Hey TJVJR, glad you got it to work (hairdryer reflow huh
)Did yours do the exact same thing as mine?-
It Turns on for about 3 or 4 seconds sometimes a bit longer, just enough to see a picture of the logo , and promptly goes out.

Re: Funai LF320FX4F Power Supply Issue?
I sure didn't, It seems the voltage was correct for the momnent it was on, but I switched out the power and the main boards with "working" ones, tried disconnecting all the plugs and powered up each time also with no change.Leave a comment:

Re: Funai LF320FX4F Power Supply Issue?
Since the power supply seems ok, what should I check next the main board or? Not sure what I can check on there, I get a clear Funai logo for a few seconds and that's it.Leave a comment:

Mr
Sorry I haven't got back to testing it till now, family stuff and all.
I tested every thing unplugged and plugged in, (input & screen) and had power of 10.9v on two diodes and 6.5v on the other two at all times. I also (a week ago) went and bought a cheap used power board because of the problem with the previous reversions of it, and of course it does the exact same thing.
Powers on, power light flashes 17 times, I see the Funai logo and...nothing steady power red light, no pic. It seems to be picking up a video signal with a HDMI hooked up...Leave a comment:

Once D608 is out of the circuit it seems fine, D654 looks ok too. No other diodes test bad on the board....Leave a comment:

Re: Funai LF320FX4F Power Supply Issue?
Didn't see any other shorts, I'll do test again after work.
D654 is a Zeiner, but it shouldn't be conducting both ways (leaking) with an lcd meter diode test should it?Leave a comment:

Re: Funai LF320FX4F Power Supply Issue?
I was going to post a picture and I can take one but the [URL="http://www.ebay.com/itm/Funai-LF320FX4F-Emerson-LF320EM4-LED-TV-Power-Supply-Board-BA3AF0F01023-/171343304392?pt=US_TV_Boards_Parts_Components&hash=item27e4db56c8"]Ebay zoom picture [/URL]is better probably than I can take.
It's identical, nothing burnt or discolored on mine. I can post a pic of top and bottom when I get back if needed, a quick test I believe, shows D608 (by the big cap) to be shorted. The fuse (F602) tested good.Re: Funai LF320FX4FLeave a comment:

Funai LF320FX4F Power Supply Issue?
Hi,
I'm the pround owner of a Funai LF320FX4F $98 Black Friday Walmart Paperweight. It Turns on for about 3 or 4 seconds sometimes a bit longer, just enough to see a picture, and promptly goes out. I assume it's the power supply PN# BA3AF0F01023.
I could order one off of ebay for $20 but where is the fun in that. The board has nothing visibly wrong that I can see, and of course I can't find any trouble shooting schematics for this thing. Any ideas on a good place to start? -

Long time lurker, fixed quite a few tv's. Need help with an oldie and don't want to spend $50 on new power supply for a maybe.Leave a comment:
