Re: Sony Bravia KLV-32v550A Blinks 8 Times
I have checked almost all resistance on board,
it reads INR-ERR Reads 0.55 volts
Backlight ON reads - 0 volts
Dimmer reads - 0.86 volts
Backlight is coming from ic5502 (MB91F313APMC-GE1) pin 78 and it reads 0 volts on ic, does it means ic is defective or ic is not getting input volts?
what should i do now??
Please suggest.Leave a comment:

i have connected standby 3.3V to Pin 29 (Pin 29 is still connected to board, i have not lifted it) and after 2-3 minutes picture freezes and tv itself switching on and off most of the time backlight fails to turn on...Last edited by pawangulati; 08-14-2015, 04:12 PM.Leave a comment:

Re: Sony Bravia KLV-32v550A Blinks 8 Times
I double checked IC5502 pin 29 reads "0" volts
10 Blinks is DIGITAL FE/DE error (in self test it says DTT_WD)Leave a comment:

Re: Sony Bravia KLV-32v550A Blinks 8 Times
IC5502 pin 29 reads "0" volts even when tv is working properly,
Now tv also sometimes goes to standby with 10 blinksLeave a comment:

Re: Sony Bravia KLV-32v550A Blinks 8 Times
Hi
8 blinks error back
tv worked fine for one day
Main problem is if we switch off power and back on after few hours it immediately goes to standby and 8 Blinks.
and i switch on again and after 2 or 3 attempts it switches on and work fine.
i have removed IC7301 (CXA3785R-T6) problem is still the same.
also there is some issue with color, after approx 2 hours of use colors appears yellowish.Last edited by pawangulati; 08-14-2015, 12:35 PM.Leave a comment:

I have lifted pin 44 of ic IC7301 (CXA3785R-T6) problem is still the same, 3.34 volts drops to 0 volts on pin 43 and tv goes to standby and 8 blinks....Leave a comment:

Re: Sony Bravia KLV-32v550A Blinks 8 Times
Pin 43 reads 3.34 volts DC and drops to 0 before tv shuts down, when we turn on tv it reads 3.34 volts and within few seconds it drops to 0 volts and second later tv goes to standby mode and 8 blinks.
pin 44 reads 3.32 volts in standby mode and drops to 0 when we turn on the tv.Leave a comment:

Re: Sony Bravia KLV-32v550A Blinks 8 Times
Yes i'm sure its same BA Board as of 550A
as i have already removed IC7201 there is no signal at pin 44,
do i need to solder Diod - D7204 which was removed by mistake and misplaced?
so should i remove IC7301 (CXA3785R-T6 ic) also? will doing so bypass the protection??Leave a comment:
