Do you mean that it is cycling through its primary red/blue /green colors and perhaps black&white then repeats ?

This is a main board problem namely the eeprom chip on it and it has gone beyond reach of any control I`m afraid

Do you have an extended warranty by any chance ?

Customer reply replied 10 months ago
I dont know so ill have to check , so no remote buttons to reset it?. If not it is easy to do to just buy a new mother board and put it in?
TV Technician: Jack, Technician replied 10 months ago

The main board will need to be replaced or that eeprom itself but this is not exactly what I would call a DIY project

If you can pull out the back cover then you would have most of the work done though

TV Technician: Jack, Technician replied 10 months ago

Either you separately bought an extended warranty or NOT , do you know ??

what is the eeprom
Customer reply replied 10 months ago
What would the correct eeprom chip be for this tv
TV Technician: Jack, Technician replied 10 months ago

Its a surface mount chip and unless you are the proud owner of a tv repair shop then well beyond a DIY repair

Customer reply replied 10 months ago
i need to find original receipt to see if I purchased extended warranty. If not is it easier to replace the whole mother board that the eeprom itself
TV Technician: Jack, Technician replied 10 months ago

for you l, the main board that's for sure

can you answer the questions
TV Technician: Shahid, Technician replied 10 months ago

Do you see service code written along with the mode number of TV, it could be like BUSWLJR or some thing similar?

Or complete number would look like LG 75uh6550-UB BUSWLJR etc

Yes, thats what I'm trying here, did you get my previous reply?

Customer reply replied 10 months ago
if this is on the TV , its mounted on the wall and on the back
TV Technician: Shahid, Technician replied 10 months ago

OK, TV would have to dismount to remove back cover for main board replacement so you can check it at that time and check with following suppliers to get identical replacement main board to get it replaced in TV..

Cant i just take the main board out and put it into the oven for 10 minutes. It worked for a friend of mine?
TV Technician: Shahid, Technician replied 10 months ago

Sure, try it as it has nothing to lose because new main board option is always there so go ahead and try oven trick to see if it works for you.
