Hello,
I have a limited knowledge, but I want to learn.
My SAMSUNG LE37B530 is causing me problems.
Most of the time when i start it, it makes a sound of welcome, then the red LED is flashing few times but the backlight doesn't start.
I'm saying backlight, because in the dark with a flash light, i can see taht the image is there, it is just not lighted from the back.
Sometimes, if i try several times to turn it ON and OFF, it will finally start, but it is more and more rare.
My Powerboard is a BN44-00262A, the main is a BN41-01165A.
Here are answers to question I saw in other posts:
I see no badcaps.
If I plug the tv on without the connector between the MainB and the PowerB, the backlight is turning ON.
and I read at the connector CNM802:
DET_5V = 4.6v
E_PWM = 6.8v
INV_ON/OFF = 1.6v
13V M = 12.5v
5.3V = 5.2v
13V S = 12.5v
STBY 5.3V = 5.2v
PWR ON/OFF = 0.8v
I_PWM = 0v
H_SYNC = 0v
CM804 = 15v
If i plug the TV on with the connector berween, PB and MB, I have WELCOME SOUND but NO BACKLITE and the following changes :
DET_5V = 0.3v
E_PWM = 3.2v
INV_ON/OFF = 5.1v
CM804 = 18v
I hope it is enough for you to give me some directions.
Thanks,
Cheers.
