Question about Mitsubishi WS-55511 55" Rear Projection Television

1 Answer

WS-55511 shut itself down while watching TV and won't come back on again. I tried unplugging and reconnecting, it goes through the reset (green light blinking). The convergence went bad and the chip was replaced couple of months back. The tech had mentioned that the voltage output from tubes are low and the TV may shutdown or something along that lines. Looks like this is what is happening. Replacing tubes are not an option for me. Any other options to consider?

After you turn on and green power light comes on and then goes out:

Press and hold both the menu and input buttons on the front of the set for at least 5 seconds and release both buttons.

Power light will blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it 4 more times.

Let me know what error code and I will tell you what it means. If this information told you something you did not know, rate this solution as very helpful as I do this here for free.

    1,2 BLINKS IS OF COURSE NO ERROR DETECTED. it means something is not triggering the error code--a lot of possible reasons for this.

    Unplug set, plug back and try it again--if you unplugged it before trying the test you will get 1,2--try again and let me know what it is.

    Tried that, it's the same sequence 1, 2. The TV is about 7 years old. As mentioned in the original post the tech who replaced the convergence IC did mention the tubes are dying and the TV will shutdown. Any idea how many hours these tubes/TV last? In my estimate, the TV has been used heavily - probably about 35,000 hours in the last 7 years

    hours do not matter with these sets, if the tubes were the problem you would have different code.

    You have Yahoo Instant message?

GET DIAGNOSTIC CODES


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

PRESS AND HOLD "device"(input) 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.

I have a mitsubishi model WS-55511. The green light keeps blinking. Have reset by unpluging and then pluging back in and holding the reset but for 5 seconds and press the power button. worked once, but...


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.

Mitsubishi WS-55511 Problem TV out - Getting only continously blinking green light on the front-panel


I 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.
