BG800 failure problem

i had a problem with mi smps board and i saw like a spark from focus board,

i have the smps repaired now but the pj gives me some error led on the cpu board

1)StdBY power

2)main power

3)processor cycles

4)error

5)rcu

when i connected the dvd player an error message comes from the green tube

i looked into the tube to see it so i could read it not so right:


FAILURE

> SHORT CIRCUIT

> I2C DU*


the i2c error led on the cpu board was not on so i ask could it be a 12c error instead???

Thanks
