I had bought this Westinghouse monitor about 4 years ago. It was working fine. Then one day it started acting funny, would display a rainbow of red, blue and green, maybe some other colors, the display would turn white sometimes to. And the menu screen and any letters would be distorted. As you can see in the attached video. At one point I couldn't even get it to display any video at all, even tried every different video port, used different cables, you name it. It was sitting around for a long time thinking it was garabage, then a few days ago I plugged it in to see if I could get it to work before buying a new one, and it actaully displayed some video but its missing some colors, so the color is really washed out, and the letters are distored. I did do a factory reset and that didn't do a thing. Attached are some photos of the inside of the monitor, I don't know if the caps are bad... anyone have any ideas??? Here is the link to the video of my monitor doing the funny thing. It seem like if I banged on it a few times it would start working better. lol I know that isn't good but may help find the problem... http://www.youtube.com/watch?v=UbPQTTq2Sn8

Re: Bad caps or somthing else??? Please help!!
Yes, the capacitors are going bad. Everything that's swollen at either end is turning bad but since most are in places where there's lots of heat, you should replace all...
You'll have to replace them with quality capacitors - Nichicon HM, HN series, Panasonic FM, FR series...
You have to look at the values listed on them ... the uF value you have to keep the same, the voltage can be higher but pay attention to the dimensions so that new ones will fit in the space.
If you say where you live and a list of the values listed on the capacitors, we may give you some suggestions.
picture shows what you need to change - the yellow ones look fine but considering the location you should replace them. (picture is washed out because program used to draw on it crashed when saving so I was too lazy to do it again so I print-screened the screen)
ps. shoot a picture of the green board and post it here, that may have issues as well.Last edited by mariushm; 10-10-2011, 12:06 PM.

by SluggerBI have an old Tivo. The Power Supplies are known to have caps that fail. Here are the caps that come with the original power supply:
I could not find replacement caps with the exact same specs. I followed an online guide and recapped the power supply with caps with these specs
The power supply now works, however the HDMI video is giving me eye strain. I don't know how a capacitor on a Power supply could impact an HDMI video signal, but it does, the Tivo interface has a flicker now and the color/brightness is off. So I want to get some new caps...-

by momakaI know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

by eryjusHello,
First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.
I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.
I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

by Paxman_SwedeHello!
I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.
The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.
I have studied the board and...-
