Re: Samsung LN40A550P3F 40" HDTV, slow to turn on



Thankyou for the reply.
it never gave me a chance to think about updating/resetting the firmware. Is it possible that cap in the power board is culprit, that provides voltage to MP2363DN as its input voltage is flashing too.

Would it be wise to replace the main board with a universal board?...

Re: Samsung LN40A550P3F 40" HDTV, slow to turn on



Hello!
I got hold of a LN40550A with flashing red issue. power board and caps are doing good and so are the back lights (when tested). The issue is with its main board BN94-01709k (The caps C131 and C102 were replaced with 25v 1000uF by someone)
I replaced these caps and tv worked for a good 30 minutes and then turned off.
Then I replaced MP2363 ic and stock smd caps, TV turned on for a little while and went back to slow red led blinking state.

all voltages of main board keep...
