Tcl #l32b2500
I am servicing a TCL L32B2500 with no screen light.When I press the remote
to switch on the television there is a dim flash of light on the screen and there is no picture. When I look to the back of the tv there is no led light.I do not have a service manual for this tv but the voltage on the cable which goes to the
LED backlights is 45v and I do not know if this is correct.... -
