Green timer light blinking constantly, no picture

sorry but u have bad dm3 board

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

The capacitors on the DM board need replacement, thats a common problem it will work fine but if power is loss even for a minute the capacitor drain, then they cant recharge since they need replacement so the set will just keep blinking the timer light. Installing the V26 DM repair kit from www.tvrepairworld.com will usually repair that. The kit contains the Replacement caps and the CD with detailed instructions.

The color wheel needs replacing. Thats causing the whining and it will also make the lamp light blink.

I suspect the lamp area is VERY dirty as is the cabinet's filters and fans. This causes great stress on your tv and lamp. Take the time to clean all of them fully. Is the unit in a dirty area? or in a high temp area? DLP's dont like high temp or contaminated areas as they are NOT air sealed units.

Did you try unpluge from the wall, and repluging back after 10 min.
Also run the self diagnosis by pushing the menu and device buttons on the front and let me know the code?

Thanks

If you have a green blinking LED that runs continuosly, its the widespread problem of failures of capacitors on several circuit boards in the TV. Currently Mits is having authorized service centers remove the chassis and send it them for rebuilding. Its an expensive and time consuming repair.

You need the V21/V19 DM repair kit thats available at the following link, it contains the parts and step by step instruction CD so you can do the repair yourself. Its listed under their repair Kit category.

check the pico fuses on the reverse side of the DM , Just check them in circuit for continuity. let me know how you make out, and if you need any more advice lert me know

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
