Sharp Aquaos LC52X20E Blinking Code

[Shipmaker]

A friend of mine got a problem with his Sharp tv
When he plug in the tv a blinking code apperace the power light blinking red for three times fast and the ocd light blinks green slow and permanantly.
So we treid to unplug the power and plug it back the code apperace again than we tried to hold volume + and channel - and plug it back and the blinking code has gone and the power light is permanantly green but again no sound and no picture.
So what was this blinking means? and what could we do do we have to replace the mainboard or may be the powerbourd or T con ?
Thanks for answers?

You can download them and study them in the mean time.
