Short of having a proper flyback tester, are there any tests with a
multimeter that would strongly indicated a shorted flyback? I have 2 P810's
(viewsonic) that I'm pretty sure have blown their flybacks but wanted to
confirm before i strip them down for parts..

Thanks

I ring flyback,SMPS's xfmers,video heads,yokes and other x-fmrs using
the calibration output of my TEK465 and two 0.1Uf poly caps:

and it works great.

HR Diemen of Spain makes top quality flybacks,SMPS transformers and
test equipment which have ISO9001 & maybe ISO9002 certification,they
are now the OEM supplier for Sony who as we all know have poor
flybacks,the proof is on their website,CD ROM and paperback catalogs.
They also have free online specs for each of their products including
schematics.

They manufacture the world's best flyback transformers:

it as well.Here is an article that I contributed to NESDA:

if the flyback is a TLFA01365, its a high fail flyback. They retail for $65,
but good reliable replacements can be found elsewhere cheaper. Try searching
google for that part number.

Yep thats the beastie alright and I've read this sad news many times--just
wanted to confirm for myself I guess--I've also read that proprietary
viewsonic software is needed to calibrate the new flyback--if this is the
case its pretty much landfill fodder (as was viewsonic's intention i'm sure)
Can anyone confirm or deny this? if this is true than a new flyback
wouldn't help me much.

there is a tweak to adjust the HV up on the replacement TLFA01365 , if it
winds up being a little low. The TLFA01365 has G2 and focus controls right
on the flyback, and I have not heard anyone needing to tweak the G2 or focus
because of insufficient gain. There are a few SONY flybacks that you have to
tweak nearby components if you dont have their DAS, and theres no way
around it.

if you go he www.kazazz.com (search engine) , type in that part number ,
and go to result #14 (products IIB) you can purchase a replacement online
for $31.99 ea shipped in the USA. Also included are the tech notes with a
purchase on how to tweak the HV.
