Question about Computers & Internet
Main Pc Monitor is black but the small green light is flashing...!
I have the same problem with a 1 year old Acer AL 2023! It will eventually switch on but it seems to take longer each time! It's up to an hour and a half now!
I heard one source say you need a new power tube or power tube high voltage converter and another say the problem can be solved by taking it apart and soldering the transistors! I've not tried either yet. Is there not a simpler solution that costs nothing or very little?
Ok for the the pricey one horizontal output transistor or flyback, or both is defective.
Next is your main filter capacitor is leaky or drying up already. Try to check for bloated capacitor.
Third check your signal cable to monitor if it is good resolder if this is wiggling or broken solder. Or just loose connection to socket.
For others, are your CPU is actually booting or you have to check the RAM for dirt. Or if you are using a small AVR, it could choke the unit with power try to connect it directly to power source with the same voltage and frequency.
