I have a Mitsubishi VS 45605 that won't turn on. The green light next to the power button, labeled TIMER, lights and immediately goes out, then blinks a couple of times and then goes out. It sounds like the TV is turning on and shutting itself off. I have tried unplugging and plugged it in again, same results. Any ideas of cause and cost of repair? It is seven years old and I had no problems with it prior to this.
This sounds like it could be a High voltage shutdown, a bean detection shutdown, a short in the sweep circuits, or a power supply issue.I have found 1. SHORT DETECT SHUTDOWN (PIN 13 OF IC700) CHECK FOR OPEN L902 PART # 351P155010 OFF Q904 C (15 V SUPPLY) ON THE MAIN PCB. 2. SHORT DETECT SHUTDOWN (PIN 13 OF IC700) CHECK FOR SHORTED D913 PART # 264P722010 AND OPEN Z901 PART # 283P039020 (Z905 AND Z900 M 3. CHECK FOR LEAKEY D5A21, PART # 264P045040, IN THE BEAM PROTECTION CIRCUIT ON THE MAIN PCB 4. CHECK PIN 6 OFF IC5A01 FOR 22.2 VOLTS DC IF LOW CHECK D5A09, PART # 264P244030 ON THE MAIN PCB. Or possibly the crts have leaked fluid and damaged the system or convergence board. It would be a total shot in the dark to say what is wrong with this set without looking at it. You are going to have to call in a tech to give you an estimate my friend. good Luck, and let us know how you made out.
Larry, Thank you for taking the time to answer my post. It is sad to say that without any knowledge of what could be wrong I am at the mercy of the technician. Like many others I think have been burned by technicians who either were dishonest or unable to correctly diagnose a problem on the first try. I do not see any leakage or discoloration on any boards. Any idea of price range on the repairs you listed. Don
Don, anywhere from 150 to 600 bucks. depending on what the problem is.
Thank you.
