Will not reset green keeps blinking

You are experiencing trouble in the DM assembly. This is the vertical module on the left when looking from the rear. Most times, replacing 4 capacitors on this board (1000mf@16v, high temp) will cure the problem. Defective caps are bulged on top. Service center repairs can run from $200-275

Blinking Light Problem on Ws-55513

If bad capacitors are the problem then replacing them will involve soldering.

If the problem is something else less visible then fault finding will be difficult without the proper service manual.


This will show the correct disassembly and test procedures.

Good luck.

Mitsubishi LED keeps flashing green constantly

This problem happens on many Mitsubishi TVs, older CRT projections, and some of the older DLP projection TVs. The flashing LED means the TV is booting up, but it should stop in 90 seconds after plugging in AC power or resetting.

The typical cause for this is bad Capacitors (caps) in the DM module. 95% of the time its the caps, but could need a new DM module. Almost always the caps are bulged like in this picture:


They should always be flat on the top, if they're bulged, they're bad. In some cases they will not be bulged but will still be bad.

In almost every case, these caps are 1000uf @ 16 Volt caps, and should be replaced with 680uf @ 16 V caps @ 105c. The caps are always solder in parts.

In the CRT projections, there are 4 or 7 of them on the DM module that sits on the very left side of the chassis when viewed from the back of the TV set.

In the DLP projections, there are quite a few more, and they are on the FMT and DM board (4 each) and sometimes 4 will go bad on the power supply. The DLPs also have some larger caps that will go bad on the power supply causing a false lamp error.

In the case of the DLP caps going bad, Mitsubishi rebuilds the "Chassis" for service centers for about $250-300 + labor required. This is typically the recommended repair for these sets as they require extensive disassembly and mechanical skill to repair.

In the case of the CRT projections, repair is quite easier and can be repaired by people with some mechanical know-how and basic soldering skills.

For either repair, search the web and you can usually find a tutorial with instructions and explanations like the one found here:

Picture goes to verticle colored lines then goes blue screen tv s

This is likely capacitors failing in your DM or FMT module. This model is know for the 1000uf caps going bad after 4 years or so. There are 4 on each board, plus 4 on the power supply that may go bad. You can tell by the bulging tops that are not flat. Two 3300uf caps go bad in the power supply regularly as well. I recommend getting a service center to send the whole signal block or chassis into Mitsubishi for rebuild to get it all taken care of. The dissassembly is very difficult and frustrating. If you have tons of time and determination you could repair yourself.

Flashing power light tv wont come on mitsubishi 1080

If the tv has the continuous flashing led, you have a DM board problem. It is likely bad capacitors in the DM module.. there are 4 of them 1000uf caps that will go bad. They will get a bulging top on them when they go bad. . Mits recommends replacing them with 680uf caps with a comprable or higher voltage rating. The DM module in on the left side of the set (viewed from the back) and is somewhat difficult to remove.
