My TV generates a noisy picture and audio noise, both of which vary in intensity. They could even go off for a few seconds. The noisy picture and audio noise are appear at the same time. Especially the white lettering seems very choppy. I brought in another TV and plugged the TV signal cable from my noisy tv to this other. The other TV had no noise. So its definitely my TV.

If the fan is very dusty that an cause a lot of noise as it will be unbalanced. If the fan is on all of the time, maybe the bios requires updating. There may be a GPU issue and that will make the cpu run hot.
Yes...this TV may be repaired. The line you describe is in the center and is horizontal across the TV. You will need to resolder the vertical IC pins. This vertical IC is mounted on a large heatsink. Under the board you will see there are 5 or 7 pins that will have rings around them. Resolder these. And you should replace two or three capacitors that are next to this IC. A bad cap will overheat an IC and separate the solder grounds. If you can find my expertise page on this website, you will see the repair in more detail. Thanks for asking and show a few hands of support.
Disconnect your TV. for few minutes (10) then plug it back on, turn it on using your remote control, wait few seconds, until the light bulb gets its normal intensity, if you can not see anything, but there was a clicking noise,then you bulb it's burn out
Some el.components are loose on tv circuit board.I have removed the back cover,supported tv picture tube 45 deg.against wall.This tv is heavy!One screw on left holds the circuit board to bottom case.Removed and supported this board on few heavy books.Turned tv on and gently probed all the componets on top of the board with plastic drinking straw.In my case transistors Q-830 and Q-421 needed resolder loose joints.These components are mounted on flat aluminium heat sink strips located sligtly left of center of the circuit board.Also blobed bit of silicone into base hole and foot of alu.heat sink to support it.
I should mention, however, that if it's connected to cable (or certain satellite services), you won't need a converter to watch the TV - you'll receive the digital signal (although you won't have the 1080-pixel HD resolution - the 36A50 only has 850 lines of resolution).
I hope this helps. Please let me know if I can be of any further assistance. H2H
