Only getting a 6-inch high strip of picture on TV

[Greg Bailey]

Hi, we have a 27-inch Sanyo TV that's a year-and-a-half old. Not HDTV or LCD
or plasma or anything, just a plain old tube TV, it's our third straight
Sanyo TV, we've had good luck with 'em in the past and the price was right.
We left the house for a while today and left the TV on ... we normally do
that for security reasons so that folks coming around will hear a TV and
think someone is at home. It was working fine when we left. When we came
home, it was not working fine. I would say we're getting probably a six-inch
strip of picture, that's measured vertically, horizontally it stretches all
the way across the screen, a bit closer to the top of the screen than the
bottom. What we are seeing is probably the top six inches of what would be
the normal picture, a bit distorted but still recognizable as such.

Does anyone here have a clue what might be going on with this, and how big a
fix it would be? I know this is the perfect time to upgrade to a more modern
TV, but with Christmas around the corner that would be an "ouch," plus we
are limited at least for the time being as to what size of TV we can
accomodate in our living room, and aren't really inclined to go to the
trouble of changing that at the moment. We have an old fashioned
entertainment center, where the TV sits inside the cabinet, unlike the newer
ones where you sit the TV with its pedestal on the top, and this Sanyo, at
about 26.5 inches wide, is absolutely the widest unit we can get into that
space, and we're not interested in downsizing to a 19-inch widescreen that
would be about like a computer monitor. There is a similar Sanyo 27-inch TV
available now, only it's 30.5 inches wide and it just ain't gonna work. At
the same time, however, if it's going to be a $100 or $200 fix for this TV,
then you have to consider whether it's worth doing that, since the unit
itself didn't cost all that much.

Thanks in advance for any help.

Sounds like the set may be running fairly hot if it fits in the space
that closely.

As to the problem, it sure seems like one of the electrolytic
capacitors associated with the vertical deflection circuit has gone
bad. You don't say if you are trying to fix it yourself, what your
background is, and perhaps most importantly, the model number of the
set. Since certain sets have patterns of failures, having a model
number, not just a 27in. Sanyo might get more responses here.

Gotcha ... this info is from the back of the set:

Model DS27425
Chassis 27425-07
Family/Group VB8D

No, I'm not trying to fix it myself, have no experience whatsoever in such
things and don't plan to start experimenting now. Basically, what I was
wanting to find out was how big a fix, on top of a bench charge, this is
likely to be. My first thought is to repair the TV if at all possible,
because we've been pleased with it and it suits our needs (we're not
chomping at the bit to go HD; quite frankly it gives me a headache).
However, if we're looking at $100-$150-$200 to fix an out-of-warranty TV
that cost only $249 new at Wal-Mart, then I would have to think strongly
about putting that much money into a new one rather than repairing this one.

I never have thought about the TV running hot in that space, maybe I should
and will keep it in mind in the future.

Well any time you take something to a repair shop you're probably looking at
$100+, but this should definitely be less than $200. I do this stuff as a
hobby, I usually charge about 50 bucks to fix something like this for
strangers, if you decide to upgrade, try posting the old set on craigslist,
anyone who's reasonably handy with a soldering iron has a good shot at
fixing it.

The set is 1.5 years old. I know caps can go bad from defects or design
problems in a short period of time but I wouldn't start there. Besides I
don't think the OP wants to do the work, he just came here for an estimate
