@TheSlipknotist Sorry, I'm not sure what the problem is. I mainly work on vintage electronics. Maybe you could search the internet for your specific model number and find some help ?

i have a dual lcd monitors samsung 2233bw i have a nvidia card they both worked fines for about 8 months and now one doesn't work , the one that doesnt work is just black and the blue light at the bottom blinking all the time the other one work just fine what do you think is the problem the capacitors?

[bandersentv]

@7655walter Most likely. I've also had a cap blow out on a video card. It made a heck of a loud pop and the computer screen freaked out. I shut it down, replaced the blown cap and it's been fine for a couple years now :)

@7655walter This is the only video I have on repairing any computer stuff. The few times I've replaced capacitors, it was obvious which ones were bad because they were bulging and leaking.

Check out the Maxxarcade youtube channel. He has a bunch of videos on repairing computers and knows way more than me.

Not all caps will show signs of being bad, many simply dry up. The capxon caps are crap from the get go, so if anyone has them, REPLACE asap. Panasonic and many other brands are a big improvement over these. Get low ESR caps, make sure the uF are the same as some switching supplies will not like it one bit if you stray from the printed uF rating and never ignore the little electrolytic capacitors. Good job on the repair and glad you didn't get more Capxon caps, ugg!

@certified30 Thank you.

@moonwine if your monitor turn on for 2 to 5 sec and turns off, and you got no bulged caps, then you need to check you LCD inverters, they probabaly gone bad, interters are those blocks next to where the LCD backlight plugs are. when the inverters don't hold the charge from the power supply, the monitor goes black bacause no light gets to the screen.

nice video, i just wnated to add that when you replace caps always replace with higher Voltage than the bulged ones exemple if your bulged caps is are 10V 1000Uf replace it with a 15 or 25V and same Uf if you want to avoid having the same problem in the futur, i have repaired hundreds of monitors and never had the re-repair them again. the big cap does not need to be changer it looks ok. sometimes its is the inverter that is the problem, it is rare when the graphic card fails.

A good place to get capacitors is The Cap King.
