will not turn on at all. the power led is on but that's no change.

Re: Jvc jlc32bc3000
You say it stopped turning on reliably -- does this mean it would turn on once in a while, but not always? Did it get slowly worse over time?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Jvc jlc32bc3000
well I may have killed it good now. I was testing voltage at the regulators and may have shorted out something. now the front LED IS OFF and when I plug in the power the speakers pop. also the F3A fuse is blown.

Re: Jvc jlc32bc3000
You may be lucky; check both ends of the F3A fuse to ground, and if they're greater than about 10 ohms, replace the fuse. If your probe just slipped, it likely only blew the fuse. (You can solder a new fuse across it, or temporarily use a car fuse with wires soldered to it.)Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

I replaced the PSU with one from Shop Jimmy. still no progress. main board issue?Comment

Re: Jvc jlc32bc3000
The PSU was probably fine (it is nearly impossible to break a TV PSU by slipping the probe -- the power supplies are short circuit protected); you should test the old one.

Re: Jvc jlc32bc3000
I know this is an old thread, but I was wondering what became of this. Did you ever fix the main board issue? Did you replace the main board? Did you ever get this set working again, or is it headed for the trash?
I picked up one of these sets with the same issues all the way down to the last step. I found I could turn mine off and back on with the power button but if I allowed it to put itself to sleep then it would not come back. In which case I have to let it sit for an hour before it will come back on.
Please tell me you found a solution. I would really like to know if you replaced the mainboard in this. Thanks.Comment

Re: Jvc jlc32bc3000
Bumping this up
I just got one of these JVC/Vizio made panels. I have 5v but no 12v. Was this determined to be a mainboard issue?
I see there are EEPROM available and one of the causes could be tv will no power on. Mine sits with the red LED on and no change with remote or hitting the power button.Comment

Check PS ON signal from main board. If low/missing, indicates it is a main board issue.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.
Windows also shows ''Plugged in'' when charger is not connected.
This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.

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 -
A few months out of warranty and it's dead as a fart. XPS 8950 with a 12th Gen I5, 32gb DDR5 RAM and a GTX1650 GPU.....
Symptoms it's giving are really making a coin toss between bad motherboard and bad PSU....I'm leaning toward motherboard, but there are some strange irregularities with this piece of shit system.
Basic test:
Upon connecting power cord, system powers on by itself (no button push) for a second then powers down...and then powers back on again, I hear a relay trip inside the PSU, and then powers down again and that's it. It won't do anything else.... -
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...
