Re: Samsung Syncmaster 245B - Screen freeze -> screen flash 4 diff colours

I have finally finished the job. While I am not happy with a lot of the solder joints I made (if you look at the picture), my monitor is, however, functioning right now, so that has to be a good sign! I am staying guarded because the monitor would work for a while before having issues, so we'll see. I also changed the resistors and scraped most of the yellow glue off. After more research, and an inability to find silicon that I was 100% comfortable using on my board, I opted to use heat shrink tubing...

I forgot to add, the three resistors on the bottom that everyone recommends to replace are all stuck together with this weird yellow gunk. I tried to gentle wobble the resistors, but this stuff has a death grip on them. What is it and how do I safely remove it so I can replace the resistors?...

Thanks for the heads up to double check my board.

Oddly, my board has 3x 47UF 50V instead of 2 of those and a 47UF 10V. I would have been really confused what to do with that 10V when it arrived :P.

I was looking at getting one of those capacitor kits sold on ebay. I messaged the seller, and these where the ones he said came in the kit:

1 - 10V 2200uF, Panasonic FM
2 - 35V 1000uF, Panasonic FR
2 - 10V 1000uF, Panasonic FM
1 - 35V 470uF, Panasonic FM
1 - 50V 100uF, Nichicon PWM
1 - 63V 68uF, Panasonic FC
2 - 50V 47uF, Nichicon PWM
1 - 10V 47uF, Panasonic FC
1 - 50V 22uF, Panasonic FM
1 - 50V 10uF, Panasonic FC
1 - 50V 1uF,...

Sadly, I don't have anyone that regularly solders electronics... My only option would be to learn myself, or just buy a board :P

Re: Samsung Syncmaster 245B - Screen freeze -> screen flash 4 diff colours

Wow, such quick replies, you guys are really impressive!

This is my first time with any electronics repair, and it is kind of intimidating. I'll have to do my research this week on how to replace caps on a board.

Thank you both RetiredCaps and PlainBill, you're both great!!

Sorry for the ridiculous delay in getting these images. Just started a new job and things have been hectic.

Anyway, I have some even closer shots of the boards done in sections should you require. Please let me know.

Thank you again for your attention and help! ...

Thank you for your kind reply!

I will do as you ask later in the week when I have time.

Hello,

My monitor has experienced a major malfunction. The screen will randomly freeze, and then get uncontrollably brighter and brighters. Sometimes I can use ctrl+alt+del to snap it out, but now it starts rotating the same four screens over and over again. It will switch from dark, to white, to blue and to red-gren-blue-white stripes.

I searched Google for some answers, and best I could find was this video on Youtube which demonstrates the exact issue I'm having:
