Default Re: Philips 234e problem

You said if you disconnected the flat white cable between the t-con board and the main board and the buzzing noise stoped, Did the backlights come on? they should have. There are a lot of components on that t-con board so something could be bad, but there is a 2.5 amp fuse (F1) on that board, I would think if the fault was on that board the fuse would have blown. I suspect you have a problem with the +5 volts not being able to supply any current.
