Re: Philips 50PFP5332D/37 TOUGH DOG as they use to say

For me knowledge and understanding about how things work is very important,i dig a lot on this board few months ago and only found this diode as a problem,however every case could be different.
At this point is your decision,good luck and inform us about final result.

Look at the two isf104, d8028 and d8031

Re: Emerson LC401EM2F

Ok, problem solved.
After a few days troubleshooting i found that the problem was a broken ribbon flex cable,the connecting the power supply board with the main CBA AV Board.
Was not visible damage,was broken internally, however testing continuity,wasn't any signal,so carefully i inspect it,found the problem and repair it.
I put everything back together and bingo,works like new.
Thanks guys

Re: Emerson LC401EM2F

Hi guys,thanks for the good info in this forum.
I need some help with this same board,it was blowing the fuse and i went checking everything explained here.
this is the list of parts changed:
Rectifier diodes 3 were short,replaced all 4.
D1208 Short,replaced.
As the manual i have the 4.3v all good buy i got nothing after q1201 and q1202 going to the relay.
My question is:
Are those transistor in charge of the power on cycle,or is any other part could be bad?

The fuse do not blown any more,i have...
