Dear Badcaps forums, I love you.

My girlfriends monitor ceased working yesterday. it would power on for 2 seconds and proceed to shut off. I was furious, I had gone through a lot of trouble to aquire this monitor, I'm not made of money so I had to do alot of work for a friends relative to get it. I decided to google any possible causes, I came up with nothing. So I went and tried to open the monitor to fiddle about. It's a Medion 17" monitor. But Medion are an extremely vague company and it was impossible to find sufficient support on the device. So I continued googling and found a page showing how to open the monitor, which was a pain to figure out. After doing so I removed the LCD panel, and the power board. Now, I've had no electronics training in my life. I'm a 22year old with no further qualifications than the Irish Leaving Certificate. But when I saw some strange brown stuff bulging from the top of the capacitors on the board, I got worried and curious. So I typed in the name of the board; Mirage Electronics AD-1700 Rev:F 200-000-170DTL1 VERSION:A, along with "faulty capacitor". With this, your wonderful site appeared in Google with the following page: Mag LT916s Model 900p 19" LCD dropping like flies.

This page, helped me so much, you have NO idea. After reading this I went to Maplin Electronics in town, all they could provide me with was 3 x 470uf 50v capacitors which were almost too wide to fit. I went down the road to Petes Electronics and had a long discussion with an extremely nice guy who explained capacitors to me, though their stock wasn't wonderful either he still provided me with a vital 220uf 35v which was also slightly too big but I figured I'd manage. I picked up 2 x 100uf 63v because I figured I wouldn't risk those going, they're FAR bigger but I decided to try anyway.

So we trudged through the snow home as Ireland for some reason shuts down when a bit of snow falls, including buses. I began removing the bad caps and replacing them with the new ones, sure enough the size differences made this slightly difficult but it worked.

I returned everything to its place within the monitor, plugged it in, turned on the pc and flicked the monitor power switch.

It worked.

This is all thanks to this Forum that I even knew what to do.

Badcaps, you are wonderful!!

Well done. The next step is to remind your girlfriend how lucky she is to have you.

Welcome to the forums Marc. It's actually members like you that contribute to the forums so also thank yourself .
Nice job on the recap, too. However, you might want to replace the rest of the Xunda caps (except for the big 200v one) as they will probably fail later on as well (if not already). Also what caps did you use as replacements?

By the way, are you sure you've never had training in electronics? Because you did a pretty good job at troubleshooting and repairing that monitor .

Re: Dear Badcaps forums, I love you.

Hey Momaka, the gold ones are Hitano, that's the 1 x 220uf and 2 x 100uf's and the blue ones are Jamicon, the 470uf's. Oh and yes, I had to Google uf as I had no idea what it meant I've no idea if these are good or bad but they were the most expensive. I do intend on replacing the rest of the Xunda caps, it's just the 3 I got were literally the ONLY 105degree polarised 470uf's in either of the two stores, so I've put an order in for 3 with Pete's. I've had no training/courses, I'm considering going that way though. Thank you very much for your kindness folks, and thanks for this little pot of knowledge My next wee project is 2 motherboards I have that are not functioning. I wouldn't mind but one is an Intel DX58SO which cost €260 at the time :| Should be fun!

Not too bad then. Jamicon are usually a-okay capacitors in PC PSUs and I haven't really heard any complaints here about Hitano. Of course it's still better to substitute those with proper low-ESR caps as those Jamicon and Hitano caps might also fail since they are likely not of low enough ESR. For PSUs and LCDs, usually Panasonic FC and FM, Nichicon PW and HE, or United Chemicon KY, KZE, LXY, and LXZ would be good replacements. farnell.com and mouser.com might have them.
I think Samxon RS are also suitable and you can buy them from here (badcaps.net).
