Syncmaster 793 shacking picture. Help.

[vlad777]

I have Samsung Syncmaster 793 PC monitor
and the picture is shaking or waweing oround
the center just a litle bit but very notecably.
It is like when degausing but smaller in scale.

This one should not end up like the TV from my
previous post here so I will wait for your replys
before I do something so please help.

I took a wild guess and visually checked the capacitors
and they seem fine.

Many thanks.

I have barely touched a few capacitors and
the problem now seems to be gone.
So I suspect a cold solder somewhere.
Could it have been the anode cable contact
with the CRT.
I dont expect this to last I must find this cold
solder and fix it also because it is cind of hard
to get the case open.

I dont intentionaly wish to seem stupid but
for the sake of people on the net I will reveal
my mistake.

The problem was not at all in the monitor but
in the small PSU near the CRT base that was put on top.

But this means that the monitor doesnt fully comply to
the part 15 of the FCC rules.

Why not?, and what is part 15?.

It's your ancient 17" CRT monitor asking to die. Just hit the local computer dump, they're full of working CRT monitors that can be had for a song. Better yet get a much more energy efficient LCD display.

edit: Since your TV set seems to have also died recently might be an idea to look at LCD TV/Monitors with ATSC tuners, HDMI & VGA inputs. Two old busted TVs could be upgraded into a single nice modern LCD.

Took this of my keyboard:

Operation is subject to following two conditions:
(1)This device may not cause harmfull interference and
(2)This device must ACCEPT any interference received,
including the interference that may cause undesired operation.

I happen to like CRTs because color is the same from any angle but I am going
to like LEDs even better.

Presumably that's there to comply with FCC regulations?.

Ok so go buy an old CRT TV and or monitor off of Craigslist. You can probably get it for less than the parts to fix the one you got, possibly even free. I saw a 17" on the curb this morning for garbage pickup. Good LCDs have very high viewing angles, crappy ones don't.

CRTs still have better colour and a faster response time than LCDs.

LCDs are sharper than CRTs of the same resolution and use less space.

LEDs (real OLEDs not an LCD with an LED backlight) are better than both LCDs and CRTs but they are expensive and don't last long.

Who still makes CRT TVs? Does anyone?

Sorry English is not my native tongue so your question eludes me.
Please elaborate.

Many thanks for the advice but I thought that this is a 'die hard fix it all forum not looking for easy fix' .

The wording you posted means that it meets the FCC regualtions.
