Re: This guy has an RCA 42PA30RQ
Odd. You have good Vs, Va but no outputs from either board. Is control board LED blinking?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: This guy has an RCA 42PA30RQ
i only get good Vs/va when I disconnect CN 5000 from the Y-main...when I connect CN 5000 I get multiple clicks from the relay, humming sound to the x-main, and no Vs/Va from PSUComment

Ok I'll replace the Y board...I checked the Y-buffer per your video and it checked out fine..no shortsComment

Re: This guy has an RCA 42PA30RQ
One thing to check is if you get good voltages with X-main unplugged from Y-main.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: This guy has an RCA 42PA30RQ
what I don't understand is the initial problem with the set was spackling on the screen..I removed the Y-main to check for shorts and found none.when I re installed it, thats when I started getting the problem with the multiple clicking from the relay. So if the LED on the control board is blinking, does that mean the control board is fine?Comment

Re: This guy has an RCA 42PA30RQ
Blinking light indicates control board is running.
When you removed the Y-main it's possible you damaged it from ESD...Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: This guy has an RCA 42PA30RQ
You can adjust Yrr/Yfr on this set to eliminate that later. I have done it before on the PS42B450. (Same TV, different main board & badge on front.)Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Okay...thank you for all your help, I'll order a new or used/tested Y-main from ebay unless you recommend somewhere else?? I'll get back to you with my progressComment

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.

Hi all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

Hi all,
TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!
I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!
A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about... -
I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and... -
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...
