Question about Mitsubishi VS-4543 45" TV
Listen carefully, if you turn on and it goes off after 2 seconds, you need to change f902 and check q05a00 for short, if shorted, replace it, and then check for 130v and 34 v on transformer, if they are present, your problem has been solved, if you turn on the tv and hears little clicks, replace the optocoupler of the power supply. i did it and got my tv back on again!!!!

Check for opens at convergence ic's, if none replace stk391-020e's with new lead free sanyo drivers or just trouble shoot them.
