Samsung TV repair question.

[Beezle Bub]

I have an analog Samsung TV which I bought in 1998. It is around 32
inches. The problem is the image keeps getting 'squeezed'--the sides
cave in and the image takes on the shape of an hourglass. In the past,
I would have this problem for like 10 minutes but the image would
eventually correct itself. Nowadays, the problem remains as it is.
Anything can be done about this?

Model # is TXJ2766.

Check the East-West / Horizontal Pincushion correction circuit.

And since the problem used to resolve itself in 10 minutes, presumably
as the components warmed up, dud capacitors would be a good thing to
look for.

Or bad joints on the EW modulation diode, if that chassis uses that type of
geometry correction circuitry. Needs looking at quite quickly though,
because if it is a bad joint, the currents involved in the modulator
circuit, can cause quite serious burn-up damage to the PCB

That's what happens when you feed HDTV into a non-HDTV TV Set. It takes
about 10 minutes for the set to correct itself because frame buffers
were a lot slower back in 1998.

That has to take the cake for the worst explanation of a problem
this month. HD signals do not cause an hourglass shape. If this
is a CRT set, you need to check the pincushion correction and
horizontal deflection circuitry. If it is a flat panel display
(doubtful in 1998), I have no suggestions.

I have never read such pure unmitigated bloody nonsense in all my life,
Stick to carpentry or plumbing or baking or whatever it is you do for a
living ...

You can't be /serious/ - I thought it explained the problem of trying to squezze

HD into 32 inches very well....
