Hello, I'm new to the group and to trying to repair a LCD TV. During the past few years, I've been collecting/repairing/restoring vintage personal computers (Commodore, Apple II, Atari, TRS-80, Texas Instruments, and Timex Sinclair). This has been my retirement hobby. Now I've gotten interested in trying to repair a LCD TV that I have and used regularly when working on vintage computers.
The LCD I'm working on is a Insignia NS-LCD019. I've downloaded the service manual that I could find, but it must be a different revision since not too many items in the service manual match the TV... -
Hi,
I'm facing this issue since this morning. When I try to power it on, the CAPS lock light flashes 7 times (or 6 if not counting the first one when the power button is pressed). The charging light is always on as if the laptop was connected to the charger. The issues started gradually where it would flash the light but after trying multiple time it would power on. I tried to open it and I noticed one coil "1R0 2127" gets hot when the charger is connected. Note: the charging light directly comes on when the battery is connected or the charger is connected.03-07-2025, 05:55 AM -
Hi everyone, I have a Nintendo 2DS XL that shows the orange charging light when plugged in, but nothing happens when I press the power button — no blue light, no screen, no sound.
Here's what I've observed:
All ribbon cables are properly connected
Battery is present and in good condition
No reaction even with screens disconnected
There's a visible burn mark / overheating sign on the metal shield, right above the CPU
I’m suspecting an issue with the CPU, PMIC, NAND, or a power... -
I have an Hp x360 15-u499nr laptop with a continuous white blinking power light. The laptop does turn on. The light flashes with just the battery and if I disconnect the battery and just use the power cord it still flashes and with both connected it still does. I have updated the bios and tried a hard reset with battery unplugged and power cord unplugged and holding down the power button for 60 seconds. I can't think of what else to try.

Hi everyone, I have a Samsung NP750QFG-KA3DE , MainBoard VESTA3-15 BA92-24515A
the battery is charged. pressing the power button the blue LED flashes 3 times and then stays blue. then the sequence repeats.
the fan does not start.
I noticed that I have no power on the processor and it does not heat up. could it depend on the bios?
any advice on what to check?
