frequency.
Model(s) Affected: TX-32LMD70A TX-26LMD70 TX-32LMD70
Problem / Issue Very intermittently about once a week at switch on the green LED flickers
(indicating power up) but then the red led flashes constantly on and off at very low
frequency.
Solution: Ensure the firmware of the TV is up to date (these models had an update for poor
start up with 1 blink shut down)
If the firmware is up to date, Check the error code carefully as described in the
service manual for the meaning of the blink codes.
To confirm the error count you can check the last 5 error counts by going into the
service mode.
Go to service mode > access SERVICE TOOL and examine what the entries for
PTCT (protection counter) say.
01 error logged would mean 1 blink = inverter problems (thus check its 24v supply
and drive signals (from DG pcb , DG26 INV ON will be 3V).
Replace LCD panel if supplies and drive is OK
