Re: Help with kogi F9AH screen

Intermittently displays bright red/green/blue raster then shuts down with led flashing 2, 4 or 5 times
Amazingly this was due to the CRT being faulty !

Blank raster
Replace defective TDA6111Q for Red, Blue and green

Red or Green or Blue screen
Check and replace on crt module : D702, D703, D704 (all 1N4148) replace with type 1N4948T

Dead, led flashing red/green at first, then going to red standby
Replace C604 (1000uF, 16v) elec. cap. It is in the decoupling circuit for the 5 volt supply

Color problems vizio lcd hdtv

If your tv has a custom settings area, first turn all color down on set so picture looks black and white. Now in color settings look for red blue and green color bars. Use the bars until the picture looks as true to black and white as possible. Also, try changing color temp.

Its glittery white because i briten the color but when darken it gets green

you must re-adjust in the RGB (Red-Green-Blue) setting. depending on the brand of your TV, because there are set manually from the TV (you must open the cover of the rear of the TV). and there is a set directly from the remote only, with the open "factory settings", then you can re-adjust RGB color, especially green, not too dominant with the other colors (RED-BLUE). how to set is that you need to neutralize the color, (color TV sets to zero level) so that the image becomes black and white. if the green is too dominant, then Decrease the level of Green Bias or Green Cut off/ G-drive.

How do you adjust color, color seems too green?

There should be colour settings under the "picture" tab in the menu. In the colour settings you can change the level of green, blue and red (the 3 that make white) Here you can scale the green back to make it closer to equal with blue and red

I have a samsung2333hd and want to connect a dvd player using the connections marked pr(red) pb(blue) y (green) when i connect them all i get a redish pink screen then when i connect two of them i get...

OK no problem here. I can help. First reconnect the DVD Player to the tv using the Compoment cables. Match Green to Green,Red to Red and Blue to Blue.. If this is done correctly then you will have normal looking picture. If the picture looks like it is missing the RED color then switch both Red cables. The pix should look normal. Then connect the RED and White audio cables to the audio inputs . Now the Pinkish color is a result of the DVD Player not being set to the "Progressive" setting in the DVD Player Menu. It will help to connect a set of COMPOSITE cables from the DVD Player to the TV's Composite Input. Those are the Yellow,Red and White inputs on both the tv and the DVD Player. This will allow you to see the DVD player menu in case you cannot see the menu while in the Component input. The Pinkish picture should go to a Normal picture.

Hook up of dvd to tv

hey I think you need to use component cables blue green red from the player to the tv, make sure the blue green red ports are also on the tv, note: red yellow white composite cable will not interchange with blue green red component cable or connection.

simplify- blue green red= component
red white yellow=composite

*wires must match colors on both tv and player inputs.

then set your input on your tv to where you conected the cable.

Philips 23PF9966/37 color problem!

Most likely you can adjust it in the Service Alignment Mode (SAM).

Press 062596 followed by the STATUS button (upper left). Navigate to "White Tone", press the right key to enter and select "Normal" mode. Set the colors:

Red = 135, Green = 128, Blue = 133.

The "Cool" and "Warm" menus are deltas from the "Normal" settings:

COOL: R -3, G -1, B 5
WARM: R 2, G -3, B -13

Press the "MENU" button to return to the main menu, then the "Power" button to turn the TV off.

No blue color, green replaced blue, white is yellow/green


If the set is hooked up using Component cables (red, green, blue), then check to make sure the cables are hooked up correctly, and not defective (change them out). If the color problem remains, then the problem may be in the Optics block of the television (which is not unheard of in this unit).

If the menu of the TV displays blotchy discoloration, and the discoloring is the same for every input on the tv (stationary), then it is the Optics, and the optics need to be changed. It is not the easiest job in the world, and the block itself is quite expensive, although the unit my be under an extended warranty from Sony. Contact them directly to see if you can get any help (cost or service-wise). Hope this helps...

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

Check settings first to make sure no one changed anything out of the ordinary. Are the shadows that of a color or darkened shadow? It could be out of convergence, which can be corrected in the menu - or it could be low quality video cables to. Also, if there is no green, does a white color show up when you're in a menu mode (Red+Blue+Green = White Image)? If so, then the green picture tube is working and it's just a color adjustment, otherwise you may have to invest in a new green picture tube.
