Good Day All,

I am still trying to get these parts from a local shop that may be
able to get Sony components. However, either the shop is reluctant to
order me these parts (for fear of losing bigger piece of the pie when
they can fix the problem for me at 10X or 15X the cost), or their
computer is really down. Then, I hope someone in this NG would help?

The problem is relatively common for 93, 94 Sony TV, mine is of
chassis AA1, of "sudden death". A cold solder joint or more at one of
the push-pull transformer output going to the (usually) horizontal
transistor outputs (Q601, Q601) eventually caused them to fail
(shorted).

The transistor generic P/N are obvious, but I need to also replace
those varistors and fusible link(s) and would need industry parts that
cross Sony's varistors and fusible links.

Q601 (2SC4834) 8-729-019-51
Q602 (2SC4834) 8-729-019-51
VDR601 Varistor 1-807-288-11
VDR602 Varistor 1-810-053-11
VDR603 Varistor 1-810-053-11
R607 Fusible 0.1 ohm 1-202-933-61
R644 Fusible 6.8 ohm 1-212-853-61

Any helps is appreciated.
Thanks!
Dave

Go here and purchase Sony originals...

There are enough incorrect and inconsistent statements in your post to
indicate that you may be making more trouble for your self and are about to
waste money on parts that you may blow if you are not more careful.

First, the two transistors listed are not horizontal outputs at all.
Second, if cold solder joints that are common on these sets caused the
problem, the HOT would be shorted.
Third, if there is anything other than the HOT, Q601,2 and R607 damaged, the
source of the problem was NOT the bad connections at the HDT and you need to
be more thorough about testing the PS.
Fourth, it is a common misconception that original Sony parts are necessary
to replace Q601,2. The VDRs need to be Sony originals. It is also a
misconception that all three VDRs always need to be changed. Change them if
they are bad. If they are, you can bet there is more wrong with the PS than
the parts you listed.
Fifth, if you don't know how to test the supply one you fix it, the "fix"
may be short-lived, Sony parts or generics.

Most people without Sony training and without a lot of experience with these
sets would be better off getting the relevant training materials and being
more cautious about testing, or get the set to an experienced Sony servicer.
These "routine" repairs have driven many otherwise decent techs nuts.

Frankly, I would not sell you the parts, either. The $80 labor + parts that
I charge for most of these repairs is a fair price for my experience,
training, and time. You can get the parts from many distributors
(Tritronics, Andrews, Vance Baldwin, MCM, etc) and I am not in the parts
supply business. The shop should tell you, however, if this is the case,
rather than stringing you out.

These are standard parts, call Fulton Radio @ 1-800-248-0898, they are a
Sony parts distributor.

Thanks for the kind words. There are actually quite a few like me that you
will find in this group. If you look around more you might even find some
in your area. My experience is that most markets have at least one
professional servicer and a few half-ass shops.

Leonard:

You sounds like a perfect gentleman; and I do believe you are just by
the way you express your opinion

When I first posted the list, my level of understanding the problem,
shall I say, still in the learning curve. Later, I found out that the
horizontal output transistor Q502 (2SC5148)should be inspected/tested
for failure. And that those VDR needs to be verified intact...

I am actually from Ontario, Canada, where some local TV repair charges
an arm and a leg to fix this problem, then pickup and delivery charges
(heavy 32-in TV), and those CDN 15% taxes on everything add to the
insult! I may as well save the money for a brand new 32-in TV if they
fixed it. For example, a low end Prima 328 costs $CDN 540 versus the
estimated cost to fix of $CDN 300 and changes.

If you were in my local city, I could not be happier to get you or
someone does the job, which I think you quoted a very reasonable rate.

On the other hand, B&D Enterprises (PA) charges $US 7.75 for such
repair kit! Note that the repair kid does not include those varistors,
still for some change I ordered them, as the shipping cost would be
the same. As an electrical engineer working on power supply before, I
did some troubleshooting, repair, ECOs ...etc and thus am not
intimidated by the job. For such a minimal cost on parts, my labor is
free, the worst it could happen is that I... have to buy a new cheaper
TV? In 5 years if it blew, just get another one. The industry seems to
gear to a disposable everything, starting from those inkjet printers,
where consumable costs more the new printer, but I digress

In sum, I appreciate your inputs. I don't see many like you around,
other than usual repair shop struggling to survive, passing this
cost/burden to the average consumers.
