Default tv repairable or not

You claim to be of "reasonable electrical aptitude" then you should be able
to identify the vertical IC on its own heatsink. Inspect the PCB for any
cold/bad solder joints and resolder appropriatley. First performing a
visual inspection of the vertical area, If you have an ESR meter (a must if
you are servicing) you should check the vertical area for leakly, high ESR
electrolytics,otherwise you will have to resort to the more costly, time
consuming method of trial and error

Good luck

I dunno... My grandmother had an oldish (1988) Philco 27" console set

that
had collapsed and she kept using the set for many months just to

listen
to
the audio! She would let it sit and run with this bright as can be

white
line across the screen and didn't mind it at all.

I finally happened to be over at her house one day while the set was

running
and I noticed what was going on. By the time I saw the set, the line

was
no
where near as bright as they are when they first collapse. It had

*plenty*
of burn! Of all things, this was such a simple problem, too... This

set
had a small switch for Service Mode that collapsed the verticle sweep

and
it
had shorted! Cleaning the switch returned proper operation of the set
except for a black horizontal line across the middle of the CRT...

It's a very easy repair job, however if you run it for long with

the

white line you'll burn a line into the tube and it's a writeoff.

Well, I assume it's pretty boring watching a white line so maybe

common
sense will prevail.
