Well, this is a quaint problem. My friend's 15+-year-old Samsung SyncMaster 753DFX did not light up when she turned her computer on this morning. After considering my alternative approaches to possibly fixing it and after (possibly) making some display adjustments without being able to see the screen, I decided on the desperation move first. I gave it three sharp whacks, and it lit up and is working. The new problem is a pronounced bowing in of the sides toward the middle (I think it is referred to as the pincushion effect). When I select that adjustment from the menu buttons on the front of the monitor and make adjustments, it does not respond at all. I have a feeling that whatever I jarred into place did not completely reconnect (maybe??). The monitor is probably not worth spending much money on, but if anyone knows anything simple to try (I already tried re-whacking it with no success), I would give it a go.

Thanks,

Tom

Looks like the monitor problem. Try using another monitor to be sure if you can or just replace it was a lower power consuming, lite wight, smaller desk top foot print cheap flat screen. Maybe 2900baht should get a good one. But if money is an issue many TV shops could maybe fix it vary cheap.

Not worth repairing - for so many reasons.

Replace it with a new LED display.

Note:

most inexpensive LED displays

will not sync at >75Hz refresh rate

so prior to removing that old CRT,

set the refresh rate to 60Hz, 72Hz or 75Hz.

This got me in mid 2009 on 2 old computers

when I replace the old crt's

with LG Flatron W1943SB LED units.

Greeted with no display, except a message on the screen.

Solution was to reinstall the old crt,

lower the refresh rate, then install the LED unit.

Actually it surprised me as

I thought the OS would have installed the new display

with a default 800x600 @ 60Hz.

Your milage may vary...

Thanks for both replies. And thanks for the heads up on the refresh rate. That one sounds tricky.

We got the monitor repaired at a local TV repair shop for 400 baht and are back in business.
