If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
P-6 : Cyan imaging unit failure P - 7:Magenta imaging failure P -8 :Yellow imaging unit failure P -9:Black imaging unit failure Select Imaging Process adjustment - D Max Density and if the setting value is negative readjust. Check the drive transmission portion of the imaging unit and correct as necessary,clean theIDC registration sensor windows if dirty,clean the contact of the imaging unit connector if dirty,check the high voltage connector for proper connection.If necessary change the image unit or the image transfer belt unit. P -21 : Color shift test pattern failure. Wipe clean the surface of the transfer belt with a soft cloth or change the image transfer belt unit if the transfer belt is damaged.
Depending on how old it is, your probably not going to be able to. You need a SVHS connector on the TV set to connect the computer to it. There are some converters you can buy at Radio Shack that will convert "Composite (this is the Yellow Connector)" to SVHS, but your going to have to wrestle with the cost to do that. You may want to just put the money toward another TV new/used that has the SVHS connector already on the set.
From your description, it sounds like a problem with the blue color. Green LCD=purple onscreen, Red=cyan(baby blue) onscreen, Blue LCD=yellow onscreen. It could be a lot of dust on the blue lcd panel, or worse, might be a burned polarizer filter behind the lcd panel due to excessive heat. If you can focus on the yellow and its tons of yellow specs, its dust. A burned filter however, must be replaced. A technician trained in projectors will have to do it. The filter material is glued to a thin glass panel and is replaced as a single filter. It's a very involved repair.
Your yellow tint issue can be from two different things. One, it can be a setting on the projector itself. Two, or can be the screen you're projecting your image onto. Your projection screen needs to be very white to get good results.
