Re: Samsung LN32C530 will not turn on. Standby light just blinks



Power supply is BN-00339b

I've got to the conclusión that the problem is low voltage on CP801. I haven't found any reference for what it should be, but concluded that it should be around 380 Vdc in normal operation. That conclusion comes from calculating what voltage should be on CP801 to have 2,5 Volts on pin 1 of ICP801 through RP801-804, RP817 and RP818.

So, the problem is that ICP801 is not working properly, as it is not boosting the voltage to what it should be. Next...

Re: Samsung LN32C530 will not turn on. Standby light just blinks

After further inspection, I turned my attention to the power supply as I found that when in fail state the PS_ON signL kept receiving positive pulses from the main board. Also I noticed that when plugging the power cord into the power supply with the main board disconnected, the power supply turned on as expected and mentioned before, but after few minutes it started to fail.
So, after forcing the PS_ON signal to 5V, the power supply starts ok, but fails after a few minutes. The problem is that the FSFR1700 stops...

Re: Samsung LN32C530 will not turn on. Standby light just blinks

I am having a problem similar, but maybe not exactly the same described here.
After being unplugged for many hour or days, my TV (LN32C530F1F) will turn ON and work fine, even for hours. After some time, it will turn off, and not turn on again. Also, it doesn't need to be working in order to enter in this fail state. Just be being plugged to 120VAC will take it to the fail state after some time. The time needed to switch to fail state goes from minutes to several hours, however it seems to be that, over the...
