Re: Polaroid TLA-04641c no stand by power
What is your line voltage? 152 volts is rather low for the voltage across the large cap; that implies a line voltage of about 110VAC.
There are three ICs on the back side of the board; two toward the top, one near the bottom. What are the part number of those ICs.

Re: Polaroid TLA-04641c no stand by power
This looks like the right chip.
http://pdf1.alldatasheet.com/datashe...P1653ADR2.html
From the datasheet, it looks like pin 8 is your VCC and startup threshold is min = 12.25, typical = 13.25, and max = 14.5 V DC.--- begin sig file ---

The service manual is at
but the schematic diagram is all fuzzy (page 33) that I can't make out any detail (plus it is sideways).--- begin sig file ---

Hi all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

Hi all,
TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!

I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -

Hello, I have an asus Z97-A motherboard and it doesn't start which was working properly before, the problem isn't related by ram, ram slots or psu (I changed all and nothing work), the exact problem is when you switch it on , it starts and after 1 seconds (no boot or display picture) it's off and then on cycle continuously until you power it off from psu also it's responding to the power switch for turning it off if you keep pressing it 3 or 4 seconds (power button pin has 3.3v) , also when you start it with eatx 12v socket connected this is happening (power cycle also all voltages are resetting...
