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 -
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 there,
I've got a 39" LG 39LN540V that's just spontaneously stopped working! The symptoms are - when I plug it in, the red light will flash on twice, then go out, there's no visible picture, and I couldn't see anything using a torch on the panel either. If I press the power button (either remote or on TV), the red light comes on continuously. If I press power again, the red light flashes twice.
The TV is using a power board EAX64905301. I've attached a diagram of the power output, I've tested the voltages with a multimeter and I'm getting the following:

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 everyone
Please help me with this laptop
HP Omen 15-dc0003la , MB DAG3DBMB8D0 REV. D
It doesn't turn on, when I connect the charger with battery orange light appears on power jack and without battery white light appear, it is fine I think
But if I press power button, power led flashes white once, only that, not consumes anything power, not start, nothing more.
Bios was programmed with a working version, no changes.
Voltages
+3vS5 = 3v when I connect charger, next goes to 0 (I think is fine)...
