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.

jordan:
Resolder Q-51 and R-51
Check:R-91,R-92,R-93,R-94 (all 39Kr on inverter board)
Check C-53 (120uF/450V)
Check R-67,R-68,R-69,R-70 (all 390KR)

ANDRASONI:
Thank you very much.  mr.Jordan, I'll try!

ANDRASONI:
I checked and resolder all the mentioned ones without success. The RL01 does not work. The original Q50 transistor was 2SK4107 and I replaced it with 2SK2837, it worked, could this be a problem? I compared the catalog data and a little different Ton-Toff,in the rest 2SK2837 is superior to the original. Thank you once again mr. Jordan for involvement. From Romania, all the best!

ANDRASONI:
It resolved, I missed the R94 and R70 :c017: Mr.Jordan
