Hi,
I have a Hitachi DV-PF4E VCR/DVD Combo unit which is dead - no power.
Last used and working ok about a year ago.
Then it has stood unused in the tv cabinet unplugged from the mains.
I went to use it this week, plugged it in and nothing happens, no display/lights, no response when pressing standby button.
Opened to check and fuse ok, ac supply ok, caps all look ok, other components & pcb look ok with no trauma visible.
Any cause for it to just go 'bad' by not being used for a year?
Thanks,
Mark

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 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... -
I have a Hitachi 57F710E rear projection set with a bad power supply board. I've tried to fix it with help from this forum as well as another one, but without success. Today I found a Hitachi rear projection set for sale on Facebook that looked just like mine. After contacting the seller I found out it was a 51F510. According to the service manuals my set uses a HA01312, POWER UNIT DP4X-DM_24W and the 51F510 uses a HA01313, U901, POWER UNIT DP4X_24W.
Does anyone know if these 2 power supply boards are interchangeable?
