LG 46LD550 turns itself off after a few minutes then will turn on and off 3 times

06-09-2015, 01:38 PM

I have an LG 46LD550 LED TV. It stays on for a few minutes then shuts itself off. After this if you try to start it back up it will flash on and off 3 times then shut off. A visual inspection shows no blown caps anywhere. I assumed it was the power supply so I changed the Power Supply/Backlight Inverter, this however is not the issue.

So I am at a loss, before I change out the main board I thought I would see if anyone else has had this issue, and if so if they were able to figure it out.

I am a rank amateur at TV repair so if you need readings I will try to figure it out but I am more of a follow directions really well kind of guy, rather than a troubleshooting kind of guy.

Thanks in advance for any help

Asus g750jx Bios turns off after 30 minutes

by Newmultifail

I have a problem with the asus g750jx, it shuts down exactly every 30 minutes. There is no overheating and the like, it works perfectly for half an hour. it turns off both in bios and in windows. My guess is that the bios is the problem, would anyone like to take a look and try to fix this bios so I can flash it again?
I should mention that the bios update did not help.

Philips 47PFL4606H/12 turns off after 10 minutes

by ressof

Hi

I have a Philips LCD 47PFL4606H/12 that turns off after around 10 minutes and then i cant turn i back on again without removing the power cord and attach it again. Then it turns itself off again after some minutes. When this happens the red led that usually indicates standby mode is off.

Can it be the same problem as in this thread?

asus x510u accelerating fan and after a few minutes it turns off even in bios.
i've tested only motherboard without battery, keyboard, replaced fan, disabled discrete graphics, replaced memories and still shutting down. I am using last bios.

MacBook Pro 14" M1 Pro Turns on functions then turns off when I plug in USB C cable

by Stephen

MacBook Pro 14" M1 Pro Turns on functions then turns off when I plug in USB C cable to reset the computer. I disconnect the battery fully and then reconnect it and it won't turn back on. After letting it sit for a day I plug the battery back up, and the MagSafe 3 cable and it powers on and stays ons, once I plug in a USB C cable into the port closes to the MagSafe port it turns off and the Amber light turns off and won't turn on. No water damage, nothing, I want to do a DFU restore to wipe the computer since the customer stated they did an update and ever since it just decided to not work...
