I’ve a Sony TV set KV-29LS60B that has an erratic behaviour.
It is the French model, board AE6B v 1.15 (Jun 2001) factory data DA 08 MSP 3411G.
It generally starts normally when it has been resting some time. Then after a time lapse that can range from a few seconds to a few hours, it fails and displays a three times blink.
When pushing then the TV 1/0 button of the remote controller, either it instantly restarts to work normally for a quite variable time, or stays in error with the three times blink. Other pushes to the TV 1/0 button may lead to the same three times blink, or some times alternatively to a two then three times blink.
The error menu not surprisingly says error type 2 and 3.
There is no T603 and R672 on this model, all components have a four digit code.
There is no visible sign of neither heating nor dry weldings.
There is only one MCZ3001D on the G (power supply) board.
Has somebody an idea of where I should look, is it worth trying to change the MCZ3001D?
