Hope I can get some help. My ws-48313 just went out one day. Call a Repair man, He came out and took what i will call the "power board" for a week and came back today and tv still wont come on. Green light come on for a 10 sec. you hear a relay click and than it turns off. No pitcure no audio. Repair man said he was going to order some IC and be back when they come in. So i did a doignostic check an i got 12. Cant find what that means. Also he said he was going to replace three IC"S one was a mitsubishi and the others were sanyo is that right. From what i gathered there is only 2 IC. Any help would be quite helpful.
thanks in advance, Peter A. Trapino
12 means no errors detected. I believe your refering the the Convergence ICs. the two ICs are sanyo for the convergence, Not sure which other IC he would be refering too.
Im not sure what IC'S are but he pointed to three chips or modules looking things on the back section of what im calling the power board. Thanks for the info any and all help is appreaceaed. The board im talking about is the one all the way to the right that the wall cord plugs in to. Thanks again slinteriors.
You must of had deflection problems then, as the Convergence ICs arent located on the board you described. you have a V22 chassis CHECK FOR 12 VOLTS DC (AC-OFF DETECT) AT PIN 3 OF PC9A21 IF LOW OR MISSING REPLACE PC9A21 PART # 268P058020 ON THE POWER PCB.
