If you are using auto focus the green must go along the with the other two automatically.

If you are using service alignment procedure and does not line up, then there is probably a fault on the convergence board, usually a convergence IC that is defective.

    If red and blue do not converge with green on autofocus, there is need for a convergence setup procedure. If red and blue do not converge with green during convergence setup procedure, then you may have a fault.

Hey it sounds like a convergence IC problem and the IC*S would need to be replaced to repair the problem.

My Toshiba remote control se-r0077 sometimes works to control the DVD player and other times it doesn't. I've tried new batteries and the problem still persist s


One of the best ways to check if an infra-red remote controller is working properly is to look at it using a camera. (a webcam or phone camera will work) The camera will see the infra red radiation as visible light. If the LED lights up (on camera) consistently when buttons are pressed, then it may not be the remote at fault, but rather the receiver in the DVD player. Most of the time though, it IS the remote control at fault, and these are usually easy to get working again.

Couple of things to check are:

1) the battery terminals...
Batteries can leak and corrode the terminals in the battery compartments. Signs of this include rust, green coloured contacts, or a crystalline deposit. If you see any of this then clean the contacts using metal cleaner or some methylated spirit and cue-tips.

2) Broken wires connecting battery terminals to the circuit board...
The soldering in some remotes can be rather poor, and wires can sometimes come loose, especially if a remote has been dropped or bashed about a bit. Unscrew the remote and check everything is connected properly


3) Dirt under the buttons...
This can prevent a button from making contact with the circuit board properly. Unscrew the controller and separate the rubber button pads from the circuit board check for dirt both underneath the pads AND on the metal contacts on the circuit board. Clean as required with methylated spirit and cue-tips and then reassemble.


Hope that helps!

The color on my TV is all pink. I have tried a hard reset but it didn't help.


Your TV has lost a GREEN color from a basic color palette (Red-Green-Blue). It is often caused by:
- damaged LCD cable (which connects the display with a signal board inside the TV),
- damaged video signal cable (ex. SCART, HDMI, VGA),
- damaged video processor (on the signal board).
I can't give you a more accurate answer, because I don't know what is your TV mark and model and, in what situations you have the problem.
