LG 42LB1DR DVR TV Powers Up For Sec Two Then Shuts Off

08-24-2017, 07:35 AM

I have an LG TV with built-in DVR..

It powers up fine, but after a few seconds, it shuts off..

I have tried it without the DVR HD attached, no luck..

I have replaced the Power PCB and both Main Boards with no luck..

Thinking it might be the inverter boards, I tried it without the inverters hooked to the Power PCB...

Same thing. Powers up for a sec or two and then shuts down..

I am at a loss on how to proceed..

ASUS B5402CEA – Laptop powers on for a few seconds then shuts down

by riki_22

Hi everyone,

I’m working on an ASUS B5402CEA notebook.

B5402CEA_MB_R2.2
HA4YT LA-L861P
REV:1B

The board powers on, fan spins for a few seconds, then it shuts down by itself.
I suspect the BIOS might be corrupted.

Could someone please check and clean (repair) the attached BIOS dump?
I’ve also attached a few photos of the motherboard for reference.

Thanks in advance for your help!

PlayStation 3 Super Slim (CECH-4004A) powers on for a brief moment and immediately shuts down. But works without cover..

by Tony182

Hello everyone, I received a PS3 console with the issue described in the title. I gradually measured the console (both the PSU and the motherboard) but couldn’t find anything—everything seems fine.
I planned to remove the casing and test whether the voltages appear on the coils, but after rewiring and turning the console on without the casing, the system actually booted, which blew my mind (it’s been seven days that I’ve been dealing with this). The processor started heating up, so I quickly turned the console off and tried reinstalling the heatsinks and turning it on again....

Help with Dell Latitude E5470 that shuts down when moved at all. Powers up, but no charge, power jack has brown burn marks

by lowpost99@gmail.com

I have a Dell E5470 that powers up and boots windows no problem. Using a non-standard universal type charger, it shuts down immediately if moved, (power short in that charger or AC power jack) because the battery has no charge and isn't charging orange/white lights blinking on the front. When first powered up, BIOS power alarm stated that it could not detect the voltage setting and I had to dis-able the message to get past this. It got into Windows fine, as long as not moved, so I dis-assembled it looking for a cold solder joint on the power jack that I thought might be lifting off the MB, but...

Dell laptop powers up with kb backlight about 10 seconds, then shuts off

by survivalbloke

I've got a Dell Latitude 5580 which came in for no power. It's not exactly a no power issue though. The battery was puffy so I replaced that, but the symptom is that when the power button is depressed, the keyboard backlights will come on for about 10 seconds then go back off. Before depressing power button, I am drawing 112ma and oddly, there is no change in current draw once the button is pressed and the keyboard backlights illuminate.

Any ideas?
