Re: Sanyo FW42D25T
You have 12v marked on board at lvds connector. Need to trace back and find missing 12v

Re: Sanyo FW42D25T
Those are the voltages of the transistors UL1 and UL2 next to the plug for the LVDS cable.Leave a comment:

Re: Sanyo FW42D25T
T-con voltage probably originates off of main board through transistorLeave a comment:

Re: Sanyo FW42D25T
you should have 12v on the t-con fuse, but the lvds, d/pairs are only low voltage and you really need a scope to see the signal.
if you do not have 12v on the t-con fuse, disconnect the t-con and see if the 12v comes up.Last edited by attainteddragon; 10-04-2017, 04:06 AM.Leave a comment:

Re: Sanyo FW42D25T
Have you checked the two regulators UL2 and the one below it.Leave a comment:

Re: Sanyo FW42D25T
So I am trying to figure out why I would be getting no 5V or 12V or anything close to that coming from the PS/Main to LVDS output.Leave a comment:

Re: Sanyo FW42D25T
T-con fuse is good. My problem is that I am not getting any voltage other than low coming off of the main board to the LVDS cable except low voltage. I tried the PS/Main on another identical TV with same panel that has a bad board and it does light the screen.Leave a comment:

Sanyo FW42D25T
Hi all, working on a Sanyo that powers up and has backlights but no picture. I checked voltages from LVDS cable and I am getting the low voltage 1-1.4V, but no higher voltage. I'm assuming that is why I'm not getting a picture. Also I am getting the proper voltage on the main cap. Any help would be appreciated. Thanks.Tags: None

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?by Tynan DillI 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.

by HERETIK10Hi everyone,
I have a strange problem (for me) on an MSI GT70 2PE laptop.
When it's under heavy load, power goes steadily to the battery (for 2 or 3 seconds) then return to the charger. If I remove the battery it turns off.
The higher the load, the lower the voltage on the main rail. We go from 19.5V, PC connected to the charger but turned off (normal consumption of 0.06A)
On, when it draws 2A the voltage is 19.2V, then eventually collapses to 18.5V (and turns off) around 5A.
I removed the first 2 mosfets (PQ13 & 14) from the main rail, without noticeable change.... -
by Dani_2024Hi and thanks in advance for any input you might provide!
I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO
Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...5 Photos -
by rddubeHello friends,
Looking for some guidance here. The RAM voltage circuit on this motherboard keeps burning out PU301 which is a RT8231AGQW. Copy of the board with the burnt chip attached with some voltage measurements and copy of the schematics also included.
I think I've checked almost every component in the circuit, but when I change the RT8231, the laptop starts I have 1.2V on the inductor for about 10 seconds and then the RT8231 goes south and no more voltage on the inductor. All other voltages on the laptop are good, this is the only one conking out for a reason I... -
by HenkeI wondering if there are some usual faults regarding the PS_ON signal from main board to PSU board?
Where do i start looking?
I have standby light and the PSU is working if i connect 3.3V to the PS_ON pin on the psu board.... - Loading...
