Re: 793S 17" CRT Monitor Problem

Have X2gen LCD Monitor with the same type of problem.

Take apart the LCD screen and reseat all ribbon cables. Make sure they are connecting right. I found a black wire on one ribbon cable that was not seated in the connector correctly.
RESEAT ALL CONNECTORS carefully to avoid breakage.

Look for discoloration on all connectors to see if they was an overvoltage to a short causing the screen problems. If you see discoloration you know you have the connector they cause your screen problem.

Samsung 793S (Black) 17

On these older CRT monitors when you have that type of problem it indicated that the high voltage power supply is not putting out the right voltage to charge the picture tube. As the power supply gets weaker the time to show a picture will take longer and longer. It is not worth repairing the unit because parts will run much more than a replacement monitor.

Monitor is busted!

If your pc works on another monitor. I would recommend you buy a new LCD monitor or a used CRT.

The best solution if your computer works is to buy a LCD screen, I've thrown out my 17" crt screens they aren't worth anything these days. You can get a used crt from ebay

Over here where I live I bought a used crt for 25usd thats was over a year ago.

Theres really no point in trying to repair the screen if its broken, buy a working one or a brand new lcd.

Good luck.

No Display on connecting Data cable of PC

The Monitor is bad, with the CRT Monitors you cannot just replace the connections, because it is embedded into the CRT. So it is probably something that lies with in the monitor itself. Try to connect another monitor to the device. See what the result is, my best guest is the CRT Monitor when bad. Time to replace! Sorry!

Problem in monitor 793s (no high tension,power led is belinking,hearing a sound like contact relay (on then off)

Time for a replacement, CRT monitors are not in the realm of repair, just replacing. You could get a good deal on a used one as these monitors are becoming obselete!
