Your Solution to the WS-55511

TWO possible reasons for the blinking light:

1. The DM unit (caps and or fuses) are bad---no longer made and only (to my knowledge) PTS electronics repairs/rebuilds them.

2. Less likely but Possible: remove front speaker grill and inspection plate behind it----locate the two bundles of wires from front keyboard on set and follow them down and to the right---unplug both plugs and plug set in and wait 70 plus seconds and try to turn set on with Mitsubishi remote.

The blinking light is the DM trying to boot up--if set works with front keyboard unplugged---the tiny reset switch on it is bad.

If set does NOT work that way DM UNIT IS BAD.

Press and hold menu button front of TV untill it stops blinking then turn unit on.

See my reply to your last posting---The set needs The Stk-393-110 and whichever of the two pico fuses is blown replaced--I have instructions AND photos of what the fuses look like.

I have seen this only 2 times----you may be able to unsolder and remove the reset micro switch---you have to remove the whole screen to get at it---the micro switch board may not be available---the switches can be tested with a ohmmeter set to high end and of course should not have a reading across them--I bet the reset switch is bad--you can remove it and put the keyboard back---most of the Mitsubishi sets use the same type of switches--Only other thing is leave the keyboard disconnected and just use the remote.

Glad you found the problem.

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

had the same problem with the blinking light on the front of the TV and it would not power up. I read all the problems everyone was having and thought I was going to face a huge repair bill. The service guy came out, pulled off the front panel where the speakers are and disconnected the circuit for the front display panel. 3 1/2 minutes in my house, $90 service call. Apparently, when you give the TV too many commands at once, it's safety feature is to"shut down and lock up". He mentioned also that sometimes when these sets get to be about 4-5 years old, the wires in front can "leak" causing a shortage and then locking up the TV. I keep the circuit unplugged and operate the TV solely by the remote. Give it a try, what can it hurt!! Hope this helps.

You need the V21 DM repair kit you can get it at the following link that has all the parts and full detailed instructions with pictures on CD so you can do the repair yourself in about a half hour. Clearly illustrated just click on repair kits on the left side of the page where the catagories are. yours Is the V21 Kit. Heres the link.

these set have lots of bad conections and have a problem with two bad caps in the 9 volt reg curcuit one is right behind the reg

Error code 12 means normal operation. On these models we have found that a switch is sticking on the control panel not allowing the set to turn on. Disconnect the control panel. You will be able to use the remote on it. To find the plugs for the control panel: Remove the speaker grill and front panel, then follow the wire to the connection. Remember to unplug the set before putting your hands inside of it. Tell me how it went. Lead Tech
