This TV turned on with backlight but no video. Normally in this scenario, the tcon board is suspect. I disconnected the ribbon cables from the tcon to the panel one side at a time and got a good picture on the right side. This test indicates there is a panel fault on the left side. I checked the panel board on the left side for shorts on the chip capacitors but didn’t find any. I next used the the tape cutoff method to block pins on the ribbon of the left side connector on the leftmost side (outer edge). The initial attempt blocking 2-3 pins didn’t work so I used a wider strip. With 5-6 pins blocked, the TV turned on.
