    I read somewhere on this board that those device can be bought cheaply. I would really appreciate if someone can tell we where and at what cost? And also if they work well? on what kind of connection can i use this? Does it affect the signal in any negative way?

    I second Robert's motion. I've got a Sony KV27-FS13 WEGA TV which exhibits some red push. I've read about these attenuators, and I'd also like to know where to purchase them.
    Robert, I hope you don't think I'm hijacking your thread by asking about a specific TV. I hope that anyone who answers would also address what would be best for your TV as well. [​IMG]

    Makeshift ones can be hand built with components from radio shack within 2 minutes.

    They include the variable attenuator and two coax to rca adaptor plugs.

    The Sony should have an AXIS parameter in the service menu to address the red push.

    regards

    I second Michael's suggestion.

    I have seen all the red push remedies, and this one looks absolutely NO different from any others, including the regular service menu remedy, and the I2C interface. NO degradation in video quality. And cheap.

    Micheal do you have a plan to build it, or do you have some prebuilt up for grab.

    The red push attenuator is 3 pieces bought off the shelf ... takes 1 minute to assemble ... screw the two adaptors to the attenuator and you are done.

    Adjust the knob on the attenuator to find the right mix of red reduction.

    Regards

    I tried the radio shack variable attenuator with my Sony 53HS20, but quickly decided against it because I did see some degradation in the picture quality on my set. Others noticed it too. Much cheaper and more effective to just change the axis parameter in the service menu to 1. The picture now looks great after doing this and adjusting the hue control a few notches past center in the green direction.

    Here are the parts from Radio Shack:

    RF Signal Attenuator - #15-678
    Standard F Adapter - #278-255
    F-to-Phono Adapter - #278-290 or #278-260 for right angle
    1 ft coax cable

    I think I got the correct model numbers for the adapters, but I just did a quick search on RS's website.

    Total cost should be around $11.

    Best regards,
    ~~Nathan
