No picture,led blinking yellow and blue

Power saving modes are automatic for some LCD monitors some have setting like after 20 ,30 mins to an hour the computer monitor itself will go into standy saving modes like power led switch indication go to yellow led lighting or the monitor of the lcd screen go blank if ur computer have no pictures for displaying as a screen saver modes.Power saving modes it best for uses if ur computer it on all day long.If u don't touch the mouse or a keyboard the monitor will go in the power saving modes for less electricities consumption for less stress for the monitor electronic components for working to hard for the monitor not to malfuctions sooner or the monitor life cut too short because the computer it on all day.

Hi! I am experiencing the following three

Hi Rafael,

First of all thank you for posting your question here at Fixya.
Please confirm if the brand and model number above is correct.
Blinking of the the LED (yellow and blue) at the front panel indicating that the lamp door cover is not seated properly. This cover will engaged to a micro switch giving the signal to the processor, once it is in open position, the unit will not power up and will experienced that kind of blinking error code. Go back to the lamp door cover and ensure that it is properly seat-in.
3D, 2D, red/green/blue ghost on the picture and letters means that the convergence circuitry gone bad. Symptoms is not connected to the light engine. The faulty parts is the convergence chips(IC). This chips are mounted on the large aluminum heat sink and starts with STKXXXX-XX (X means number). The most common STK chips used on Projection TV's is the STK392-110. You have to replaced them both on the board to resolve the issue(red ghosting). It is necessary also to check the resistance value of the resistors around its circuitry using the multimeter. For more info how to repair a convergence problem, watch the video below.

When I start the computer the Windows XP Logos light up on the Monitor (HP w1907) when the computer starts the Logo disappears and the monitor goes to sleep

If this monitor (HP w1907) is going into sleep mode the normally blue power led will change to yellow. This indicates loss of video signal or possible out of range resolution. If the picture goes dark and the power lite stays blue, you have a backlight malfunction. It can be an inverter power fault but this model mostly has worn out backlights causing a shutdown condition.

I-inc CY199 monitor will not turn on

Hello,

It sounds like you have a monitor with a common problem, we have repaired many Hanns-G monitors with this 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 the monitor. If you are good at electronics repair/soldering you can usually fix the 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 pictures 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. If you can't do the repair we offer a repair service, contact us for more details.

I hope this helps, if so please rate my solution.

Monitor lite blinks from blue to yellow

I bought my monitor last year and had it for only a couple of months and the same thing, it is blinking the yellow and blue led. I can't believe that so many people are having the same problem. I went to the I-INC web site and there is nothing posted about this problem. I think that they really need to address this and let the consumers know what is going on with this. I feel like just trashing this monitor. I ahd to end up buying a cheap bulky monitor to replace it.

Its noting to do with capaitors the EEPROM has been corrupted not sure how this happens as the write protect for the eeprom is under the control of the cpu and not hard wired.
I have repaired three of these monitors all with the same fault no components were required just the eeprom re flashed.
The EEPROMs are very cheap so I will buy a few and pre programm them for others wishing to repair there own monitors.

Look at the Capacitors on both boards, the top of the capacitors will be puffed up,(rounded) if they are bad, change all of these, they are 470uf @25 Volts, normally six on the larger board they probably are colored green made in China of cheap quality. Also change the 330uf @16 Volts on the video out board there are four of these that normally go bad, again cheap quality parts. Also check the AC receptable when you have it apart as the solder job on the connections is of poor quality. This should fix your problem if not contact me for more info.

Hi Adrian
You have previously stated that you might be willing to supply programmed eeproms for I-INC CY199 monitors. I have two that are showing the flashing power light problem.
Are you still willing to provide me with a couple?
Regards

Preston

Adrian, Do you have eeproms to fix this problem?
