Awesome. I'll be fixing a lot. I'll be getting 15 Vizio's with bad caps a couple times a week. They're all 37"Comment

Re: Panasonic FM good for replacing bad TV caps?
Can you also use FM series on logic boards/main boards?Comment
-
Re: Panasonic FM good for replacing bad TV caps?
You can. But the usual culprit in the main boards on vizios are 1117 LDO voltage regulators. The tvs your getting that won't turn on, does the orange standby logo stay orage after you hit the power button. It seems the newer vizios are having corrpted eeprom issues today versus the bad LDO regulators of yesterday.Originally posted by Pentium4 View PostComment

Re: Panasonic FM good for replacing bad TV caps?
Most of them turn on, they just get stuck with the "Vizio" logo, and you have to unplug them to turn them off. It looks like some of the Jamicon caps on the logic board are slightly bulging.Comment

Re: Panasonic FM good for replacing bad TV caps?
If they turn on vizio logo goes white but can't be turned off unless the power plug is pulled from the wall would be a very likely candidate for bad 1117 LDO voltage regulator. Before you start swapping caps get a service manual and scroll down to the dc-dc converter flowchart and check voltages. These tvs could only need a 50 cent regulator.Comment

Re: Panasonic FM good for replacing bad TV caps?
Alright, I will. Just in case of a misunderstanding, the Vizio lights up white and you DO get a screen, it's fully lit up and bright, but it just says "Vizio" in the middle of the screen and won't do anything else.Last edited by Pentium4; 07-24-2012, 07:37 PM.Comment

Re: Panasonic FM good for replacing bad TV caps?
If its showing a vizio splash screen and freezing then it's probably not the regulators. What are the model numbers of a few that you have gotten?Comment

Re: Panasonic FM good for replacing bad TV caps?
I'll check in a couple minutes, thanks for your help so far! I don't have any 470uf 25V Panny's, would UCC KY series work? that's all I have on hand. they're taller and skinnier than the Jamicon's.Comment
-
Re: Panasonic FM good for replacing bad TV caps?
The KY series should be fine. The panasonic FM's have a higher ripple and a little lower impedance but either has to be better than the jamicons that are in there now.Comment

Re: Panasonic FM good for replacing bad TV caps?
It doesn't hurt to check the regulators regardless only because it is a Vizio. Checking the regulators only 10 minutes or less. Well worth the time, if you ask me.Originally posted by Mr Bill View Post--- begin sig file ---

Re: Panasonic FM good for replacing bad TV caps?
what regulators should I check? and all of these TV's are Vizio E371VL modelComment
-
Re: Panasonic FM good for replacing bad TV caps?
All the voltage regulators on the main board. Search this forum for "U33 Vizio" and you will find multiple hits with instructions on how to test them and verify they are within specifications. I might have one or two posts in the threads.Originally posted by Pentium4 View Post
Like I said, checking them is easy and doesn't take a lot of time.
This thread also talks about the corrupt eeprom as Mr Bill mentioned in post #11.
