SOURCE: Mitsubishi turn on then turns off
Your model has the V22 chassis when it blinks a 21 cide which is what yours is indicating that maens the set is shutting down due to xray protection. Which means a votage is raising which trips the xray protection circuit and keeps your set from operating
1. SELF- DIAGNOSIS INDICATE X-RAY. CHECK FOR PROPER SEATING OF CONNECTIONS TO AND FROM THE HIGH VOLTAGE BLOCK. 2. SELF- DIAGNOSIS INDICATE X-RAY. CHECK FOR A SHORTED IC5A03 PART # 270P704010 AND AN OPEN R5A73 82K ¼ WATT OFF PIN 2 OF IC5A02 ON THE MAIN PCB. 3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB.
SOURCE: Mitsubishi WS-55857 won't turn on
Thank you for posting your concern details however i would be needing few more details from your side if necessary and allow me few mins to come up with the resolution.
SOURCE: i have a mitsubishi 1080 series wt-42311 model
i have a mitsubishi 1080 series WS-65315 model i power it on and led light turns off after 2 seconds
SOURCE: Green light comes on then goes right back off.
The TV indicates an error code 22 (short circuit protection). Check 2 STK392-570 convergence IC for shorts and 5amps pico fuse for open. I usually replace both STK's.
SOURCE: Mitsubishi ws-65809 powers on for 2 seconds.
2,2 error code is short protection---98% of the time it means one of the two soldered in pico fuses this set uses is blown----there are several---but your problem means if it is ws-65809 one of the two stk-392-570 convergence chips has failed.
I will attach a photo---they are on the middle circuit board and the two to the right are for convergence--both are green and 5 amp--with the set unplugged check both of them like any fuse--no reading means bad.
If you find this--I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS SET--SHOPS WILL GET 300 or more but you if you can do it yourself buy everything you need for under 40 dollars--I can tell you the best place to get the chips, fuses, etc.
If you want the instructions let me know and I will post them here for you---they are based on my own actual experience doing this repair in this kind of set hundreds of times.
If this information helped you rate this solution as I do this here for free.

Here is a photo of what the two chips look like--The one in the picture says 392-560 but yours uses two that look just like it--STK-392-570.
