Re: biostar u8638 freeze on boot screen 6d error code
check for any carbon accumulation on the SIO, Clock, CPU power IC etc. Re-solder if necessary.

Hi Folks
I have an MSI PRO Z690-A DDR4 (MS-7525) which underwent LGA1700 replacement and had a missing resistor in the VRM section. The missing resistor RV170 (49,9Ω) has been resoldered, and I have also replaced a demaged LGA1700 socket.

Also restarting the board from Windows ends up with stuck boot process, but restarting the board again (long push Power Button or switching off and on PSU). Under Windows etherything works... -
not sure how it happened but after replacing the screen on a2251 macbook it:

Hello everyone,
I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the... -
Hi,
I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...
