Repair manual I have a G220F M/N VCDTS23852-1M monitor that tells me it will shut down in 5 seconds (then does) The green light lights for a brief moment then goes and stays yellow with a black screen. I need a service manual and schematic.

THe problem is in the set top box. Or common called the tuner box. IT looses the 5 volts to the main display and thus the monitor will go into a shut down state. THESE boxes are factory repair only and must be sent off to repair.

Annoying! happens to us too frequently, but this works. We ended up buying a new one and returning our broken one after owning for three months From Manual:) 5. Turn on the Nursery Unit using the On/Off switch on the side. The green power light should come on. 6. Within a few seconds, the Parent Unit will lock on to the Nursery Unit and the top four (4) green LEDs will shut off. A second later, you will hear a series of beeps and the connection LED should change from red to green. Your monitor is now ready for use. 7. If the top four (4) LEDs do not shut off, power off the Parent Unit and the Nursery Unit and repeat steps 4 and 5 above. 8. If the connection LED on the Parent Unit does not change from red to green and the unit begins to beep, press the channel "ch" button on the Nursery Unit. Within a few seconds, the Parent Unit should lock in on the Nursery Unit and the connection LED should change from red to green. You may hear an audible beep during this process. 9. If the Parent Unit is still unable to lock in on the Nursery Unit (connection LED will be red and the unit will beep), power down both the Parent Unit and the Nursery Unit. Wait for 10 seconds then hold the volume down button on the Parent Unit while pressing the On/Off switch. When the unit powers up, you will hear a single beep and all of the soundlights will illuminate. Release the volume down switch and within 2 seconds you will hear two beeps and all of the Sound Light LEDs will stay lit and the bottom LED will be red. 10. Repeat steps 5

Do the self check it should have: when shuts down and green light goes out: On the front of the set press and hold both input and menu buttons at the same time for at least 5 seconds and then release both.

Power light on set should blink a two digit error code: like 2 blink,2 blink, pause and repeat it at least 5 times total.


Let me know what error code and I will tell you what it means.

Update your video card.The 3.34 power supply is fine. Dont go over 3.75 but you can stay just under.

You are more likely to have bad capacitors problem in the power supply, inverter circuits. I would look for bad caps first. Look at some of the sample here: http://s807.photobucket.com/home/budm/allalbums

pl. first check all connection properly because losse connection is one of the reason. if connections are proper then i thk there is problem in your windows xp so reinstall it. OK

Bad capcitor in the psu would cause this to squel and even pop so have it looked at you be glad you did.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

It sounds like the picture tube in the monitor has burned out. Time to replace.

Go to you www.youtube.com and you may be able to find helpful videos on this. But if you bought it new it is under warranty and they will fix it. You just pay for shipping.

This sounds as if you are using the hibernate feature in windows reboot it and reset the power options to hibernate never check the vid connection as well
