Hi Badcaps users,
I recently was given a broken Samsung 215TW that I'm about 90% sure has bad caps on the power board. When the monitor powers up, the blue power light appears, but the picture only comes up after warming up for a few minutes. When it does appear, it's super dim. After a few more minutes, it will get brighter but flicker like crazy then the picture will completely cut out entirely.
I searched on google to see to if I could find any reason for the problem, and I stumbled upon this super helpful forum. I read the thread located here which explained a lot but I still have a few questions.
I took out the power board and placed it in a known working Samsung 215TW. The good monitor would power on, with the blue light, but no picture. It never had any picture appear after waiting a few minutes, not sure why, but it seems that board is the issue.
I unfortunately didn't have time to put the known working power board into the non-functioning monitor to see if it was just the board and nothing else. So for now I'm assuming it the power board and not logic board with all the input connections.
Anyway, taking a look at the 6 brown caps, it appears that all of them are bulging. So I plan to replace them with better caps, but I'm a completely new to replacing bad capacitors. I don't know which brands would be good to replace it with. I know Digikey has a lot of selection for cheap capacitors, but it's a bit overwhelming.
I know that I need the following caps but other that info, I'm not sure what what type, or what brand to purchase.
1x 47uF50V
2x 820uF25V
3x 330uF25V
1x 180uf450V?
Also, I'm not sure I need to replace the larger. Can anyone give any suggestions?
Thank you,
JWatson
