projection tv model VS-5002R (51") that won't come on. It makes a clicking sound like it's trying, and will flash lines of color after several attempts, but something won't quite catch. The problem was intermittent but it now seems thoroughly cooked. A friend thought it may be magnet related but that's as much as anyone's been able to offer so far. Any clues/hints/thoughts/speculations/conjectures are appreciated. N. PS: please reply here - thanks! |

Get your ESR meter out and start checking all the electrolytic caps in the
set. Check out the vertical deflection and power supply circuits. "Not" wrote in message ... Greetings Gadget Gurus... I've searched the archives but found nothing on the subject...

Mitsubishi Projection TV Won't Power Up
This model suffers from vertical failure associated with a defective cap in
the power supply. A known failure mode and a kit is available from Mits to overcome this problem. There is also another problem associated with the horizontal driver transformer. You would be best advised to unplug the set and have it serviced before the CRT's are ruined from repeated attempts to turn it on. There will also be quite a number of leaky caps in different areas of the circuits that will need replacing to circumvent future failures. Good Luck, Bill Jr "Not" wrote in message ...
