bad Advueu LCD monitor, blown capacitor

[jboker]

i was sitting at my computer and could smell something burning... it was my monitor that is out of warranty. i opened it up and found a burned up capacitor and im trying to figure out where to get a replacement, everywhere i've looked doesnt have it. Does anyone have any ideas?

thanks in advance

Re: bad Advueu LCD monitor, blown capacitor

It's a ceramic capacitor rated for 3kV. The capacitance value is not fully readable, check the value on the other one (they should be the same).

yeah, it says 18J 3KV, so it's 18pf with a +/- 5% tolerence, correct?

i've been searching and havent found anything. most caps arent rated with that high a voltage.

i am by no means an electronics person, so excuse my ignorance, but which capacitor would do the job?

Re: bad Advueu LCD monitor, blown capacitor

you can use a 1 nanofarad at 3kv for replacment.

but you gotta look at the cause of the failure. arcing being a possibility? those ceramics just dont "fail" like that. unless there is a cause.

This is just the direct output to the CCFL series'd with the capacitor. I don't see how there can be a cause of failure other than a defective part. If you have any cheap CCFL kits that people tend to shove in their towers these days, you'll find the same caps inside the little inverter boxes. Nab one from there if you have one readily available.

Digi-key has them, their part number P9645-ND. It's a Panasonic KGE series, designed for the 'Ballast circuit of LCD backlighting inverter'. The only problem is you will have to buy 10 of them. With shipping your total cost will be under $6.00 IF you are in the US.

Burnt pretty bad. I wonder how the transformer and the lamp are doing.

Ohhh-Kayyy.

Well, when you check back because replacing those caps didn't help please feel free to withhold other pertinent information. Parts suppliers need all the orders they can get.

well whn i did a search for the cause of the problem, thts all i cud find for a fpd1730, the 4 amp fuse tht is normally the problem wth tht model is gd. and i have a fdp1530 tht does the same thng. so im open for other suggestions, im jst starting whth wht ive gt so far. i dnt thnk they will gt rich wth my little ol 5 buck order
