Black screen with a flicker`

Sounds like you have LED backlights that are going bad and the strips need replacing, its not a real easy job but if you watch some youtube vids they show how to do it.

can you try each component by themselves?

I switch on my PC, ensuring that all cables, leads and power supplies are connected properly. The tower powers up no problems at all. I switch the screen on, the green led lights up, the screen is completely black. A blue box appears centrally on the screen with the text 'power saving mode'. The green led light turns amber and then the screen just goes black.

Please don't suggest going to control panel, as I can't get that far.

PLEASE PLEASE CAN ANYONE SUGGEST ANYTHING give me

hi

what you are experiencing is that your screen bulb is burnt.the screen bulb is what lights up your screen, its just like a fluorescent tube,when it is burnt it flickers for a while and it later goes off.. the only solution is to change the screen bulb as soon as you can

goodluck with that!

check your monitor's connection, its power and VGA connection to cpu, the cpu may be good but you just see black screen bec. your monitor remained off. please bring it to HP service center for more help

You've got components that have gone bad, probably from age and the normal heat inside a CRT monitor case.

I hate to say it, but it's really not worth fixing. You can usually find a used but working 17" monitor for under 20 bucks.

Its a problem with the lcd and the cost to replace the screen is more then the cost of getting a new monitor.

I've had a similar problem with my 173v monitor since I bought it a few years ago. When I start my computer, Mac or PC (I've connected it to both), the screen remains black and the green power light flickers once a second, almost like it's twitching - it's different from the blink it makes when the computer isn't turned on but the monitor is. Like kronem, I have to unplug the line from the monitor to the computer, wait for the monitor to register no input, and then plug the monitor in again before it displays anything. I've never figured out a way around the problem - I hate it!

HI. I had the same problem with mine. It would flash the screen on for a split second and then turn black, the whole time the power light remained green. Upon opening up the case, I pulled the combo power supply board/inverter board out for inspection. I noticed one of the capacitors had a bulge on top indicating it was bad. It was the the 680uf 25v capacitor. I desoldered it, and soldered in the new one. After hooking everything back up, bingo!! Monitor now works perfectly. I couldn't find an exact match to the capacitance locally, but I had a 1000uf 35v cap in my utility box. It worked fine as a replacement. You can usually go within 30 percent of tolerance and be alright. Just don't go under on capacitance or voltage. I hope this helps.
