Re: How do you troubleshoot this board? samsung hps4253 BN94-01081A
when I jump to ground PSON Relay Clicks on and stays on and voltages are there, then when I jump VSON to STBY 5v Vs are there.
How do I test regulators? or is there a post somewhere on how to properly test them... I have a Scope if that is easier. Thanks once again Tom

Re: How do you troubleshoot this board? samsung hps4253 BN94-01081A
Connected with resistor powered on like you said and I connected the resistor to the high-voltage They check out. Can these boards be fixed? I would love to if it is doable
also will be uploading video cause it turns on intermittently watch and see If it helps. I'll post it in a bit

Re: How do you troubleshoot this board? samsung hps4253 BN94-01081A
From PSU
VA's 65v
VS's 200v
Stnby 5v
VT 33v
From Main Board
CN101 pin 6 fluctuating it should be 18v
CN102 Normal
so is this PSU problem or Main Board problem? is there a way to turn on PSU then check Voltages?
Thanks TomLeave a comment:

Re: Blowing Fuses on this...
How do I check if Power board is culprit? how do i trace it down? cause if it is blowing fuses on Y-sus doesn't that mean it is putting out to much from Power board?
Fuse that keeps blowing in attached picture...Last edited by NicoNico; 09-16-2013, 03:55 PM.Leave a comment:

Re: Blowing Fuses on this...
it is Z-sus sorry going from pic i found on my travels
this is what i am looking at... not my pic but same setup
Puff came from right Z-sus board near bottom
PS= Power Supply
Y = Y-sus
X = Z-sus
M= Main
L= Logic
A, B, C, D = connectors...Leave a comment:

Re: Blowing Fuses on this...
also saw a puff of smoke come from Z-sus board when i unplugged Z-sus board... and turned it on... am i wrong but how does power get to Z-sus board? isn't it from Y-sus board?Last edited by NicoNico; 09-16-2013, 12:28 PM.Leave a comment:

Blowing Fuses on this...
P50HDM Vizio Plasma with LG boards...
took a quick video of symptoms... [url]http://youtu.be/CwHbEXCOhFE[/url]
D15 comes on
D17 comes on
D1 Comes on then shorts out and relay turns off
Main board light stays on.
I tried a few things from this forum...
[url]https://www.badcaps.net/forum/showthread.php?t=25596[/url]
no fuses were blown when I started.. now on Y-sus board fuse keeps blowing fuses... help?
it sounds like a short near the top left PSU near transformers... Thanks Guys......Last edited by NicoNico; 09-16-2013, 09:49 AM. -
Re: Vizio VU37L HDTV10A Blinking really fast Orange Light
I just bought a new powersupply.. since i wasn't sure if the resistor was correct so.. sold it... and bought a P50HDM for 50... starting another thread...
not liking what i am finding out about this model...

Re: Vizio VU37L HDTV10A Blinking really fast Orange Light
C206 = 572 ohm - reversed = 0
C208 = 617 ohm - reversed = 0
IC201 = PBLW 23006Leave a comment:

Re: Vizio VU37L HDTV10A Blinking really fast Orange Light
i threw a resistor i had on hand that was close to what i thought it was.. :/ still learning... so photo of Burnt resistor is what i need to replace... sorry about the confusion...
i don't have a ESR meter... so i just was looking for leaks and pops.. is there another way to check caps without ESR meter? i have multimeter just haven't needed ESR yet
Checked burnt resistor reading was 1300 ohms -/+ 20
Thanks for the help guys/gals...Leave a comment:

Re: Vizio VU37L HDTV10A Blinking really fast Orange Light
changed fuse problem still there... Checked voltages on power supply and it is putting out 2.5 where it should be 5vsb no 24v or 12v... hunted for bad caps and didn't find any that were obvious... then found a burnt resistor and diode that has continuity both directions but the resistor is burnt how do i find out what it is? is there a way?
Thanks for all the help so far... you guys are really great
If you want more info just let me know...

Vizio VU37L HDTV10A Blinking really fast Orange Light
Hey first post..
Vizio VU37L HDTV10A
I had this given to me... it doesn't power on just blinks the moment you plug it in... i checked the fuses and F2 was bad F1 is good so ordered that... but what would cause it? where do i check next that might of caused this? guidance would be really awesome... I have the service manual from this site so.
Thanks in advance..
Nicolaus
p.s. i ordered 10 so i will be trying to just replace fuse to see if that works but i doubt it let me know what you Sparks think
p.s.s. the attached...
