Re: Vizio E701i-a3 Backlight issue
I plugged in the replacement LEDs in the place of the original ones and they light up and stay lit unlike the original which would seem to prove that one of the LED strips in the TV is faulty. Just not looking forward to disassembling the panel.

Re: Vizio E701i-a3 Backlight issue
I purchased replacement led strips (all 3) and they tested good when I hooked them up. I am a bit nervous about disassembling such a large panel assembly. Has anyone done this or have access to the instructions on how to properly disassemble and replace. This is one time that I would prefer some instructions than figuring out being that it is such a large panel. Thanks again for your input.Leave a comment:

Re: Vizio E701i-a3 Backlight issue
I was afraid that might be the case.......just hoping that it could be something else.....makes me a bit nervous taking a panel apart. Like a bull in a china shop.....lol. Thanks guys, appreciate the input.Leave a comment:

Vizio E701i-a3 Backlight issue
Thanks for looking. I have a Vizio E701i-a3 tv that when turned on the backlight comes on for a second or so and then turns off. I do get an image when shining a flashlight on the screen (the message says RGB signal not detected, TV will power off). Another note, the backlight goes out while the Vizio logo is present after TV power on. I have replaced the power supply board with the same result.
This TV has three pairs of wires that power the LEDs. Since I do not have a wiring diagram, the only thing I could do is to remove each pair, one at a time. I still got the same result,... -

Re: Samsung PS-507-phn
The numbers in that document don't macth the numbers on the board I have. That is why I hesitate a bit. I truly appreciate everyone's input thus far.Leave a comment:

Re: Samsung PS-507-phn
Selldoor, yes, indeed I did. It appears that they are 680uf but never found the actual voltages, so I guess 25v/35v may be acceptable.Leave a comment:

Re: Samsung PS-507-phn
I guess I can try to locate some 680uf 25v or 35v caps 12.5mm x20mm and give them a try. Should these be low-esr caps?Leave a comment:

Re: Samsung PS-507-phn
randtek, we know the caps that were there were swollen and bad so we are going to start there once I can identify the caps. Problem is the tech that removed them no longer works for that company.Leave a comment:

Re: Samsung PS-507-phn
It came from a Phillips plasma tv (not sure of the model number). It is a Samsung board (power supply). Indicates Model number PS-507-PHN. Other numbers on the board are LJ41-05253a and LJ92-01511aLeave a comment:

Samsung PS-507-phn
I have a power supply board with the above part number. It is missing 4 caps (last person to look at it decided to remove them and never replaced) Can someone confirm what the values and voltages are for caps DC8524, DC8404, DC8405, and DC8407. The only clues I could find was 680uf (from a foreign forum that I couldn't translate) and probably a 12mm diameter cap (from a visual inspection of the board)
Any help is much appreciated.
