Mitsubishi 55859 doesnt turn on only for seconnd green lamp comes on a click and turns off code 23 replced Q5A31 ( Horizontal Output Transistor 2SC5418) and Q5A01 (Horizontal regulator 2SC4690 ) and Q5A51 ( High Voltage Output 2SK2771 ) change caps so far and
The DM moduel ,Located on Left side of TV chassis has fan in or on side of moduel, If so inside DM is 4 capacitors
1000uf 16v replace them with 1000uf 35volts ,If you have 7 capacitors of same value Then replace all 7 caps with 1,000uf 35volt capacitors after replacing all capacitors then Press reset buton Hold for 10secs then Press Power.
I've run into that a couple of times that code does point to a board problem. However it can also be caused by a cold solder joint on one of the CRT deflection yokes (very often it is the RED CRT that has it.) you can try tapping gently around the yokes to see if set will power on and shut off.If you get a reaction that's your problem! Unplug set and get a closer look at the wires that are soldered at the yoke. You may have to loosen the yoke in order to get at the wires.If you can repair connection without moving the yoke that would be the way to go.Warning! If you have to loosen the yoke make sure you get it back in the original position as this will affect picture!!! you may still need to do a light touch up in the converegence as it is sometimes difficult to get it back exactly as it was before. Good luck.
