hp lcd screen

hp touchsmart 310-2020, i am almost positive that the lcd is bad but can't tell. it has an LVDS 40 pin connector and i think if there is a cable(LDVS 4o pin) that will`connect to the mobo and the other end to a VGA, DVI, etc to use with an external monitor?
anyone?

what makes you think the screen is bad?

The PC powers up. The fan spins, i hear the a bootable cd/dvd disk running. When i connect a USB reading lamp it turns on but the screen is black. Then i thought the mobo is ok the lcd is bad but expensive, so i don't want to buy one just to try. hard disk and memory are good.

a bad power supply will do same thing as seen that a few times on desktops.

I read the same about the PSU but for testing i use a dell with the same tip the amperage was low and the power switch was blinking. Then i use the brick that came with the pc and as i already explain about the hd, hd, memory etc. so you still think the the PSU although powers the pc is still defective?

psu supplies different voltages like 3.3v, 5v & 12v. the fans & drive motors use either 5v or 12v but the motherboard also needs 3.3v.

FIRST LET ME THANK YOU FOR TAKING TIME TO TRY TO HELP ME.
right now i am taking the specs from the ac adapter that came with the touchsmart 310-1020 and they are:
19.5 v 6.5 A 120W. so any other ideas because this PSU is fine.
by the way assuming that even the LCD is good is there a cable that can be connected to the motherboard where the lcd is connected right now but has a VGA or DVI or HDMI end so it can be connected to an external monitor.

that is a power adapter so the 19.5v still is broken down in the motherboard to different voltages. how do you know the power adapter is good, did you use a volt\multi-meter to check the voltage? this is used to connect a laptop screen as an external monitor. http://www.ebay.ca/itm/Compatible-R-RM5251-LCD-Controller-Board-Kit-with-DVI-/271241797794?hash=item3f274560a2

hi, the PSU checks ok with a volt\multi-meter. The link provides for a kit that appears to be what i need to test the pc and find out that the mobo is bad. According to what i read if my LCD is good and i have the right kit then i will need to get my LCD model since this kit purpose is to re-use an screen, assuming it is good.
A bit difficult to understand the instructions.
P.S. I saw this case as "close". I think then it is.
