Mitsubishi digital projection tv WT-42313. When I was watching a program, it turned off. When I clicked it back on it immediately it clicked back off. Any ideas? Nothing was in the troubleshooting section.

Mitsubishi WT-42313 TV


I found the schematic (downloadable PDF) for $7.99 at http://www.completeservicemanuals.com. Cheapest I found and highly recommended.
The blown fuse was due to a fried convergence IC. There are two of these on the high voltage board; they should be replaced together as a matched set. The bad one had gotten so hot I only had to unsolder three pins -- the rest were already loose!
I found the ICs at http://www.electronic-repair-kits.com, also highly recommended. The correct part for the WT-42313 is STK394-250. Make sure you order a pair and they will send you a matched set.
My set is now operating; I just need to clean the optics and do a convergence alignment.

Turning on my tv set


Same issue - our successful fix, at least temporarily, is to unplug power cable from outlet for at LEAST 4 hours...pref. overnight.

Mitsubishi WS-65511 Rear Projection Big Box TV resets with a green flashing light every 5 minutes, Then works fine for 5 more minutes (perfect picture). Acts up worse when cold. Warm it up Works hours It's NOT the DM board caps. I've already replaced the DM caps twice. Not the problem. No repairman will look at the set. Too Old. So am I. I could repair it with help. The power supply must have a safety circuit that will shut down & reset if too much draw. I DON'T have a diagram. I'm not sure how to trace it . Which board? If I unplug boards one at a time, Will it damage other boards ? I know it is NOT the 7 DM board caps everyone keeps telling me. I see no burn't parts, No bulging caps. Tapping on components doesn't reset. What kind of component would act up when cold , But not overdraw when warm? This set has the best beautiful picture when it runs. If you can get past the resetting every 5 minutes for the first hour, You can watch it sometimes for 20 hours. I've left it on at night & it is still on the next morning. Change the channel Or raise the volume, And off it goes. Once or 10 times, Keeps resetting. Then on for 4 or more hours, Maybe. I can't afford a new one. It works GREAT ! when it works. I've notice that even when the set is turned off, The green light starts flashing (resetting itself while it's off) , Then stops. Once in a hundred times it will kick off the breaker & you need to push reset with a pin on the front panel next to the green light. It's probably a 10 cent resistor OR a $ 1.00 cap. If I only had someone with more knowledge than me to help. I know how to use a meter & read a schematic. I built a Heathkit 25"TV in the 70's & all my novice ham gear. I'm 64 & not familiar with digital circuits. Can someone help PLEASE ?
