Hi Rey,

Hope this helps you like what I did to resolve this kinda problem. If you can manage to open the chassis/cover check first if the HOT (horizontal output transistor) is good, if good check the SMPS (switching mode power supply) primary and secondary side if there are short filter capacitors, diodes, transistors and open resistors. Major faults to consider is by checking the load of SMPS, control circuit, driver circuit, feedback ckt.

Please let somebody to assist you (a certified technician) how to open the chassis safely due to electric shock. Please be guided accordingly.

Best regards,
Rosener Guyano

Whats the problem with no picture on the monitor but the cpu is working


Can you observe any LED lights on the monitor panel when you try to turn it on. If no then check your power cables. If you can see the LED lights but screen does not show try to unplug the VGA/HDMI cable and clean it by blowing air through the plug and then reconnect it. Also try to turn on the monitor without connecting it to the monitor as this will verify if the monitor is OK because if it is it should display a message to check the input signal or no input signal is detected. If it does and you are still not having a display then the problem is probably in your CPU and more specifically in the VGA card.

Monitor in on/off loop. If hold select button down you can see the PC is diplaying but monitor keep going off then on. Also can hear the relay clicking in the monitor.


That is a bad one. Sounds like you need a new relay. I know that is no help. Check the power cord, (believe it or not, they can have too little power going through if they get damaged or weakened by something). Check CLOSELY the video cable to computer connections. touch the ends and nearby cable ends while observing monitor to see if it flickers at the same rate of your movements. Try another monitor to see if it does the same thing. I can't help with much else on this. Good luck

When i turn my CRT on, after a few seconds my screen goes blank, then displays again, while this thing is happening, i can hear something switching... power led is on(green)... even when the display goes...


It sounds to me that the monitors power supply is dying. I would replace it with a different monitor as soon as possible. I would consider this a dangerous situation, and a possible fire hazard.

Thanks for using FixYa,

Hope this helps,

Eric

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!
