37" Philips 37PF9431D/37 Won't turn on (2 fast blinks, 1 long blink)

[tieny]

Here's a Philips 37PF9431D/37 LCD TV I just got. Symptoms are, I plug it in and theres no LED light (not sure if this model has a standby light?)

When I press the power button, the LED lights up green for a second (relay goes on) and then the green goes off and the red LED light comes on (relay goes off).

It'll blink twice really fast and then blink once for a longer time, then repeats.

Opened it up, no bad caps (its actually filled with rubycon capacitors) I can't seem to find any labels for 5V standby voltages, or any labels at all on the connectors.

Does anyone have the service manual for this set? I'm not sure of the code it is blinking.

Wow, that's bare bones PSU! Try following the two cables over to where they connect on the other boards and see if they are labeled there. You can try searching elektrotanya.com for the SM.

That resistor fixed it! Replaced with a 100 ohm 1W resistor. I could of swore I searched the model here and didn't find anything before...

I find the best way to search badcaps is to use google's "site" method. For instance:

site:badcaps.net 37PF9431D/37

https://www.google.com/search?q=site...37PF9431D%2F37

It works a bit better than vBulletin search.
