Hi all, I've spent the past week digging through the forums and guides to try correct my foolish mistake of changing hidden settings while tinkering around, and to be honest my heads overloaded so I'm hoping you'll be able to help.
I used a tool called 'Smokeless-UMAF' to access usually hidden settings in the bios. I tweaked one or two 'safe' things but made the mistake of tweaking a lot of settings under 'USB/Thunderbolt Configurations' when I didn't know what they did. For... -
In the above mentioned monitor, I removed the plug a few times and this resulted no power.
I opened it, soldered the dc jack and worked again.
But since then colors have changed, too bright (or something like this) and lines, eg letter, are not very crisp as they used to be, they are vague, like faded out.
I checked voltages on the main board, they look ok (according to the service manual. It' attached at the bottom):
IC600 (D9329)
pin 1 (BST) 9.6V
pin 2 (VIN) 13.5V
pin 3 (SW(Switching output)) 4.8V
pin 7 (EN)
pin 8 (SS) 2.6V

Hi guys; i have installed win 10 Home Edition from a DVD iso and it changed to Win pro ,how i change it back to Home edition without reinstall again ?Thanks -
Hi there,
I got 2 Dell laptops with a locked bios (dell management protection).
When I sent the dumps to this forum I got unlocked .bin files.
The issue I am getting the voltage on the bios chip pins has changed once I soldered the chip back (with the unlocked even original bios file) and doesn't turn on anymore.
Before I started to re-program the chip the voltage on the pins were 3.3V almost on each pin. Once I soldered the chip, voltage changed to 1.9V or 1.3V on few pins. No 3.3V anymore.
I appreciate any help to get me this... -
changed out the cheap HEC caps on my tv power board to a mix of nichicon chemicon and panasonic caps below.
now there's louder buzzing noise from the yellow thing in the upper left corner. (anyone know what that yellow thing does? is that the transformer?)
and the screen flickers in brightness. It's a light flicker, but noticeable.
the buzzing ebbs and flows, like cicadas buzzing.
in similar fashion, the brightness flickering ebbs and flows. the flicker might stop for a minute or two.
these are all low esr caps, and I'm wondering if that might...
