Sony Bravia KDL-40W2000 two led standby flash Any ideas?

[cheeky2]

Looked at the schematics and see that it is a VD1.8, DE5V/6V Voltage Trouble (DCALERT2)
Anyone had any experience with this power supply and likely location of fault?
 I don't have the TV yet to test the voltages on the power board.
Thanks Anthony

How many times blink LEDs ??

[cheeky2]

Led blinks two times which in my opinion is pointing it to the power supply.
Though it could be something on the main board that is dragging the power lines down. However i don't have the tv yet to test it yet!

A couple of days time i will have it in my hands for testing :)

Error code 2 is usually a failure of the 12V rail. Carefully examine the power supply board and check all pico fuses you find. They can be a tad hard to spot.

I will do so fortunatly my eyesite is excellent i should have the tv tomorrow for a hands on look!

Thanks Anthony

Faulty relays are a common problem with Sony sets, if it has relays check for burnt / high resistance contacts

Well looking at the schematic of the TV and getting the meter out it was determined that the 5V was dropping down after a very short time on the Main Board! It looks like the Q7001
RSQ035P03TR Mosfet had failed! After trying to get hold of it online it turned out easier just to replace the main processor board 1-871-229-12 which i managed to get hold of from ebay at £20!
 So now tv is fully functional :)

 Just managed to order the mosfet at a reasonable price around £2 so will be repairing the original board, though it may take a while for the parts to arrive from China!
Be lucky Anthony :)
