Re: picture brarred, focus responding but cant improve...
Did u try adjusting the focus knob in the flyback transformer? this device is connected to the anode of the picture tube which produces the high voltage so be very careful of adjusting it. dont touch the wire linking to the tube. thats approximately more than 21,ooo volts dc! good luck!

You cant do anything to improve the quality as its the hardware. you cant change the quality of hardware by using any software. You can download other photo editing tools to alter images but the supplied software is the best.
the color issue is most likely the crt coolant needs to be replaced you can get the phillips CRT coolant replacement kit at the following link which contains the coolant and the instructions on how to do the replacement. http://servicemanuals.vstore.ca/
The crack you hear could just be the speakers or a intermitant ground problem in the audio circuit more likely the spealers if its only on strong Bass
If the input to a HD tv is not in HD format the tv won't display an image very well. Be sure your input to the tv is compatible with the tv's technology for optimum performance quality Also re-check the input source (such as converter box, dvd player, etc..) and be sure you have the correct input/output ports connected properly. Try to reset all yout tv settings back to manufacturers defult specs. When an input signal is sent to the tv most modern tv's have software built in to select the proper format to display the input image. There may have been a mismatch communication error when your tv software tried to "handshake" with your converter box input signals from its firmware. So try a reset solution and re-connect the tv without the converter and see if that helps. If not e-mail me and I'll determine if the tv needs technical servicing.

This is a good indication that there are poor solder connections at the convergence ICs. If you can solder, you can fix this yourself. The convergence ICs are large black ICs attached to a heat sink and will be marked STKxxx. Resolder the pins for these and the problem should be resolved.
If this is an HD set and you are using a SD signal I have seen many disappointed people because the upgrade that takes place in the digital video circuit is far from perfect. It will not look like it did at the store without HD!
