Question about HP f2105 21" LCD Monitor
The power light is blue, there are constantly black screen. If I press the VPN select button, I will get a scrren very shortly, and there is a message box showing there is no signal. But the screen is correct. According to HP's online help instructions, the signal processor should be repaired. But HP told me there is no repair for f2105. They give me a ticket number to help me to buy a new one.
My tv power light comes on,but the screen stay black,and in the back of the tv there is a red light that flashes.

You need a new backlight inverter board.Mine was doing the same thing.Its an easy fix and costs $89.99 for a new upgraded part,that will last much longer and is built better.If you have any questions and are'nt sure,send them an e-mail first,detailing the problem as you've done here,before buying one

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
