Samsung PN51D550C1XA LED flashes 6 times

[tadziuz]

HI guys
recently bought a Samsung PN51D550C1XA plasma tv which has no picture or sound just red LED in the front flashing 6 times... Same flashes no matter what boards you disconnect. Found one short transistor on X-Main board (30G124) and blown fuse on main logic board. After replacing the fuse (left X-Main board unplugged - dont have a transistor) relay clicks and red LED flashes constantly (1s interval). Should it be like this or should it power up u reckon? Does anyone knows the replacement for 30G124 as the one I found on ebay is available from China which takes ages to post...
Regards Tadas

On a Samsung the blinks mean nothing.
Have you tried the 3-4 jumper test on the logic board?

Place jumper between 3 & 4, and unplug the brown connector.

Do you mean ribbon cable from av board? Same - relay clicks and LED flashes. Don't forget I still have my X-main disconnected ... Thanks for the link. I've seen that before but this is in US so almost same as getting from China

What do Vs/Va measure before it clicks?
As far as a part, you will have to either replace them all with the same part, or find the right part... you cannot sub in a similar part as it will cause uneven power dissipation

I found X-main on ebay and gona buy it tomorrow I was Just wondering Should it power up with disconnected X-main if everything else is ok? Before when the fuse on logic board was blown Va was 0 and Vs used to rise slowly up ~10V let me check now... No Va, Vs ~4-5V
It starts clicking as soon as I plug it in...
