PS5 EDM-033 blue led 1 seconds power off
Hi, I have a ps5 EDM-033 that lights up blue for 1 seconds and then turns off
the start sequence is correct, it reaches 320ma and then drops to 10ma
checking the card I didn't find any shorts
Reading the codes via huart gives me the following errors:

Acer Aspire A515-56 Main FH5AT LA-K093P no power
Hi everyone, I was looking for some advice on an Acer Aspire A515-56 with a FH5AT LA-K093P motherboard.
the PC does not turn on, the battery is completely dead.
checking the board I do not detect shorts.
the 19v of the charger stops at the first mosfet PQB3
on PUB1 BQ24781 pin 28 I have 19v.
connecting with a bench power supply I have no absorption.
nothing that heats up with a thermal camera.
any advice on what to check?
thanks in advance -
PS5 EDM-033 UART 80810001 Beep 1 second Ligth
Hi everyone, I have a ps5 EDM-033 that beeps, blue light for 1 second and turns off.
reading the error codes via uart gives the following code:
80810001 General power failure (periphery, GDDR6, APU, data line shorted)
checking the card I didn't find any shorts, Boot sequence is quite right 325 mA dropping to 9 mA.
Using the thermal camera I can see the SSD controller and South bridge getting warm.
if I press the power button the RAM also heats up, the processor doesn't seem to. in fact if I go to measure I don't have +1v CORE output.... -
I tried to redo all the soldering but nothing. In the end I solved it by changing IC SLC1013M and SLC2013M. Thanks to everyone for the helpLeave a comment:

thank you very much the new bios works well.
At startup I had to enter the service tag and the exact model.
but now when windows starts it asks me for bitlocker recovery key which would be the reason why I tried to repair this PC.
do you have any advice? maybe there is some option to activate in the bios.
I read that someone opted for a bios downgrade, do you think this will solve it?
thanks...Leave a comment:

Acer Nitro 5 FH52M LA-J891P no display
Hi everyone,
Acer Nitro motherboard FH52M LA-J891P Rev.. 1B
The laptop arrived with a short circuit on the main power supply line +19v
After measurements and a short circuit test it was discovered that PQZ2 (AON6962) and PQB11 was damaged. After removing it from the board, the short circuit on line disappeared.
once the components have been replaced the mainboard now starts but does not give any image on the screen.
the fans spin, the keyboard lights up but no image. if I put a USB stick with LED it doesn't flash. If I remove and insert the power supply... -

lenovo V145-15AST LA-G241P shorts out the battery charger
hi, I'm writing about a strange problem on levono V145-15AST with LA-G241P motherboard.
The PC turns on and works fine. the battery charges for 15-20 minutes and then the battery charger goes into protection mode. Already tried another battery charger.
the charging LED flashes 3 red times cyclically when it drops below 20% and is being charged. when it reaches above 20% the charge LED turns solid white but turns off for an instant every 4-5 seconds.
Charging chip is intersil 88739A
I noticed that the components circled in the photo heat up quite a bit when charging.... -
SHARP LC-40LE814E does not turn on 2 flashes
hi, I have a sharp tv model LC-40LE814E with DPS-126CP-1 A power supply.
the tv initially turned on, displayed the image for 10 seconds and then turned off. so in a loop until the power was cut off.
reading the classic optocoupler problem I changed the mounted cosmos with SHARP PC817 recovered from other boards.
now the TV turns on for 1-2 seconds and turns off giving 2 flashes in the front LED.
to avoid banging too much I preferred to take an identical tested and working card (or so the supplier says)
