Re: LG monitor problem

thanks ,but i don't think the problem here
i think it from my CRT which it may be low emission
so,the monitor turned off after a period of time

is that correct or there is another problem

Re: LG monitor problem

May be you're right

as for my monitor ( it's OLD ) it sometimes goes black when the weather is too hot ( if I forget to load the air-conditioner or even a fan appointed directly to the monitor )
while it works good in good weather

Re: LG monitor problem

Verify the supply voltage for the CRT.
Also for video stage.
Please use the oscilloscope.

Re: LG monitor problem

Most of the time ist an soldering problem. If you turn of the power (remove powercord) and look ad the print for contacts wich are broken. These are most of the time around the FBT (black coil whit red and white cables to the tube) BE CAREFULL HIGH VOLTAGE.

Re: LG monitor problem

I had the same problem, I suggest you, make a call for the company and ask them, if no help! just take it to the their service support and they check it!
I had the same prob, and finally I changed the monitor.
