Re: Voltage level on LCD power supply board.
I will go grab another one.. I think I have a crapsman in the camper

Re: Voltage level on LCD power supply board.
Ok ... One of my probes wasnt all the way in the meter when I tested the big cap.. It is testing at 440.... I also double checked my other readings and sad to say they are still jacked up.. And yes i had red to + and black to - and did go ahead and change battery just in caseComment

Re: Voltage level on LCD power supply board.
Ok I will check and see what I have and what I need to order... Need to get rid of these kids first GrrrrComment

Re: Voltage level on LCD power supply board.
A little, but they usually rarely fail.
It seems others have fixed this PSU by replacing it, so, go ahead and get a new one, its a 47n 1000v capacitor. If you want, you could use a 1500v cap for some extra headroom (perhaps that is why the 1000v ones got bulged?).Muh-soggy-kneeComment

Re: Voltage level on LCD power supply board.
Those caps can and do fail and bulging like that is a common sign something is wrong.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Voltage level on LCD power supply board.
Just got done shotgunning the board with caps.. And its still jacked up
Boards connected -------- not connected
5v-m=5.0 -------- 6.1
5v-m=5.1 -------- 6.3
sw= 15.4 -------- 100+ and climbing
BR1= 2.7 --------- 100+ and climbing
12v= .09 -------- .02
12v= .09 -------- .08
5v-s= 4.7 ------- 4.8
5v-s= 4.7 ------- 4.8
Stb= 2.09 ------- can hear a click when testing and reads 0..Comment

Re: Voltage level on LCD power supply board.
The Tv is stuck in Standby still,, But When I stick my +probe in Stb it kicks it off.. grrrComment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board
After all of... -
I want to know if I could hook up a solar panels to this boost converter would I have any issues doing and I would have issues what would they be

I was working on this CNC machine today found no keyboard functioning no control relay powering on
The screen powered on and was giving an operation error but the manual was not very clear about what the error exactly was but with a little bit of troubleshooting and finding out that the control relays not powering on and no keyboard functions we narrowed down to this one switching power supply which of course does not have any indicator LED light they are on the keyboard interface/relay controller board
Found shorted diodes on main controller relays there are 3 of them that... -
I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...
