(Standby Indicator)

KLV-40/46W300A (WB)     3-6

This indicates POWER Error, Low B error of 12V from GF1(GF2) board. TV Micro
(on AG board) pin150 detects POWER_ERR and shuts down chassis power to Stand-
by status.

TV Micro #150

Normal condition : High  /   Error case : Low

- Check 12V at CN002 #1#2 on AG board. And F200 on AG has 12V or not

- Check GF1(GF2) board.

3-3-3. POWER ERROR (RED 3 Times blink) 

This indicates OVP (Over Voltage Protection) of GF1(GF2) board.

12V line or 6.5Vline on GF1(GF2) board is over-voltage.

TV Micro (on AG board) pin139 detects OVP ERR and shuts down chassis power to

 

Stand-by status.

TV Micro #139

Normal condition : Low  /   Error case : High

Replace GF1(GF2) board.

3-3-2. POWER OVP (RED 2 Times blink)

When it happens;

- Check chassis environment

- Check around IC001 and replace AG if temperature monitoring circuit has problem

- Check panel
