Turns on for 2 seconds then is black no respond was fine last nite
was also flashing on off
The problem with the monitor is the power inverter board. I took my monitor apart and tested all the power outputs. The ones going to the main board where ok but the ones going to the backlight where different. I changed the three capacitors on the power board that where located between the two heat sinks I think it was the 1000uf and the two 470uf. They looked ok but when i tested them they where off. Next on the opposite side of the board with all the little componites there are a few dry joins that you have to resolder. If you cant find then you can just resolder the whole back board it should only take 30min. If you have no idea what i am talking about i would not sugest taking the monitor apart.
I have the same monitor and have dealt with this for some time now. I think it may be a problem with the monitor not letting your tower know to look for the correct video source. The problem became much worse when I started using an HDMI cable. I think it may actually be my p.c., because when I shut down my tower and pull the power plug from the back of the p.c. for 10 seconds or so, it fixes it every time.
Timezone88, hope you get this since it is an old posting. I just replaced all the caps on my power inverter board. I have 10v comming off the board but do NOT have any 5v. Any idea what component creates the 5v? Do you have a schematic for this board? thanks
When you say it was flashing on and off do you mean the power or the picture? If the picture it could be a fault with one or both of the rectifiers otherwise maybe something wrong on the power supply. Sorry my guess could not be a bit more accurate, if you can please write a little bit more information. Good luck.
I know I will sound like an old man saying this but the quality of components they use in equipment nowadays is not like it used to be. For example I know from experience that some of the surface mounted capacitors they use in this particular monitor there are better quality ones around, but then I guess the price of the monitor would go up and as always we end up footing the bill. Like I said before a lot of LCD monitors have high speed low loss rectifiers and its a mystery to me why a lot of them keep on failing. As soon as I find out more will be happy to share. Sorry I could not be more help.
Lol and thats exactly why that say "you gets what you pays for" is so rife nowadays. I wouldn't mind if the companies wanted to charge us the Earth for a reliable product but even that is no guarantee.

Same problem, star for 2 seconds and then black. If you remove all connections and turn it on it suppose to say no signal, well I dont see any message even when there is no signal input.
thanks for the solution, its not the power source , because I have tried different power outlets, when the monitor is connected to the comupter it turns on flashes to the gateway logo then goes black,then sometimes flashes to my login page for two seconds, the monitor is only five months old,what could cause it to burn out ?
in was pluged into a surge strip. putting in a box to back to gateway.
thank you very much.
your'e right thats why the monitors are so cheap now ,they have comprised on quality parts, an they hardly give any warrentys ,they are becoming throw aways.
The monitor was fine last night when I went to bed. This morning when I turned it on, there was a quick flash and nothing. I've tried plugging into other outlets and it's not turning on at all. I've only had this monitor for seven months and I'm not happy. I'm using my old laptop which is useless as all the files I need are on my desktop which is inaccessible without a monitor. I guess I'll have to buy a new one. I don't think I'll go with Gateway again.
I have the same problem. Last night the monitor was working fine. When I got up this morning and turned it on, there was a quick flash then nothing else. I've tried plugging it into different outlets and it isn't turning on. I've only had this monitor since June and it's a shame that I'll have to go out and buy another one. I doubt I'll buy another Gateway.
same thing, woke up the next morning it blacks out...like i wait for my computer load compeletly then i switch it on...and it just turns on for 2 seconds and then it blacks out....-_-....i guess eh?...get a new one?
Monitor flashes the Gateway logo upon startup, then goes black. Occasionally, it will display the login screen for maybe 2 seconds and then go black again. It is less than a year old. It does NOT power off, the power remains on.
I have the same monitor (Gateway HD2200) with the same problem. I've disassembled it. The LCD panel is made by Samsung (model LTM220M1-L01). The LCD portion is working - I can see my computer's output when I use a different light source. The backlight flashes on momentarily then goes black. The data sheet indicates that the CCFLs are driven by 760Vrms. My meter won't go that high, so I can't check it. All DC voltages coming from the power supply are within spec (+5v and +10v). I don't see any burned or stressed components on the power supply/inverter board.
Any ideas?
