Subject: [TechAssist] Mitsubishi CS 3550S Blows H.O.T
Hi Gang,
This Mits is giving me a bad time. It came in with a Blown H.O.T (2SD2349),
and a hole in the Vertical Output IC (TA8427K). I replaced both of these
with OEM parts,..installed a new B+ fuse, soldered Horz. driver transformer,
and couldn't see any bad connections. I fired it up, and as soon as I heard
the static from the high voltage come up, it blew the H.O.T, and B+ fuse
almost instantly. I am thinking about removing and ringing the IFT, but,
just wanted to see if you guys have any other ideas first. I might change
the Reg IC (STRM6511), and try again, but, I only have ONE more H.O.T., in
stock. Don't want to blow it, if no need to.
Any help is appreciated,
LLW
