My Expertise has been in: Video, Audio, RF, Television, and Stereo. I have been in the Television repair business for 25 years and have repaired over 20,000 Televisions in that time. I was a manager of an Information Technology Training Team at The Verizon Advanced Services Group Center, and a Distinguished Member of Technical Staff at Verizon Laboratories. I am now working full time in the TV repair industry until I can find another full time job, I know what your question is: "why don't you just work full time in the TV repair industry permanently?" Well the answer to that is simple, due to the complexity and the DIY craze, TV repair work is at best a good way to make extra money, not to rely on it for your livelihood. A sad truth, but a truth nonetheless.
Experience 25 years as an Electronics Repair Technician, 20 years as a Telecommunications Expert, and I love Electronics.

Question We have 32 inch AC HDTV, when we try and turn it on it makes an intermittent high pitch noise and then the whistling stops and the standby light starts blinking.
Answer Hello Emma,
This sounds like a problem with the inverter or the Ballast that provides energy for the firing of the backlight for an LCD screen. The ballast is a transformer that supplies high voltage for the backlight element. The TV is shutting down to avoid damage to other components because of a high current event. I would suggest that you have this TV examined by a qualified TV technician because of the section of the TV that is having the problem contains high voltages and current and could pose a danger to you.
The areas the technician will check are:
The Inverter Board
The Ballast Transformer
The switching power supply transformer
