Hey.. first post but hopefully lots more!!
I have a philips TV i got in..
Initially it was blowing the internal fuse so I took the board out and on the back was what looked like little burn marks on some of the traces, i cleaned them with isoprop and then put it back together.
Now its not blowing the fuse but still not powering..
Done a bit of research on here and decided to check the bridge rectifier..
First I took readings with it in the board..
1-2=532
1-3=517
1-4=0
2-1=517
2-3=1313
2-4=517
3-1=531
3-2=1354
3-4=528
4-1=0
Then removed it and took readings again..
1-2=504
1-3=489
1-4=1142
2-1=1
2-3=1
2-4=489
3-1=1
3-2=1
3-4=498
4-1=1
4-2=1
4-3=1
Then I tested 1-4 on the board itself with the BR removed..
1-4=0
Where too next or any idea of what the prob is..
Thanks in advance,
Liam
