I have a 795ft plus for 5 years.
I can't turn my monitor on. I have power because amber (orange) led is on. when I press the power the orange led blinking 4 times and goes off for 1 second and so on.I disconnect the signal cable but problem still remain.
I couldn't find any solution in troubleshooting guides.
what can I do now ?
if the problem related to the montor harware please describe the details. !
There is a step by step procedure
1.check the power cord. (try with a new one)
2.check the monitor on other pc, even if it is not working on the other pc, then carry to a service centre.
3.if it is working on the other pc then check the vga slot/card of your pc then
4.try to change the vga card and try connect an other monitor to your pc. so basing on this you will be able to trace the problem.
5.still the problem persists the consult the service centre.

The Line-Out-Transformer is weak and the relay (spark beep) needs to be replaced. It is best advised to get in touch with a monitor technician who can replace the LOT and relay. If not, trade this monitor for a new LCD monitor.
In some cases, such problem could arise if the picture tube's electron gun circuits have become weak!
YOU NEED TO CHECK TO SEE IF THE CAPASITORS ON THE POWER SUPPLY AND MAKE SURE THERE NNOT BULGED OUT OF LEAKING IF THEY ARE THE NEED TO BE REPLACED
YOU SHOULD BE ABLE TO FIND EVERYTHING YOU NEED AT RADIO SHACK FOR LESS THEN 20 BUCKS
My sister's monitor wont turn on at all. She was shutting her system down due to a storm rolling in, and it said windows shutting down installing updates, while she is shutting it down. She turned it on today and the little light came on then it went off and hasn't been on since then. The Tower works fine but the monitor isnt turning on at all. What should she do? She has had the monitor at least 2 years no more then 2 1/2 years! And it is a LG Flatron 20". HELP
YEAH YOU NEED TO EITHER OPEN UP THE MONITOR AND CHECK TO SEE IF THERE ARE ANY BULGING CAPASITORS OR BURN MARKS ON THE BOARD IF THERE ARE EITHER REPLACE THEM OF TAKE IT TO A SHOP AND AHVE THEM DO IT BUT THAT SHOULD SOLVE YOUR PROBLEM
I know that my post is very belated, but I think, will be helpfull for someone henceforth...
First of all, there is one "chronic" problem with LG monitors: solders. Check soldering of Video Amplifier IC303, Flyback Transformer, Q833( ! 210V) , deflection coils socket, Vertical IC601, XTAL X401 and so on...
In Your case, probably the cause of "green, amber, amber" lights is lack of 15V on the Verical Amplifier IC601. DPMS is activated, and monitor does not work at all, even power off.
Replacing Q912 (2SA1273) solve the problem. I replaced him with 2SA1680 PNP 1A 900mW 60V, and all is OK.
This problem is fundamental for ALL 17'' Flatron monitors, repaired by me (over 30).
