Mitsubishi WT-46809 will not turn on and stay on

When turning on my Mitsubishi WT-48609 it will turn green for about 4 seconds and then turn off. When pressing the input and menu together for five seconds it flashes me a code 22 or according to another post a problem with the short protection. Can you please give me suggestion on how to fix this or what I should order? It just started doing this a couple of days ago. Thanks.

SOURCE: MITSUBISHI WT-A42 ERROR CODE 22 "SHORT PROTECT CIRCUIT"

error code 22 is a short protect circuit. this means the tv has found a problem in the tv and will not let it turn on till fixed. this could be several different circuits in the tv that is causing this. we need to test some parts to see what this is. the most common is a shorted convergence circuit. a repair on this would range around 400.00. You should check using a multimeter and also you should be good at soldering

PS:I strongly advice if you don't have experience in electronics then better leave this job to a tech

Mitsubishi wt-46809 not turning on


Your convergence amp ICs have most likely failed and that will shut the TV down. You need to replace both convergence ICs they are both STK392-570 you can get replacement ICs with free instalation instructions at the following link.

Mitsubishi WT-46809 Turns on with Power light then turns off


there are 2 fuses -24v and 24 v normally would go out because
covergence ics failled . That would be a shutting down problem cased by missing those voltages.so you would need to replace those 5A (small green fuses) , you would need some kind of soldering and unsolderin skill) and the ics are stk392 570.two also. open the set from the fron ,taking speaker grill off and then the wood board behing (4-6 screws) you the the board in the center big metal heatsink. you would need to work from the back to repace those puppies.hdtvman

Same TV, same problem. I'll be watching for an answer. The dealer says it is old and outdated and not worth fixing.
