(2) 55" TV's (Big Timber & Randall Rd, Elgin)

I have 2 55" TV's that we were going to try to fix ourselves, but our hands are kind of crippled & we dont have the area to open them up with. The older one is a 55" LG model# 55LA6900. The screen flickers like it has shadows , no remote & no power cord, but the power cord is a standard cord. You can still get the remote & cord on the internet. Then the 2nd TV is an RCA 55" ultra smart TV,model# RQSM5522, this one we only had 18 months; fairly new still. The back lighting went out on this one. Our warranty company replaced the TV for us saying that, that is not a big enough problem for a service company to come out ad fix it. I looked on line, & Utube had someone repairing the back ligts, he said it only cost him approx $35 for the lights, but he needed a BIG area in the house to open his TV up. He showed us once the TV was opened it was easy to replace. I was told that with this model the back lights go out a lot. If you are interested in trying to fix these; please take both TV's thank you
