hi, Error code 2-2 indicates "Short Protect Circuit" problem in tv. Need to check pico fuses in power supply as one or two got blown due to bad convergence chips. Below is an exploded view of tv chassis, power supply and convergence area has been marked to give you better idea to look for pico fuses. Unplug tv from wall socket before to repair/check any thing inside tv. Hope these info will help you. Let me know if you have additional question. Thanks.
The most common reason for this is one of the 2 pico fuses that protect the convergence circuit is blown. Changing the fuses will not help! They are green in color and soldered into the middle circuit board and are F9a04 and F9a05----look like resistors but are 5 amp fuses.
chance if one or both are blown---you have to have someone change the
STK-392-570 convergence IC'S that this set uses----the IC'S can be
purchased on Ebay for under 14 dollars and the same seller sells the pico fuses 5 @ 2.95.
best thing to do here if you or someone you know is able is to unplug
the set and look for the fuses---middle board towards the back---there
are 5 of them and the two closest to the back of the row are for the
convergence IC----If someone checks them (like testing any other fuse)
you will know--if either or both is blown--the convergence IC got them.
I have start to finish, step by step instructions and photos of the fuses etc----If you or someone you know can solder and is handy--you may be able to do the repair yourself.
If not, shops usually charge 300-400 for this kind of repair in this set.
shutting down can be due to a blown fuse usually in the convergence section. the fuses are soldered in, with a voltmeter you can measure the fuses. if one is open then probably your convergence ICs are bad. about $250-$400 to have a field tech come to you and replace them. The other possiblity is a CRT (picture tube) fluid leak. this is more costly to fix, to check for a fluid leak pull the front lower panel and check for fluid on the chassis with a flashlight. I have sucessfully cleaning fluid from the chassis with electrical cleaner spray. after covering the chassis with a piece of plastic the set worked fine. A slow drip leak won't hurt the plastic, big leaks are another story.
hope this helps
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
