lcd tv TOSHIBA 32AV500P inverter board MPF3002 (PCPF0207 77C

[ANDRASONI]

I have this problem TV on the inverter module with the above code. It accepts the BL ON command voltage, but so much. Initial was defective Q50 = 2SK2837, after replacing it normally worked, then stopped with the current sound without the backlight . It is equipped with BD9766FV, FA5501A, 2904H212, RM601. The plate is quite "bushy", difficult to follow without a schematic. On somewhere I saw it would be equivalent to DPS-165GP (JQ10003), but it does not look like.
