Re: I-Inc IF281D Display Problem

For the record I am not counciling anyone to "Worry about the Load Life rating". I am however pointing out that a capacitor with a longer endurance rating should last longer under identical conditions

Endurance rating is by MTBF(mean time between failure) which means when 50% of the sample group no longer performs to specification under test conditions. You may claim that the ratings of one make are fraudulent(CapXon?) or another manufacturer(Rubycon?) under-rates their caps but you have not stated this, only hinted that...

Re: I-Inc IF281D Display Problem

The rating is in fact a lifespan at 105C. It is designated as both "Load life" and "Shelf life" in the spec sheet, but don't take my word for it

If the CapXcon capacitors in my monitor were operating outside or on the edge of their rating then they clearly weren't suitable for the task to which they were purposed. Regardless the caps failed as evidenced by my effective repair by replacement. If you would like I'll bag up the old caps and mail them off to you so you can evaluate them with your ESR meter to validate...

Re: I-Inc IF281D Display Problem

Temperature definately influences capacitor endurance. With 4 CF tubes packed into about half a cubic foot things get pretty hot! I've installed a quiet fan to circulate/induct air through the chassis, hopefully this extends the life of my replacements.

The data sheet from CapXon indicates the same number of hours for shelf life as operating life. When I compare these to other makes/lines with up to 20k hours of service life they just don't seem like worthwhile components for anything but a disposable camera.

Re: I-Inc IF281D Display Problem

I have an IF281D that was exhibiting similar symptoms. Periodic black outs with increasing frequency preceded by shimmering text at the top of the screen and an occasional ghost image displaced horizontally. For a time I averted the black screen problem by removing the shroud and directing a high powered fan at the electronics on the back.

Based on the visual artifacts I discounted the possibility of inverter/back light failure and recapped the input logic board. So far the repair seems to be successful.

The CapXcon caps...

Re: New Members - please post your introductions here

Hello badcappers. I'd like to introduce myself.

You can call me Nightstar. I'm an occasionally employed cheapskate with basic soldering skills in possesion of a multimeter. My chief intersests are keeping my stuff working so that I can add more stuff to my pile as opposed to replacing my stuff every three years or so. I aspire to one day get ahead of the degradation curve and actually build something instead of repairng something else.

I've been lurking on your boards for years, but only when I have...
