Re: does not power on
Hope this tips can help figure out the problem; If AC mains or AVR is good, review checking the power cable connecting from AC mains/AVR best fittingly. Or try connecting the monitor on different outlet. Just be careful in handling connecting end to AC source always. Try another cable if you have extra one. If the problem persist there might be internal problem on your monitor. Busted fuse or cold solders before you transport causes the problem. You'll need technical guy to check internal of the monitors due to high risk of Voltage Shock. Please be guided.

Power up issues on the T220HD monitor are caused by a failure of the capacitors on the IP-49135b power supply board that this unit uses. The repair is easy, you just need to replace the 7 failed capacitors and the unit should be as good as new. Here is a link to some information showing what needs to be replaced to repair the power supply board.
Hello Richard Strong, Welcome, and thank you for using FixYa! To answer your question: I believe you need to replace the two capacitors that you skipped. Then touch up every soldier joint on the power supply board. Lastly, I would look for the replacement part for the +5V and -5V transistors on the power supply board. They may need replaced as well. If you have an Ocilliscope you may be able to test out where the power is failing.
Yes. Do not turn the monitor off by its power switch, let the computer do the work for you. Alot of times when people use the power switch to turn off the monitor, the computer sees that all of a sudden the monitor has been disconnected from the pc. when that happens the pc sees it as a device beimg unplugged and removes that certain device from the pc's list of things that should be connected, and when you turn it back on the pc sees it again and starts loading drivers for that new part(monitor)
Go to the control panel on the computer and look for power options. On the first page there is power schemes, make sure the scheme is on "Home/Office Desk", below that make sure everything is set to "Never". If you don't want the computer "Hibernating", Go to the "Hibernate" tab and uncheck the box. Hit apply and OK. No more sleepy monitor.
When you got the pc, you should have been given a starter pack with some CD-ROM's in the pack, one of them should be the drives for the monitor, you might need to use anothermonitor to see the instructions, but the basic graphics card should power the monitor enough to set things up, until then you won't be able to adjust the settings.
hi. i had the same problem and fixed it. the problem are the 4 transistors (C5707) one of more are shorted (Q739,Q740 and Q759, Q760). Also the fuse PF751 (3a) has to be replaced in most cases. In my case i replaced the fuse and 1 transistor (C5707)
