Re: LCD TV won't turn on. LED keeps blinking
I got it from another forum im also on its a pity it does not give the values of the parts but its a start i guess but being honest i do think your better of getting a replacement board on this occasion but i guess it depends on availability in your country etc, now we have this diagram maybe someone can advise on the low vcc voltage too that ic.Comment
for the diagram i searched in google but i didn't found

Hi everyone,
I've got this LG TV here that wouldn't turn on and be stuck in a standby loop (blinking red once every other second).
Did test the following:
* LED's seem fine as they all light up using LED Tester
* Power Supply supplied around 111V for each LED Strips (2x edge lid strips)
* PWR_ON would be at around 3V but dropping every other second (just like the standby light)
* DRV_ON is doing the same
* power supply has a green LED onboard, but that doesn't seem to do anything (stays off the whole time).
* there is a tiny clicking... -
Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok. So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited... -
Hi there,
I have this ASUS X453MA Laptop that's not turning on. When I plug in the charger, the green light just keeps on blinking and pressing the power button does nothing.
I have checked the charger and it is giving 19+ V
I have disconnected the battery and pressed power button for 30 seconds.
I tried another RAM stick.
Tried disconnecting the keyboard and touchpad.
Tried disconnecting the HDD and the wifi adapter.
The problem persists.
Hope you could help me out on this one. Thank you.12-14-2024, 06:40 AM -
Hello
I was looking for a schematic or board view but unfortunately I didn't find anything.
By connecting the drain and source of pq58, the device turns on and works perfectly, but the battery doesn't charge, and I don't know the path of the circuit to the MOSFET.
Is the problem with the adapter? Or is there a problem with the MOSFET activation circuit?
Please guide me.
Thank you. -
To all the members here...
Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.
So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But...
