Question about Mitsubishi WS-55513 55" Rear Projection HDTV
Tv shut off, green light blinking, won't reset. read about a similar problem from someone else troubleshooting. told to replace the 4 caps that sometimes bulge. question is, is how do we find and replace the 'caps'? where are they located on the tv??? would be greatly appreciated, don't want the $300 minimum bill for taking it to the repairman.
I held menu and device for about 10-15 seconds on my WS-55515 and the blinking went away and my tv works just fine after that

Just had the tv repair man come look at it and he replaced the dm board to see if it would fix it and it still wouldn't work. After checking some voltages he is suspecting the E2P PCB. Charging for a cleaning, basic alignment, and install on the EEprom. $225 is the cleaning and alignment necessary or is that part of having the service. never really asked if i wanted it or not just included it?

1. Check for no 8.4 volts DC at pin 3 of PC9A10 on the Power PCB, if low or missing replace PC9A10 part # 268P058020. 2. LED does not blink at plug in. Check for 3.3-volts DC at connector RF pin 3 (system reset) if low or missing suspect the reset switch S7L20 part # 432P109010 on the Control PCB. 3. LED does not stop blinking after plug in. Verify the standby supplies, 12-volts at connector KA pin 17, 6-volts at KA pin 18 and the 28-volts at KA pin 19, if the supplies are present suspect the DM PCB part # 934C067001 4. LED does not stop blinking after plug in. Check C9B01, C9B02, C9B10, and C9B11 (1000 UFD 16) on the DM PCB, if they are bad replace them with part # 181P734030 (680 UFD 16 V). 5.

You have to replace the faulty capacitors on the DM Board.. Even if you have some experience in electronics a service manual should prove very handy.. Its got full schematics and how to guides so that if you just have minimum knowledge about using a multimeter you can fix it yourself..
