Question about HP L1702 17" LCD Monitor
I have a Hp L1702 thats just gone out of warrenty. I am unable to power it on. Ocassionally when you press the on buttom the green LED power light comes on for a second and then goes out again.
This is the third flat panel of this model that I know has the problem.
Can you help
This fix also worked for me.
The caps weren't blown but were pushing out slightly on the top ready to pop.
C922, C923 and C924 were replaced and the monitor works fine.
Lets hope HP used a string of bad components that caused this failure and that it is not a design issue which will cause this failure again down the road on my monitor.
Thanks for the help.

Easy peasy, if you open the case up and take out the circut board with the thick brown and blue wires in it, look for the square thingie with yellow tape on it.look for four round capicitors, (little black drums) look at each one. if one is raised and probably has brown stuff comming out of it then its bust . just replace the broken one. i got one that was going to be dumped in work and did some research. but thats all thats wrong.when i first got the monitor the green light came on for a second and the monitor switched off. when i found out what blown capicitors looked like i took the gamble of taking out my soldering iron. happy hunting. firstname.lastname@example.org if any questions

I have a similar problem with the same monitor. I think it is because I used to have it set up for 2 monitors. Now every time I try to turn it on it goes to sleep right away but works fine on my other pc.
Unfortunately, I don't know the solution but I am also looking for a way to fix my problem...

Answer was correctfor my HP1702, Mine only had 2 caps (1000uf 16V) one of which was blown. Easy replacement and I am not a great solderer, leads were far apart and easy to get to.

Problem is in 1000µ 16v capacitors as said before there is four of them on the board. Best way to fix -> change them all to new ones.
I have fixed three of these monitors and all had this same problem.
