Hi,
the problem with your monitor is the poor solder of the red drive transistor which is located at the crt socket of your monitor the white one with approximately 9 pins. try soldering all of the components in the crt socket board.

Advent tv displays green


If you are saying no red: The model indicated here Recoton Advent Advent Q1435A TV is a 14 inch set.

first it may be cheaper to replace than repair--That said if no red look to the small circuit board at end of picture tube (it plugs onto the tube).

It will have either individual output transistors or a single IC.

What (if only one color missing) I would look at is the bottom side which faces to the rear---a circle of solder connections--possible one is broken--there will be one for each red, green, and blue--not always easy to see but if any of the solder connections look cracked or even broken loose-----

Advent 5401 I have 6 split screens on the display advent 5401 i format the HD I removed the HD and still have the 6 split screen i think bios need to update or reflash can i get the bios for this...


I think the 'split screen is actually your wallpaper
To find out if I'm right - if you right click the desktop - choose properties, then desktop.
On the right side of the window that opens - look at the middle button, it probably says Tile. click the arrow to the right and choose Center. Now click O.K.
Your wallpaper should now be one 'screen' probably with a coloured border around it.
Cheers.

ADI GD-166G SCREEN HAS GREEN COLOUR DISPLAY


hope u r a professional..as u r handling chip-level repairing of monitor, knowing itz hazardous n dangerous..

however, check thoroughly for dry soulderings..(esp. at the crt base)..[this chance is maximum]..
see if the base is loose or faulty..
yes, it can b the 'chroma ic'..but don't ignore the associated components..(esp around the base)..
check video amplifier n sub section..
the colour diodes, transistors n resistances at the base..

for better supervision contact ur system admin/vendor....

Is this TV digital ready


According to http://www.dtv.gov/consumercorner.html#faq9

How can I be sure that I am buying a digital TV (DTV)?
By law, beginning March 1, 2007, all television reception devices (including TVs, VCRs, DVRs, etc.) imported into the U.S. or shipped in interstate commerce must contain a digital tuner. Retailers may continue to sell analog-only devices from existing inventory, but must prominently display on or near the analog-only device a Consumer Alert label with this advisory:

What is the difference between “Integrated” DTVs and DTV or HDTV “Monitors”?
An Integrated DTV set is a television with a built-in digital tuner (also referred to as “a DTV”). A digital tuner is also sometimes called a DTV decoder or DTV receiver. If you have an Integrated DTV, you will not need any additional equipment, with the exception of a broadcast antenna (either a rooftop antenna or “rabbit ears” connected to the set), to receive over-the-air digital broadcast programming. Integrated DTVs can also receive and display analog broadcast programming, so you can continue watching analog broadcasts.
In contrast, a DTV Monitor is not capable of receiving digital broadcast programming without additional equipment; it is simply a display device without the processing capability for DTV reception. A digital or HD set-top box must be connected between the antenna and the monitor to receive and display over-the-air digital or HD programming.
If you have a digital or HD “Monitor” and would like to purchase a digital or HD set-top box to view over-the-air programming, confirm with your retailer that the set-top box is compatible with your Monitor.

Red colour missing


hello
red colour if missing from mother board then you can fix it from graphics properties of your mothrboard driver
but red may also due to monitor,there should be black colour appeaqrs on screen instead of red.
to solve this you have to take your monitor from where you have purchased
if it is in warranty or gurantee then dont take to third party
the fault in monitor may be due to
fault in monitor cable
also check that cable is not loose
try to plug the cable on cpu again
another fault is inside the monitor
also try to on monitor using detaching monitor cable from cpu,message come on monitor ,if in that message red colour appear,then monitor gun is ok
and problem is in monitor due to desoldiring
if you know about soledring than you can fix this problem yourself only if you know otherwise take it to shop from where you sold it
