BN41-00542A Samsung
Hi,
got a samsung le46m51 with a bn41-00542a power supply,
got some bad reading from voltage regulators probably, would like some guiding to find this problem, the tv has no pictures,
anyway,
i read some thing about the power board hot side should have 160 volt, I read 100 volt.. se picture.
and on the ribboncable from the powerboard over to the logicboard, its som high reading on the 13 volt connector (the only one) on top side. it shows 15.6 volt ,
and 5 volts shows 6,45. but the 12 volt is correct.
and visually sjekked the board and no bulged caps, but changed 5 off them just because i had some at home, but no change.
so on the main board (logic) its some offset on the reading too,
from bottom to top it shows as the picture of mainboard
0, 3.26, 6.45 on first regulator, second 0, 1.79, 3.24 third 0, 5, 7,93. forth 15,57, 0 , 8volts.
the ribbon cable to the tcon from mainboard, on the rightside has 0v output.
so checks som electro caps on power board, but wonder if the 100 volts reading could be a problem on trafo, any ideas ?
best regards niklas.
