Hi there. There is a KDL43W808C
Initially, the image on the screen began to disappear randomly, after a while, sometimes immediately.
The TV at the same time reacted to the remote control, played the sound. The LED backlight worked properly at the same time.
I was sentenced to replace the t-con board (T550HVN08.2 BD CTRL 55T23-C03). A new one was ordered at a well-known Chinese site.
The parcel arrived in 20+ days. I replaced the t-con board. The TV turned on completely immediately without updating firmware.
After switching off and falling asleep, it was turned on again. After 10 seconds, the TV went into emergency mode (5 flashing red, pause, 5 flashing red, etc.).
Performed a hard reset with the buttons on the back of the TV.
I updated firmware the TV successfully via USB flash drive to v5.457 (prev. v5.433). I thought that the problem was solved.
But the situation with the emergency mode was repeated if you turn off the TV for a long time (when you turn on after the inscription "Sony" and the balls of the screensaver "android" (after 5-10 seconds) again 5 blinks red.
If you make a hard reset again, then the TV will work for as long as you want before switching off and falling asleep.
Accordingly, self-diagnostics entered me from the remote control and we see such a situation. It turns out that the t-con is defective?
Interestingly, there was never an emergency mode with flashing red with the old t-con board.
Thank you in advance for your help
