Hi,
The power board is EAX64905001 (2.7), over
internet i found wiring for (2.4).
May be the whole problem is that
i have 3.13V instead 3.5V. When i power up tv
the red led light up for ~10secs, then power off
for 3-4sec, and again power on, power of, etc.
In version 2.4 output 3.5V came from main transformer - D203-
C201- LB201- C209-C210.
But in my case (2.7) 3.5V came from IC202 (NR891D).
In hid datasheet there is only info that from output must
have 5kohm resistor to FB to produce 3.3V but i can`t find
what control and how to calculate output voltage.
I change both capacitor near to LB201, but this did not change
output voltage of 3.5V line - it stay 3.13V.
What other to check?
