Having problems with your LG Computer Monitors ?

"LG monitor not starting when cabinet closed"

\015 I have a LG 221U model monitor which is not switching on regularly. I opened the cabinet and it started to work and after I close it again doesn't turn on. How to service it? I already got a schematic for LG 995U model it says, to replace Q901 or Q902. Is it the same in this too?\015

Answers :

It sounds like you have intermittent solder connections that are causing problems. With the back on, the board is flexing enough to make some connection(s) fail. Use a strong light and a magnifying glass to examine the solder side of the circuit board for bad connections, especially around parts mounted on heatsinks.

I have a 3 yr Dell UltraSharp 1905FP LCD monitor. Recently, when I turn it on, the power on green light would blink continuously for about 1 minute with no picture before the light become steady green and have picture (everything working). Now it is up to 5 minutes. Other than waiting for the monitor to display the video, everything is fine. It acts like it is waiting for something to warm up. Does anyone know what is the problem? Thanks.
