Re: Philips 50PF9431D/37 - 12 VDC loaded by SSB

Well, the fun is over...

I gave-up on looking for the IC's after finding the mosfets with almost a 30 day lead time and the a minimum 2500 piece order for the other. I finally just bought a used SSB for $79 on Ebay. I had to set the option codes (so that it used my 50" screen instead of making it 42") and update the user software section. The only minor issue is that the values for the original TV are still stored (serial number, hours, etc.). I'm assuming that these are stored in partition 0 which I could...

Thanks for the help PlainBill. Sorry I didn't think about the chasis number/append issue.

I'll keep you posted on how things go.

By the way... the SSB P/N is 310432845251.

Hi everyone!

I have a Philips 50PF9431D/37 (free from my brother) with the low 12 VDC error. This problem is very similar to the one PlainBill had back in February of this year.

I have isolated the problem to the SSB...The 12 volt supply is around 5 to 6 volts for a few seconds during the initial power check which is then followed by the error/protection mode. The supply is at 12 volts and stays on whenever 1M46 is disconnected (12 volt connection to SSB from power supply).

I don't have a schematic and WOW components just keep getting smaller on these...
