Seisco RA-28 Control Board
This board has blown triacs and what appears to be caps. But when googling the part number I'm not getting an accurate part description or replacement suggestion. The markings read ( VRM .01k630v ). There are 4 on the board, next to the triacs, 2 are blown. I have found the triacs and ordered them but the blue caps or voltage regulators have me stumped . If any body can help with identifcation and suggest replacement parts my sister an brother an law would be grateful ( showers in 60 degree water is no fun from what I here ). Thanks ahead of time for any help.

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 folks,
I'm new to this forum. So my trusty 17-year-old LG 47" LCD recently died. As I was booting it up, I heard a hum followed by a loud bang, sounds of pieces flying around, and loss of power to the unit. Inspecting the PSU, I saw two obvious problems: a blown thermistor (bang + flung pieces) and a visibly bulging main cap. Inspecting as many components as I could with my Fluke MM, I diagnosed that the following components on the "hot side" of the board were also bad: one of the 2 main MOSFETs, main 8A fuse, small cap (25V 47uF) connected to main caps, and a blown... -
Hi all, I just want to share the repair of my 60PK550-UA TV set.
The TV set was powering on, just no image. After verification, nothing wrong on the YSus or ZSus boards. Nothing wrong on the main board either.
But I noticed that the LED was not flashing on the Logic Control Board. This is an EBR63450301. The LED is supposed to flash even with all the flat cables disconnected, with only the power cable attached.
All the voltages measured at the electrolytic capacitors on the board were good. From top left to bottom right:

I have been having issues with this garage door opener for a while first the range of the remote was a lot less and sometimes it would start to go down and stop for no reason that I could find and would every once in awhile to start with then it started going more frequently until last Saturday when I opened the garage door it refused to close so I cranked up force all the way maximum limit this did not work also the sensor on one side that has a green and red lights that are supposed to be on when the door is open and there are no obstacles in the way on the original board the only light that...

I am looking at the option of replacing my control/driver board to one with HDMI and/or Display port input on a 2K LED (I think IPS) screen.
The display is Samsung LTM270DL07.
I have tried using the model number to search for a compatible control/driver board but so far my efforts have been futile.
I am looking for inputs on what board could potentially be used for my display.
Attached are pictures of the display label information and connectors (CON30 CON40 only) and pictures of the current control board.
Also attached is a technical...03-14-2023, 08:52 PM
