Windows 7: Fixing an LCD monitor - stays on for two seconds

Fixing an LCD monitor - stays on for two seconds

If this is off topic please move it to the right board. So I had an off brand LCD monitor whose manufacturing date is unknown to me, lets say its 5 years old. It would turn on for several seconds and then shut off. I read up a little and found a trick to reduce the brightness. Working with a menu for two seconds at a time is tricky, but I eventually notched the brightness down to zero and guess what - it stayed on! It was just really dim. What I read may be a cause of the is a bad / dying capacitor. So I popped it open and scrutinized every capacitor to look for bulges, brown areas and / or leaking electrolyte and nothing.

My question is: are there any other replaceable components that may cause the issue I described? Is there another way to find a defective capacitor without unsoldering and dsicharging / testing every one on the board? Signs are pointing to me throwing it in a dumpster

that is more likely an inverter or backlight than a cap? so you don't have a model at all for it?

Its made by "TPV Electronics co", very generic looking, model T1780PI. Could it still be a backlight if it was at full brightness before? There was no flickering or dimness until i turned down the brightness, then it stayed on past two seconds.

i don't know enough about monitors to know sorry. i bet it is the backlight though as it does not flicker at all right its just dark? probably cheaper to get a new monitor then repair it.

2nd monitor added but goes black after a few seconds..
I just added a 2nd monitor today to my comp, a Philips 109s. It turns on fine, displays the extended screen but after maybe 7 seconds, it goes black. If I change something within the screen res section(ie landscape to portrait), it fires back up, but goes black again in a few seconds. When the 2nd...

Computer POSTs but only stays on for a few seconds then shuts off
Hello, I feel I should mention that this build previously didn't POST, but I took a look at the processor and saw it had a few bent pins. I tried to straighten them out as best I could, refitted the processor (this took a little bit of persuasion). Now my computer POSTS, gets past the...

Monitor goes blank before log-in screen, stays off
When I boot-up my computer, it takes about 2 seconds longer for the monitor to turn on then usual, and right before the log-in screen the display will disappear, and stay off. The PC continues working normally, as far as I can tell. What precluded this issue? Why, I haven't the foggiest....

Monitor light stays orange when booting new build
Hey guys. I was finally able to get everything I needed to build a PC, but when I put it all together and turned it on the monitor does not respond. I checked the cable, even tried another one. I also tried switching out memory modules. I reseated the video card, too. All of these...

Monitor stays blank when turning it back on
I am going to preface this by saying that this has *nothing* to do with restoring from sleep or hibernate modes. In searching for an answer to this issue, I found way too much related to that. My problem is simple. Occasionally (~50% of the time) when I turn the monitor back on after shutting...

When the computer does then eventually...
