Have just posted this - twice, elsewhere - I'm afraid the sets are getting old:
"I think you are either suffering from a failed power supply or the supply is cycling because of a 'downstream' problem that could be in the high voltage circuit. In each case, the blink count probably would tell you approximately where the problem is located but only a Sony tech will have access to the codes. After all, we are only mortals. "

SEVEN Blinks---High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
KV-32HS510 and KV-27HS420, seven times blink error code shows problem in Horizontal deflection circuit.
There are many possibilities like dry solder joints, weak capacitors, Horizontal transistor short or flyback transformer fried etc.
If you have little experience of TV repair and good solder skills and have necessary tools to test / check defective parts, then you can make it. you also need to have related service manual to see board location, schematics and part numbers.
The 7 blinks indicate an over voltage condition. The high voltage section has exceeded 33,000V. This is generally caused by a bad regulator. I don't have a listing for your model, but there should be a multi-pinned IC attachd to a heatsink marked STRxxx located close to where the AC cord comes into the set. Post the actual marking here and I'll get you the part number and cost. That is the regulator that may be the problem.
There are some components that have become thermo sensitive from age and use. After the defective parts come up to their operating temperature they go out of specs.
Most of the time this type of problem comes from the power supply. Sometimes it is from another board that is causing the shut down.
The fix is to start by replacing the power supply for a start. If there are still any faults, the tech will try the boards to zero in on the defective one. Once he locates the defective board, if it is not worth to service, he will leave the new board in the set.
This type of repair can be in the average range between $200 to the $500 range depending on the exact fault. This is providing that the fault is not inside of the screen itself.
Have you tried disabling SVM (scan velocity modulation)? Often touted as a "feature" of TVs, it's a way of artificially making a picture appear sharp. Totally unnecessary. When SVM (sometimes called VM) is on, it can lead to some color bleeding around edges.

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..
