Mitsubishi WS-65869 ws 65869 TV that went out when I was watching it. Now when you turn it on the green led turns on (you hear a relay click) then it light goes out after 2-3 seconds. Is this something I can fix or should I call in a specialist?

Replace the Capacitors on the DM board. You can get the WS55859 DM repair kit which covers your model from www.tvrepairworld.com which has the caps and the CD with repair instructions

sorry but u have bad dm3 board

It means the convergence IC gave up already ang needs a replacement. And also check the 5A picofuse in the power supply.

RESET THE BUTTON NEXT TO THE LIHGT 2-4 TIMES

Replace all 7 capacitors in the DM Module on the DM Power Supply Board. If it is similar to the WS-65869 and WS-65513 it will have a metal enclosed DM Module at far left of chassis, looking from rear. About 4 or 5 connectors, screws, and Module slides out. Take top shield off. Take good notes or use digital camera or video recorder to make re-assembly easy. These capacitors are 1000uf@16 volts. They always check good, just replace them! After re-assembly plug AC in and wait 90 seconds or more (green Timer LED will stop blinking), then press Power button. If Timer LED doesn't stop, look for small pinhole (System Reset) and press switch with pen or small screwdriver, then wait for green LED to stop blinking. Then Power On TV.

Try to press both the menu button and the input/device button on the set both in together and hold in for 6 seconds to see if the led will blink a two digit blink code, then let me know the two didgit code, and I will try to assist you. Please respond to this same post when replying.

my mitsubishi medallion tv wont power on.
all I get is a blinking light. How can this be fixed

Your problem is not shown on schematic, C9A60 (470 pf @ 1000 v) capacitor and check and see if F9A04 & 05 are open. If so then its off to a whole different area. Do you have an email to send Sch.?

Check for open pico fuse in power supply caused by bad convergence I.C.Get pro help-you have a good set to save.Remember--practice visual acuity technique!And,above all else,do no harm!!

They are little green soldered in fuses located on the center board (the one with the STK's on it) toward the rear of the set near the large transformer.
