Hey guys. So I'm looking for opinions from experienced users on what to replace on my TV from the symptons it's having.
Here's my issue. Last week it was on Netflix, then when I changed the input from netflix to a hdmi source the screen flickered and the hdmi source image was dim and flickering on and off and the TV shut off.
When I turned the TV on I had no image, no sound, and no backlight. I waited like an hour and when I turned the TV back on the LG logo appears and I have back light but no image. I left the TV on just staring at it and the screen flickered and went back to the hdmi image for like 10 seconds then the image was gone.
So my tv sympton's are no sound no image but I do have back light at times. At times I mean if the TV turns on and there's no backlight I'll shut it off and wait a bit and then turn it on and the backlight comes on.
I took the panel off the back of the TV and exposed all the boards. I hear a slight humming from the t con board. If I take off a ribbon from the main board going into the t con the humming stops, when I plug it back in humming starts.
I'm thinking the main board could be the issue. I did have 2 blackouts last week due to a storm so I'm assuming the TV power surged...
I have a meter but I'm not familiar with testing boards.
Should I go ahead and get a the main board repaired?
Thanks in advanced.
