Re: 47ls4500 screen has rainbow color.

you need to use a system which processes the wav file "as is" and doesn't "modify" it for "post processing" (ie. sending it thru a blue tooth process isn't going to help things). Further, your DIY IR probably needs to be very close to the receiver as freakaftr8 found that the output "amp" of most "head phone jack players" may not have enough juice to drive the leds directly so the output "signal" is somewhat weak.

Hi, in the past i have tried too the wav file with a cheap tablet with the volume at the very maximum and a single output led with a generic clear led, i suspect that must be used a specific led took from an lcd era LG remote.. i have'nt any so i can't try..

Glad to hear that it is fixed, so now you know that bad Gamma can be due to bad Gamma Voltage reference IC or mismatch LCD setting.
Aren't you glad it is not bad LCD panel?

Thank you burn

I highly recommend this clone Factory service remote to everyone.

Now I'm going to go inside all LG TV service manu. see what's inside.

I did change EEFL TO EDGE_LED (THIS TV IS EDGE TV) but nothing happened. I've changed LVDS form 10 bits to 8 bits I always thought pictures may be down grade.

Pic1 is IN START MANU
PIC2 IS EZ ADJ MANU
PIC3 IS EZ ADJ TOOL OPTION 1
PIC4 IS EZ ADJ TOOL OPTION 2

This is very precious information. so this TV portion of parameters in memory are corrupted?

:-) That's what I thought / suggested earlier. Lots of posts with sets that have panel versus capability settings wrong as the company has various "production differences"... glad you found the right combination for the panel that you have.

Re: 47ls4500 screen has rainbow color.

first i took pictures of the service menu then changed each parameter until I found the correct combination, trial and error, it's kinda stupid but very effective method only took me less than 10 minutes.
