LG 42inch LCD TV power board [SMPS] EAY62810501 schematic and test methods
LGP42-13PL1
LED TV Power EAY62810501
schematic
On Condition : In a moment
of Power ON Signal activated, the current of 3.5V output should be limited
within 40mA(Max) at LCD TV condition for stability.
Do not turn “Power ON” Signal on at the load condition of 3.5V output, more
than 40mA.
* Total regulation for each
output circuit includes the results of input voltage variation, load variation,
warm-up drift and temperature change.
* Maximum input Wattage Rating: Under 85W
This Power Supply has
below-mentioned protections.
* Short circuit protection between different output terminals is not
considered.
* Trip point for over voltage indicates the operating point when the output
voltage slowly increases.
* The conditions of Over Current measurement Multi output (3.5V,12V,24V) is nominal load state except an over current measurement.
