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.

My Sony KV36HS500 Trinitron is doing the same thing. Last night the next street over was hit by lightning. The "7" blink pattern was happening, so like the manual stated, unplug it for 4 hours. Which I did. The t.v. is back up and running fine. It's a nice t.v., better than the plasma I paid over a grand for, that's already shot. It's a good t.v. and good that Sony put in the stand by protection to prevent the t.v. from dying an unnecessary young death. Patience, don't rush it, unplug the t.v. and leave it sit. Also, don't use a power strip, that was my mistake, and unplug your t.v. if storms are in the area, I was too lazy to and now I had to deal with this, in 8 years, only twice did this happen. I'd buy another one tomorrow if they still made them.

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.
