TV Repair or Replace
 

I have a 35" Toshiba TV. It's about 10 years old. I just turned it on and
all I see is a horizontal white line across the center of the tube.

Question: Repair or replace it?

Thanks

Get a bid on repairs to the vertical deflection circuit. May be just a few
components, if the picture was on before the failure it may be cost
effective to have it repaired.

REPAIR it.
bad vert defl chip? bad flyback derived B+? faulty solder
connections? High ESR caps? , etc, etc, etc.
As long as the picture was good right before the failure it is
definately worth repairing.
It is probably not too expensive at most shops..... it would be best
if you TOOK it to a service shop for, at the very least, a repair cost
estimate so you can make an intelligent repair decision with facts
instead of internet wild guesses. A real, in person tech will have to
look at it and open'er up and do some testing to determine the exact
failure and susequent estimated repair price.... can't be done with any
certainty otherwise.

If you have some electronics skills and am handy with a solder try to
locate if there is a cold solder problem. One of the dignostic
indicators was that the problem could be temporaliy fixed by slapping
the sides of the TV = loose connection somewhere.

The gist of my fix was to open up the back cover. Switch on the TV.
Use a long wood dowel to move around or tug on the wire harnesses.
One of the tugs on the CRT PCB harness reproduced my TV's problem.
This was horizontal white spaces and spread out scan lines on top of
the screen. Traced that to a practically invisible crack on the
solder pads for the pin connector on the PCB. Reflowed the solder.
The image now is even sharper and better than before.

If it had a good picture before then get it repaired, that's a real
simple fault to fix provided you haven't run it long enough to burn a
line into the tube.

Yes simple repair for a shop . It should not cost more than 50 to 60$ if
so then you are getting gouged .

In one of my TVs that same problem was caused by a bad 180V
electrolytic capacitor in series with the vertical yoke, but in another
a transistor in the vertical output chip blew. The chip was $15, but
some local places wanted $50. Fox International, MCM Electronics, and
other sources listed in the www.repairfaq.org are usually cheapest.

Many libraries carry Sams Photofacts schematics, either on paper or
online, but it shouldn't be that hard to find the vertical output
section by tracing the wires from the yoke and looking up the part
numbers of the transistor or chip to find out their functions.
www.nteinc.com has information for a lot of those parts.

Be careful about letting the TV fall forward and making the CRT shatter
and explode.

I charge $64 if it requires resoldering the vertical IC and $84 + parts if
it reauires changing the output IC and/or any caps. I don't think I am
gouging anyone.

Those rates, of course, include routine adjustment of focus and white
balance, resoldering other components that might need it, leakage test, and
verifying the operation of the tuner, switching, and condition of the CRT
before fixing the set. If I had to charge less it would not be worth my
time.

Worth fixing for sure. If you take it in to the shop the labor should
be between $75 and $90 depending on exaclty how many parts need
replaced plus the parts, typically $25-40. Add the trip charge to this
repair guess amount if you want to do come out and do this. Most shops
will want to keep the total repair on a set this old even in this size
under $120 maximum for a complete repair and check out with that type
of problem if you take it in.

Odds are very high on a 10 year old Toshiba that a quality repair will
require checking the known electrolytic capacitors for potential future
failure in addition to the few capacitors in the vertical that are bad
that took out the vertical ic and fusible resistor.

You do want to make sure you call a reputable shop that has the
experience so they can actually fix the known potential failures that
could happen soon after this repair so you won't have to pay again.
Realize that even if you take the tv in, it is going to take two people
to move the tv around and then a well experienced tech should have not
more than about one hour in the set for the repair, then another couple
of hours of bench repair test time.

Ditto, you cannot even afford to break even with a good tech on the
payroll without recouping at least $85 for each hour they are working.
Every job that requires replacing a part basically takes an hour labor
from start to finish.
