This DTV307 60" unit is hell to transport and is located nearly 30
minutes drive from our shop out in country and is a big-time dog now.
Original compliant was botchy picture traced to a spotty CRT, changed
that. Unfortunely had to change all other two CRTs to stop the
picture cutting out and ability to adjust TV to specs because TV
already had long hours on it that CRTs had aged quite much so had to
change all just to get it adjusted at all and hoped to stop that
shutting down problem. The HV divider already replaced when we
replaced CRTs.

Shutting down or cutting out is either picture instantly winks out,
sometimes had to power cycle tv by pressing button, in extreme case
had to pull plug. No strange noises or fizzing smell.

But customer still complains TV is doing same shutdowns when customer
reset the picture settings to defaults, which setting that stops that
problem is unknown because customer have not called back with reply to
our questions.

There is no bulletin on this particular problem. Any thing to look
at, and this will be very diffcult to transport TV back to our already
crowded shop. Sigh. Really NEED the tips very badly.

Well?

Soon within this week or next, we must go out and look at it.
Transportation is a big PAIN and we had visited that unit several
times in past and had to haul twice so...

HELP?

Pay attention to lousy solder connections every where on the main chassis
assembly, including the stand up daughter board and the inter-connect
between it and the processor board that connects at the rear apron. Agreed,
these sets are an absolute Bow Wow to work on and fix. Thank the electronic
gods that Thomson dumped them and their near cousins.
Hopefully you have their diagnostic procedures and training materials. If
not E_Mail me and I'll see if there is an archive that can be made
available for you.
