Re: 40" Philips 40pfl4706/f7 Mother board replacement
Update - I received the new mother board today. Hooked it up and the TV works great! $70 for the new mother board. Not bad. The repair shop was asking for over $300 for the part and labor. Thanks again Tom!

Re: 40" Philips 40pfl4706/f7 Mother board replacement
I just placed the order for a new mother board. I don't trust myself to do a solid enough job of wiring the BL-ON to 12V.
Thanks for walking me through the trouble shooting! I learned a lot.Leave a comment:

Re: 40" Philips 40pfl4706/f7 Mother board replacement
Thanks again! I'm getting .005V on the BL-ON, .019V on NT_Dim, .005V on Ext_Dim and 24.94V on all the +24Vb pins.
The screen actually turned on for a moment when measuring these pins. I think it was on the blue philips screen.Leave a comment:

Thanks! I'm not getting any volts on P-ON or the P-ON12V pins in standby mode.
With the power on I'm getting 3.296v on P-ON and 12.23 on each of the P-ON12v pins.Last edited by muehring; 04-22-2013, 06:03 PM.Leave a comment:

Is this the legend you need?

The other connector's legend (the one connecting to the smaller board in the middle with the two red caps) is:

Great, thanks for the quick reply! I'll give it a shot. I did use my credit card's extended warranty. They cut me a check for the cost of the repair and I used that for a new TV. The mother board's not cheap, but if it works it'll be a good deal.Leave a comment:

40" Philips 40pfl4706/f7 Mother board replacement
Hi,
I have a Philips LED TV that stopped working after I installed a software update. I took it to a repair shop because the warranty needed an estimated repair cost and they said I need a new mother board. I found a replacement mother board online. I'm wondering if replacing the mother board is as easy as taking the old one out and putting in the new one. Are there any other steps I need to take after replacing?
I have hobbyist level electronics experience. I think troubleshooting the mother board would be too much for me since it's SMD.
Any help is appreciated....
