Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Don't return the new refurbish tv power supply board,keep it and used it the old one u have it in ur tv it is shorted and dead already.Return those LCD inverter boards though.Should buy a main tv Tuner signal board and replace it too though,that the other board it is causes and it is also dead too.Repair this problems many times before,alway these two boards are dead.I promise u the tv now will have stable power supply again tv will work again.
Sounds like the tcon (timing control) board. Sometimes unplugging the LVDS cables from the tcon, cleaning and reconnecting solves this. The catches on the LVDS cables are easily damaged and must be handled carefully.
Just a copy from Sony:
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.
Option 1: replacing the main board will run you a few hundred bucks for the Board and $300 in labor (or so) to get it installed.
Option 2: replacing the TCON means you might have to replace the whole screen (some TCONs are not available separately). A quick phone call or visit to Sony's part website will be able to determine which you need.
If you need to replace the screen, buy a new tv. The panels are amazingly, painfully expensive.
Now, there's a way to test which one is causing it, but you'll need to be quick.
For this experiment you will need: a screwdriver, a hair dryer, and some guts.
Take the back off the set, fire up your hair dryer and fire away at the TCON board (located at the top; it's a small board under a metal shield--you can't miss it).
Really warm up the metal shield and circuit board.
Now, plug in your tv and turn it on. If you don't see blurry colors and everything looks normal, you know it is the TCON board.
