Hello,
This is my first post to this forum. I was recently given a Bush 42" LCD LT42M1CFA as it didn't power on.
After some investigation I found that the 2200uF cap on the 5V standby circuit had failed. Replaced and all is well.
I am using HDMI 1 input and the set is working but I would like to change the color temp settings.
The circuit is the same as a Haier and the same as a Sharp LC-42SB55E. I can get into the service menu using
"062596" + display key.
The color temps are set at:
CLR_TMP_R 122
CLR_TMP_G 116
CLR_TMP_B 122
I would like to set the Green to 122 and although it appears to change it reverts back to the old value
after a power cycle. I can't seem to get it to write permanently to NVM.
Can this setting ( when using HDMI 1 ) be changed ?
Is there a special code to write to NVRAM ?
Note that for "TV" input ( Freview Tuner ) the color temp settings are all at 122.
Thanks.
