Greetings everyone.
Please I need help with the above monitor.

Below is the summary of what happened and what I have done:

The backlight driver IC is 0b3350cp.

I applied a 370k SMD resistor on the CMP pin which is pin 6, while the other...

Greetings everyone,

I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

At first everything was working smoothly, then I decided to change the connexion between the video board and the screen for a longer one. Still working fine

During another reassembly, I made a mistake, and...
