Question about Sony BRAVIA KDL-V40XBR1 Television
I have replaced the Power Board to repair what I thought was the problem, the unit when plugged in turns on power/standby light but continues to cycle on and off during the warm up phase and makes a loud click and shuts back off. Screen and fans will activate briefly but seem to also cause the power to cycle off. Entire process lasts 5 sec then starts over?
The lamp may be faulty needs replacement, another culprit is the color wheel when worn out they tend to get stuck and cant spin hence the clicks as tries to spin needs replacement most color wheels come inbuilt in the light engine u will need a tech to replace it and u are good to go remeber the lamp cant turn on if the color wheel is stuck cos its the one that syncrinizes with dmd board which in turn activates the ballast board to fire or light the lamp
