MODEL MITSUBISHI HD1080 /WS55315 FRONT BUTTON SEEMS WISHY WASHY, MIGHT BE BAD?
SOURCE: Mitsubishi VS-50705, 50 inch Rear projection TV won't turn on!
most of the time the convergance ic go bad:
but try this:
The 3 flashes of the led when you plug the unit in is the
microprocessor initializing.
This unit has an error code diagnostics.
On the front panel of the unit press and hold the INPUT and MENU
buttons at the same time and hold them down for about 5 or 6 seconds.
The unit should activate it's error code mode.
The led will flash count the number of flashes. It will then pause for
1/2 or 1 second. The led will flash again count the number of flashes.
The unit will repeate this for about 5 or 6 times.
You now have the two digit error code. The first time the led flashed
is the first number of the error code, the next time the led flashed is
the last number of the error code.
12 ----------- indicates no error
21 ------------- X-Ray Protect circuit
22 ------------ Short Protect circuit
23 ------------- Horizontal Deflection failure
24 ------------- Vertical Deflection failure
Most units give a error code "22" short protect circuit. If so check:
Q5A00
C557
If Q5A00 check bad there are other parts that have to be checked or
replaced.
If you are able to do above call a tech to service the unit

you need to replace your convergence ICs. Post your model number of your set, and I will post the correct stk numbers and a link where you can get new ones.

Sorry for the late reply I just got up.
From what I understand of your problem it is most likely a blown capacitor or main IC. Unless I can open up the unit and test the IC's and capacitors I can not be really sure which is why I hardly answer questions about TV''s as they are hard to troubleshoot without the unit in front of you. Ive found a site that can help you via a service manual since I could not find the exact service manual for you from my manual book. The site also has the parts that you will need if ever im right and it is the capacitor or IC. As for the IC's by experience is hard to test without an Oscope but you can do it by gradually eliminating the problem, again you will have to refer to the service manual regarding that. By the way the capacitors I mean is the one that goes to the main module as that is what powers the controls for the TV. the green light is just the "pilot light" which means you have power to the TV but the power is not going past the capacitors to the main controls or the main IC. So simply put the problem can be the capacitors (Which is what you check first) if they are ok then look at the IC via using a service manual. You can use a multitester for the capacitor first if they are dead then just change them and you should be ok. Let me know what happens or updates ill reply to them as well.
