Question about Sony KP-41T65 41" Rear Projection Television
I have a 1996 KP41S3U . When it comes on it led flashes 12 times. What fault does this show and on which PCB !. Somtimes only sound comes on to get picture I put it on standby then push a channel no , after another 12 flashes its fine.. (I have another KP41S3U that shows 2 led flashes Ithink its power suppy as its dead so I can pull pcbs from this for a swap). If you can suggest the correct board swap and the board is ok, ive read that the fault will still show until reset in service mode.How do I get service mode. Tried (5 vol+ pwr from stand by nothing). prg+ and prg- when held on the TV and power switch pushed after 12 flashes gives TT00. The only TT code that works is 13. This gives V2.00 50 HZ 07/06/1996. Can you help Many Thanks.
I dont think Sony has a "12" blink code, the highest (being in a newer set) is a "10", might try rechecking that, as for the code 2 that is an OCP, usually a shorted horizontal output transistor/Convergence IC's/High Voltage distribution block. My bet is the Block as HV tends to break down parts like that over time You must be careful when removing the anode leads as you can break the tip off or burn something up if not done right.
