TV flash

After replacing every circuit board in this TV at least twice and seeing it doing the same thing every time with absolutely no change, the only conclusion is to change the LED strips. It fools you into thinking the strips are good since they do come on. However, there are websites that conclude a single LED could be burned in such a way as to still allow power to go through then trigger a shut-off in the power supply for the LED circuit. In this case, a Roku will still send a voice you can hear (if you have reset it). And, it will continue to try to power that circuit. The continuous flash indicates it is still trying to send power. The LED strips is the only logical conclusion. Unfortunately, my customer has backed away from this process due to my $100 fee plus the 50/50 chance of breaking the screen in the process.
