HP vs17X monitor blue power ligth blinking, nothing on screen

Check for back lighting. The screen will glow.
Sound like the power board is out.

you have three bad capacitors on the monitor motherboard

Needs to got to monitor repairer.

Have you tried to hard boot it ? That means takin the battery out for at least fifteen minutes this usually helps cause it gives the laptop time to reset to the default settings

Hello Robert,

You have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you are good at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts, replace any that look like the pictues and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. You may be able to get the repalcement capacitors at your local Radio Shack, if not there are several sites and the internet you can order from. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.

Try taking on the back of the monitor and pulling the power plug all the way out of it for about five minutes and then plug it back in and restart the computer see if it solved it thanks

Let me know if this is helpful for U

This is most likely the power inverter board in the monitor - this is common in many monitors. If it started taking longer and longer to display an image, and the power light is blinking on-and-off, that's the problem. You can confirm that it's the monitor and not your computer or the cable by plugging in another monitor if you have one to try.

If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors that are replaceable. The board can run anywhere from $50 on up. Depending on how old it is, you may find it better to just replace it with a gently used one from ebay.

A blinking blue light indiactes that your power-inverter board is not putting out what it should. It needs an overhaul which may be a simple as changing out the capacitors on the boards.
It could go beyong that to transistors or even a bad bulb.
It will have to be opened up to do that.
A picture may show visual signs of damage. If you can take one and email it to me , I'll take a look.

HP's are known for bad capacitors in the power supply.
Replacing them is simple if you know how..not so simple if you don't.
Try your local TV repair centre. It should not cost alot to have the capacitors replaced.

Hope it helps =)
