Re: 40" Philips 40pfl4706/f7 No Power
Good news. I got the power board, and after installation the TV works great. Well, the service center diagnostic was wrong. Thank you Tom very much, you saved me lot of time, money and hassle. They wanted to charge me $390 for replacing the wrong part. I got it fixed for only $35. I really appreciate your help Tom. Blessings.

Re: 40" Philips 40pfl4706/f7 No Power
Ok, i will do that. Is there a possibility that only the power board that is bad?

Re: 40" Philips 40pfl4706/f7 No Power
I checked online, there is boards for about $25. Do you think that I should take the risk and try to replace only the power board for now? I connect the TV to surge protector, I don't know how I got that. It was working perfect and suddenly turned into black screen.

Re: 40" Philips 40pfl4706/f7 No Power
Yes. it was disconnected. I used that cable end to connect the resistor and check the voltage. i still get 5.2 voltage at P-ON and 5.3V while connecting the resistor.

Re: 40" Philips 40pfl4706/f7 No Power
I just got the resistors today. I did the test, I shorted P-ON with the 5.3V (Pin #3 and Pin# 6 starting from the red wire) with 300 ohm resistor. I unplugged the cable from the main board and plugged the power cable, but I got NO voltage on the 12 volt pins!!

Re: 40" Philips 40pfl4706/f7 No Power
I am still looking for a resistor 100-470 ohm. Should I buy it? Can I make one, or how can I find it? Thanks

I don't have a resistor handy, but I will give it a try and let me know. Should I order a main board now, or wait for this test?

I didn't get any voltage on standby or even when I pressed the power button.

Re: 40" Philips 40pfl4706/f7 No Power
Yes ... I have both... I know from previous post to measure STB5.3V, I measured it on standby, and I got 5.2 volt. but I don't have other than standby since the system is not turning on at all.

40" Philips 40pfl4706/f7 No Power
Hi all,
I have an LED TV that died suddenly. It lost power completely. I tried the Remote Control and the power switch, getting no LED light or any response. The service center diagnosed it as a bad mother board and wanted to charge me $350. I think I can do this job by myself and save some money, but I am not sure which board is defective. It might be the power board or the mother board i guess. Any help is greatly appreciated.

Re: 40" Philips 40pfl4706/f7 Mother board replacement
Hi, I got the same exact TV, but my TV just stopped working. It has no power at all using the remote or the power button. Should the steps mentioned above work in my case? Will testing the output voltage help even there is no response from the TV at all? Thanks.
