SOURCE: WS-55511 55in volume turns up by itself & can't switch devices

The remote is not the problem. The switch for volume up on the control panel has become leaky. Very common problem for this generation Mitsubishi. If you don't mind not having the control panel working you can disconnect it and the set will work just fine with the remote. To disconnect the control panel pull the speaker grill, it just snaps off, and remove the front access panel. Once that is done you'll see a cable going to the switches just disconnect it.

SOURCE: Mitsubishi WS-65809 - works, but screen won't power on.

yes that is correct 12 is normal...make sure all connectors are plugged in and in the correct places . conectors should be marked with letters that match the marking on the circuit board. Then look for heaters , in the glass bottom of the picture tubes(CRTs) there should be a little orange glow visable though the neck of the CRTs just above where the crt boards plugg onto the bottom. if the heaters are not glowing then check your wires to the crt boards again , you probly tugged one of them too hard during disassembly also check for cracked solder in the heater circuit......Oh yeah, you didn't mention -Does the TV get high voltage ??? thats important to having a picture......If you see the heaters glowing when the tv is on then look down into the lenses of the crts . If you see a brite color horizontal line closer to one side in each of them then you know most of the tv is working. If that line is curved then the tv probly detects that the convergence circuit is not working and it is blanking video.
OR -----
the error is 21 (see what number it ends the sequence with..) . Error 21 is X_Ray protect and you probly plugged one of the connectors into the diagnosic connector(near the high voltage transformer- normally nothing goes there) . If that is the case then somthing in the H.V. circuit could have been permanently damaged and now the tv has a new problem and wont work even if you put that connector in the right place.

SOURCE: I have a Mitsubishi WS-65711 that is six years

I have the same TV and replaced the convergence IC chip. It should be a single STK393-110. It's located on the middle PC board toward the front of the board (toward front of TV). As ladywinn stated, it is connected to a very large heatsink that nearly spans the width of the board.

Make sure you also check and replace any bad pico fuses. They look like resistors. Your TV should have a diagram on the inside of the case on one of the arms that holds the CRT assembly. Listed on the diagram is the approximate location of each fuse and their designations (something like FA005). The designations are also printed on the PC boards. Usually, 2 of these fuses are dead if the issue really is the convergence IC.

ONLY use genuine SANYO IC chips!! Just an FYI, don't buy the cheap chips or you'll be doing this again very soon and risk possible further damage.

Good luck!

SOURCE: how to reset convergence? on mitsubishi ws 55511,

There is an option in the user menu on the tv. Using either the remote or control panel on the front of the tv, press MENU then select SETUP. After you choose SETUP go to the 3rd column with the 3 icons. Here you can adjust the red or blue color or reset the convergence back to factory default.

After a few years the set will begin to show increasing problems with the convergence settings. When you can no longer adjust either red or blue horizontally or vertically an IC replacement will be needed. Your set uses (1) SANYO stk393-110 and you want to make sure it's SANYO and not a knock off brand as those usually fail prematurely.

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

Trouble changing device


Your problem may be solved by re-initializing the set. With the tv on use the remote and push MENU,2,1,7,0. A display will come up. Use the up down arrows on the remote to select INITIAL and press the enter key on the remote. That should do it.

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.

Press in together the menu button and the Device/input button on the set and hold them both in together for 5 seconds and see if the led will blink a two digit error code, then respond to this same post and let me know if it gave a error code and what the two digits were.
