I had the same problem yesterday and found a post from a former Sony technician that recommended removing the U24 chip from the main circuit board. I did so and now it works fine. The U24 chip is very small, has three pins (one on one side of the device, and two on the other) and is located near the very large CPU "Genesis" IC on the 'A' circuit board. It's sort of halfway between the Genesis chip and another chip marked as U5. You have to look at the board very closely to see it. It's very tiny and you could overlook it easily. It looks like a surface mount transistor and will have "U24" printed on the board next to it. It was a bit hard to find. I recommend laying the t.v. face down on a carpeted surface then remove the back panel and stand. There is a case over the circuit board (which is where all of the video and audio connections go to) that has to be removed as well. Look closely for small screws that go horizontally into the sides as well as they have to come off to remove the case as do the two posts next to the monitor connection. If you're not comfortable doing this then get someone to help but it took about 45 minutes and saved me the price of a new television.

5X Blink - TCON & HFR Failure
The 5X blink protection mode indicates a communications error between the TCON/HFR board and the MT5388 microprocessor on the A-Board.
First replace the TCON/HFR Board if the 5X protection mode blink pattern occurs. If the TCON/HFR Board does not repair the problem then replace the A-Board.

Sony bravia black screen audio ok


It is a LCD set and if sound get it in a very dark room and with a flashlight and the set on look to see if you see a very faint image on the screen.

Almost all these sets use a back light system for brightness---an inverter of some type to power the lights---either the back light is bad or the voltage for it is not present or being turned on.
