The front power LED turns on, but no picture or sound.
Anyone run into this model before?

Re: This guy has an RCA 42PA30RQ
No idea... Elektrotanya gives nothing.
Just remember with a TV with "no power" fuses could be pulled and screen could be cracked - double check the LED does light as when my dad (no blame on him) forgot when picking one up, and got a cracked screen.
How much is it costing you?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
Hi i have the same model with same symptoms no picture no sound just a red led power indicator when power is pressed it turns blue makes clicking noise from relays and nothing after pulling off back cover pushed power button same clicking no picture and i noticed the logic board has an led and it flashes and the main power board has a light bulb next to the relays which does not light up notta nothing , if i disconnect the z board no changes if i disconnect the h board it does change the clicks to one click , after probing around with multimeter i found there are dead shorts on the main power board along with open circuts on one cap and a resistor and dead shorts on other resistors and several power fets show dead shorts but i have a hard time thinking that so many components failed all at once even thou its an rca its has samsung all over it on the inside along with another model number lol anyways i will post some pics thought maybe somebody has messed with this one before and know right off hand what it is........Comment

Re: This guy has an RCA 42PA30RQ
My problem started out with sparkles on the screen. I had OSD. I disconnected the Y main board to test for shorts or failed components. When I reconnected the Y main, the PS board relays just clicks and I get red LED light. When I power on the set with the remote, I get clicking and VS and VA does not show 207, and 54 volts. I also noticed the fuse located near the AC input has no reading. When I disConnect y main and I get two clicks from psb relays and 207 15 and 54 volts for VS and VAComment

Opps I meant when I reconnect the Y main board last sentenceComment

Re: This guy has an RCA 42PA30RQ
Try with Y-main connected, X-main disconnected.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 think I did that but ill go back and do it again. I didn't have this problem until after I disconnected connectors. And I tried finding the service Manuel for this set with no luck. I'll get back to you but if my memory serves me correctly, I had the same problem with the X main disconnected also. But I check it againComment

It's basically a cut-down Samsung PS/PN42B450.

Re: This guy has an RCA 42PA30RQ
Well I worked on this TV again. I disconnected the x-main with Y-main connected and I still get the multiple clicks. VA and VS are abnormal. I reconnected the X-main and disconnected the power cable to Y -main and I don't get the multiple clicks and Va ans Vs are 207 and 54 volts. The logic board has flashing LED. I checked the Y-main for short components and found none. I checks esr on the caps and cap capacity and they were all fine. What's interesting is on the power supply there are two fuses. I get no reading with The fuse on the primary side and the fuse is not blown.Comment

Re: This guy has an RCA 42PA30RQ
With a scope, you can verify the Y-main and X-main functionality. Do you have a 10X probe, and is your scope rated to 400V or more?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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...
