You are going to have to open it up and check for bad caps - post pictures
please post good clear pictures of the whole chassis, and then pictures of each board, front and back and close up of connectors, (max resolution 2000x2000 and 2MB) using the manage attachments button, which is found by clicking "go advanced" under quick reply.

Re: Memphis 1000w amp
Are any speakers connected?
Likely a shorted amplifier stage, hence the amp going into protection mode.Muh-soggy-kneeComment

Hello all,
I'm stumped on this guy, so wanted to see if anyone has any further ideas:
Intro:
This is an Acer Nitro 5 AN515-55-55M1 with unknown prior history (bought "as-is" on eBay). It charges the battery and powers on from both AC adapter and battery, so I think this rules out main power issues.
Upon attempt to boot, it will "reboot" (meaning powers down and then powers on again) only once, and then stays stuck in a status of lights on / no post / no monitor. Powering on with fn+esc maxes out the fans on first boot attempt,... -
Hi it looks like everything works don't know where to test except the 390v in the 2 capacitor in the hot side of the power supply and the weird 180v in the diodes in the cold side that should be discharged it is writin on the circuit no more you can read what is written on the circuit quite srrange color mixiing yellow and white
anyhow i couldn't t read anything else
the backlight is on strong and the screen does not get dark or very dark but no pictures
the mainborad feels a bit hott on the black part i test it to 52 degree's against 34 to 40 on the rest of it

Powers on as normal shows an image then powers off after 10 seconds
I have to unplug it from the wall and replug to get it to turn back on but then shuts off
No blown caps
I searched for this model but nothing comes up...11-29-2024, 11:21 PM -
The 55" LG has been in the basement for a few months without being used. Turned it on yesterday, set came on as it should and showed a complete screen for about 5 seconds (was on a broadcast channel but no antenna was connected), then the screen went mostly dark with about 1/3 of the screen on the right lighting up with brighter lines in that lit part (sorry, no pictures of that). Power LED was cycling too, preventing the TV from fully powering up.
Pulled the back off, all boards looked OK. Pulled the LED connector, turned the set on to see if it would power up but I don't belive it... -
Hi,
I am new to this forum and have searched for some answers with problems similar to mine.
Philips TV powers on as normal for about a minute or less then click and no power at all not even standby light. If i disconnect from mains and reconnect it will power on again but for a shorter time. Once i leave it disconnected from main for a longer time it will power on for a longer period the next time.
It sounds like a power supply issue?
I have the board out and want to run some tests. Not sure what i should be doing but i put a 1k resistor across SB and +5v...
