That's not how a tech works. They want the set on the bench where the tests and measurements happen.
Back to that tech and tell them it didn't fix it.
I have a 65UB9200 4K TV. When I turned on the tv with the remote, the center LG light comes on bright then quickly fades away with nothing on tv coming on.
I got on answer.com and a tech said probably is the power board. So I ordered and replaced the power board and same exact problem still there.
With the back panel off, I see a red led light on power board blink five times over and over. Is that an indication code of what's wrong?
There is only three boards on back, I replaced power board, only two left ... lol.
Anyone know what I should do next? Don't want to hire a tech and pay $600 repair for a $900 tv.
