This is a problem with the regulator circuit. If you are comfortable with soldfering, you should be able to repair this yourself. I'll look up the specific parts that require replacement.

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with
troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one
circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

Sony FD Trinitron WEGA KV-36FS120 36" TV

Apparently, channels have to be autoprogrammed first before those buttons will work.

Our TV is 4 years old but we never used the channel buttons bc it was always hooked up to DirecTv thru video input. SO when we disconnected the TV to sell, we thought it was a problem.

Sony Trinitron KV-36HS20

I have this set also..
When you set up for an HD signal (1080i) it is broadcast in 16:9 which is a widescreen format. The Sony set is a 4:3 format (more of a square shape) which means the black bars at the top and bottom appear so that you get the widescreen 16:9 format to appear.

This is one of the main negatives I have about this set, however, I can't really complain as I have had it for 6 years and it works great.

I never knew about the other format until I got an HD receiver from my satellite dish provider last year.
Hope that helps explain it for you..
