Re: Need schematic for Tryptico 6050a2945701-mb-a01(a1)
So on the microscope I found a bowl element /Attachment - DTGV 14.jpg/, but I can't identify it.
It is "DTGV 14", but I can't find what kind of element it is...
Can anyone identify this smd?...

Re: Need schematic for Tryptico 6050a2945701-mb-a01(a1)
With ot without schematic I'll try to explain what is the problem with my board.
In Pic1, with red dots I point where I have short to ground.
So I need help to solve this problem...
My assumption is that cpu is gone, but I want your opinion......

Need schematic for Tryptico 6050a2945701-mb-a01(a1)
I have short on the board and I need schematic.
The laptop is EliteBook 745 G5.
And if someone can find error codes for blinking lights, near to the adapter plug, pleace post them.

Asus X51RL REV:2.0 ; pn:08G2005XL20J - won't turn on!
Hellow to all
I have a problem with Asus X51RL.
It does not turn on.
I have the schematic but I can't understand why the second switch won't open!
On pq5700 pins 5,6,7,8 = 19.47V; pins 1,2,3 = 19.17V; pin 4 = 18.9V...

Re: Hunting camera repair - HC500M.
So I recheck my measurements, but the result is the same.
I remove IC TI TLV62130ARGT. I remove the processor and memory, but short is still there!!!
Any other suggestions!...

Re: Hunting camera repair - HC500M.
So no output voltage on pins 1,2,3. No short on output. I check all mlcc - no short.
From the datasheet that you provided, I see that pin 13 EN - must be High=enabled, but there is no signal on this pin./Attachment 1/. So my logic is that there is no Enable signal to start the IC. I try to follow the line, for this signal, and it goes to pin 7 on this MCU - STC15W401AS - 20pin /Attachment 2/. Datasheet /Attachment 3/.
On this MCU I measure - ground on pin 10 is OK, and there is 6V on pin 8. But nothing on pin 7.
I don't know...

Hunting camera repair - HC500M.
Hello, I came across a hunting camera HC500M with a number on the board - HC500M-3G-UC15-V2.6 20170808
The problem is that didn't turn on. Attachment 1 and 2 are the board.
First I want to ask if anyone has a schematic on this circuit board since I couldn't find it anywhere.
When turning on the camera, there is no power on the two phases that I see on the board. There is power on the battery. On the board, there is two line key for turning on the camera, on one of the lines there is power on the other one NO. I manage to trace NO power line - she goes to BIOS chip and then...

DA0Ti7MB6D0 - TOSHIBA CLICK MINI L9W-B - schematic place help
I need schematic for this tablet. It give me short on one of the phases...
I changed this voltage regulator around the phase.... but nothing.
The regulator is SND9039A1 - if anyone can find datasheet- thanks...
In the attachment there is picture on the board.......

Re: HP Compaq 6730B INVENTEC 6050A2219901-MB-A03 won't start!
I have one "good" news, it seems that the BIOS chip is corrupted.
I try to flash it with a new one 3 times, but it gives me an error in one sector...
So I'll purchase a new one and I try again.
I want to give little info, how I manage to run SIVAVA / [url]www.sivava.com[/url] / Programmer on LPT on Windows 7 64bit.
First of all try to find PC with LPT on the motherboard, because I lose 2 days trying run it with PCI-to-LPT board, and I couldn't.
To run it on 64bit Window...

Re: HP Compaq 6730B INVENTEC 6050A2219901-MB-A03 won't start!
So I try to find this R757 resistor, but I couldn't.
I measure pin3 on U27 there is 0.9V
I think there is HDD activity, because when I connect lights on the board, the light for HDD is blinking every ~2 seconds...
I change the memory with another one, but still the same...
I plug speakers - no beep codes.
I don't have an oscilloscope, but I decide to take off the BIOS and check it with programmer, and flash it with the new firmware...
I'll leave comments...

Re: HP Compaq 6730B INVENTEC 6050A2219901-MB-A03 won't start!
First of all, I want to answer about Q522 - resistant between S - D pins is 25 oms. Resistant on Q520 between S - D pins is 50 oms. So I decide to change Q522 with a new one... - but and with the new one, resistance is 25 oms...
If I turn on the board and live it to work, after turn it off - Q522 - resistant between S - D pins is 13 oms. Resistant on Q520 between S - D pins is 26 oms... Both are changed with new ones, and the result is the same.
H_PWRGD
I can't measure H_PWRGD, because I can't...
