Problem seems in back light inverter board and putting TV in protection mode and led flashes.
You can get inverter board from Shop Jimmy.
Please call Shop Jimmy and ask inverter board as currently it is not in stock.

    if so the bulb is blown or there is some moisture on the board or circuits projection T.V's can blow very easily and same with Rear-projection T.V's they shouldnt be used with video game consoles and should be left on with a constant picture that never changes.

HAVE AN BLINKING CODE OF 2 SHORT 3 LONG UNIT ITSELF MAKES A (POWER) CLICKING NOISE WHEN I TURN ON IS THIS SYMPTOMS OF A T-CON BOARD REPLACEMENT OR PERHAPS A POWER DIST. PROBLEM


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

Run the diagnostics.

With the TV power cord plugged in, press the 'INPUT and 'MENU' buttons at the same time -- use the buttons on the front of the TV, NOT the buttons on the remote; a diagnostic Error Code Operational Check will begin, utilizing the 'POWER ON' LED (the green 'POWER ON' indicator light).

There will be a pattern of two sets of flashes, with a pause in bewteen flashes; this sequence of flashes will be repeated a total of five times.

The Error Code designations are listed below:

Error Code Description
12 No eror has occurred.
21 X-Ray Protect circuit.
22 Short Protect circuit.
23 Horizontal Deflection failure.
24 Vertical Deflection failure.

I hope this information helps.

According to Sharp it is a software problem. Engineer came, installed software update ,10 minute job.....TV worked fine for 1/2 day unfortunately: Then images turned black and white in all channels TV turned itself off, and stanby and OPC buttons started flashing. When TV came back on its own 10 mins later , screen had 2 large square staines superimposed in image (as if it was a burnt screen)...Engineer will be back next week...all quite sad really for a new TV.....will keep u posted
