Re: Lg 32lc7d
You are kidding, right? This old TV does not use LED for backlights, it uses CCFL.

Hello everyone, I have a constantly blinking Inexive LED TV.
Display is: VES390UNVA-2D-N01
Mainboard: 17MB97

Hello. I came across with the power supply constantly resetting on IPAD A1673.
(I connect it to USB power)
PMU U8100 is rising all voltages except PP3V3_S2 . Consequently, the SYS_ALIVE is also absent.
I have two identical boards with the same symptoms, and I think this is a common problem.
I also have a working board. I've taken all the measurements to compare and haven't seen any abnormalities. There are no signs of a short circuit or water damage.

Looking at the main board, I do not see any blown capacitors.
I uploaded a pic of the main board, and a short 22 second clip which shows the issue.... -
Hi,
I’ve got a stubborn patient here. The laptop powers on and works, all components like the screen, keyboard, touchpad, etc. are functional. The issue is that it heats up very quickly under load (within a few minutes up to 95°C) and then shuts down shortly after. Subsequent attempts to turn it back on right after a “hot shutdown” result in it shutting off within a few seconds. Interestingly, if I enter the BIOS, it can stay there for 2 days without shutting down (most likely due to low CPU load and low temperatures).
The cooling system has been cleaned, thermal...09-03-2025, 09:32 AM
