Re: technika 42 lcd 910 power probs
these mosfets are probably my fault they have gone faulty , i accidently shorted one of the big caps when taking 24v reading on the invertor board , so i suppose the rapid discharge from the cap damaged them , hence me fault on the T.v changing ..oops

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,... -
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 -
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... -
I am looking at an A2337 and found this for the order of power rails and what they do. Can this be confirmed before I dive into hunting down power rails that do not exist or are not neccisary?
- PPBUS_G3H (12.6V-12.8V)
- This is the main power rail that supplies power to the entire system. Check this rail first, as it must be present for other power rails to work.
- PP3V42_G3H (3.42V)
- This power rail is derived from PPBUS_G3H and is used to power the SMC (System Management Controller) and other essential circuits. It should be present if PPBUS_G3H is working correctly.
- PPVRTC_G3H (3.3V)
- This
- PPBUS_G3H (12.6V-12.8V)
