The screen on my monitor flashes on and off. The power light stays green but the screen will come on for about 1 second and then go out for roughly 2 seconds. I can see my desktop perfectly when it is on. When I unplug the vga cable, the monitor displays check cable untill it sleeps. Any Ideas?
This is a problem I have seen with a few LG monitors.
Your Inverter circuit is fine (that powers the lights to your screen so you can see the image on the LCD panel) but the monitor does not like having a video signal attached to it.
Hope that helps =)
In general, Sony will have an authorised repair centre close to you. It will be just a normal TV shop that does their work.
The part would need to be ordered in by the shop through Sony and would take 1-2 weeks depending work load of Sony spare parts and also the TV shop to have it back.
Cost wise, the card would be around $70 Australian and then labor on that. This is not a hard process for the shop. Just open it up, old card out, new card in, test it, close it back up.
If you take it to the shop first, they may even find it is just those capacitors causing the problem and then replace those in no time at all. You will save on the part, but the labor cost will be higher since they have to do more manually.
The first thing to do before you goto any shop is contact Sony either via email (check the support section) or by phone. Your LCD may even still be under warranty, and will cost nothing.
Be ready if you call them with the model number, serial number and purchase date if you remember. The serial number is the all importnat one though. They will be able to tell from that if it is still within the warranty period.

That makes sense. The power seems to be good. The voltages are correct and there are no fluxuations. I saved this monitor from going into the trash so it doesn't have to be fixed. How much do you think the part would cost?
