Hello everyone, any advice and opinions are much appreciated. Im going to try and give a lot of information so that maybe someone will just know for sure no question what the issue is!
So I got a Haier (junk brand dont ever buy from them) LE46F2280 as a warranty replacement for another that died after 6 months. This one lasted only about a year but its out of warranty now. Heres what I know:
I plugged TV into a pure sine wave UPS and around that time it started making a buzzing sound for about 2 minutes whenever first powered on. The pure sine wave should be better for it than regular so maybe that part is a coincidence not sure. The TV was on and I needed to change a light switch I just left it on and let the UPS keep it running. After I swtiched the circuit breaker back on the TV was still on but picture is messed up. I did some research that strongly suggested that the t-con board was the issue so I swapped with one from ebay but it had no effect. By the way it is now plugged into a regular outlet. The backlight appears to be fine but you can see the vertical lines and half the screen is black. After being on about 30 seconds the half that was on goes black as well. The pictures are when first turned on and after 30 seconds.
So does anyone know or have strong opinions about what is bad? As I understand I can replace the power supply board and mainboard but not the "panel itself". Thanks for all help!

. But in the meantime I have 4 Capacitors that need immediate replacing each rated at 16V 3300uf and 105deg. I saw a break down review You Tube video where the host suggested that the 35V Capacitors were a better choice for manufacturers to use. Another video suggested that replacing capacitors of higher Voltage is fine but that the 3300uf rating should be kept the same. Can someone please clarify what the functional benefits...
