Backlight burned out and power supply went into protection by hitting the relay | At the power supply, ic9101, qq853, q9801 and rs802 were changed | Ic9101 caused the board to go into protection and transistors qq853 and q9801 did not conduct. RS802 is a common problem with this TV, but in my case I had to replace more components | rikadapper |
