Question about Mitsubishi WS-48513 48" Rear Projection Television

Blinking Green Light on Mitsubishi DLP 52525

I have had a Mitsubishi DLP 52525 for 2+ years now and recently the green timer light started to rapidly blink when the unit was turned on and it continued to blink without the picture coming on. After discconnecting the power and then using the system reset button, the problem remained. I swapped out the lamp and the tv worked for about a day and now the same problem is occurring. I have hit the system reset button but to no avail. There is nothing in the manual that deals with what is indicated by a constant blinking green timer led. Looking for suggestions. Just did the repair that Chris mentioned by changing out the 4 caps and no change. Plugged the set in and the green light on the front continues to blink. Hit the reset button and no change. Suggestions? Ideas ? This is on a 2004 WS-48513 Mitsubishi.

    Can you help me identify the Pico fuses?

    Once I find them just use a VOM to do a continuity test on them?

    Thx,

    Joe

    they are just small ceramic links solderd directly to the back side of the circuit board they are usually brown or black. They will be listed in the service manual by location so you can find them

the circut that detects the bulb has been also failing in these sets
and the conversion chip that controls the picture , and the transformers are not putting out the full power they are supposed to.
this set will need to be tested to determine the exact cause or causes

You most likely need the V26 DM repair kit at the following link, that usually repairs the blinking led problem.

The 52525 is definitely going to either:

1. have the caps on the FMT/DM board replaced (not something I'd recommend you do yourself)

2. have the electrical chassis rebuilt (as sometimes, you can replace the caps and still have the problem).


wait time: 4-8 weeks
cost to rebuild: $400-$500
cost for labor: $200-$400

the dlp will most likely need a qualified mits repair center to take over for you. repairing that set is pretty involved. and the parts you would need are not available to the public.
on your 48" CRT projection check the DM module for 4 vented 1000mf 16v capacitors. replacement should get you tv working great
