Tv dead. high-pitched whine when plugged-in.

I was watching the tv. I heard a click (relay?), tv was dead. There was now a high-pitched whine coming from the inside of the tv that wasn't there before. I hear it when tv is plugged-in. I changed the power supply board but made no difference.

Sounds like the back-light inverter board has damaged. Check it.

    I'm sure you're right. Everything I've found online agrees with you. I didn't know this TV had a seperate inverter board until I found out it's hidden inside the LCD unit. THANKS!!!

This tv is under five years old?Yes,it is worth fixing.Over five,i would compare the prices for a new LCD tv and the quote priced from the Tv Tech.for the old tv.This tv have high voltage problems around the Deflection circuitries area.Could be any things burn in this area.The high pitched whine sound,i'm sure it is from the FBT-the high voltages flyback transformer,high voltages current have no where to go.Must hire a tv tech. to troubleshoots and replace parts on the Deflection circuitries area.Also the FBT could be dead too,because HV Current bounces back forth and have no where else to go.The prices to troubleshoot unknown problems is about $400 bucks and plus cost of replacement of parts.

High pitched whine/sometimes TV won't turn on


The power supply on this model will whine when it is shorted or overloaded - the set would have to be brought in to determine exact cause.

High pitch sound coming from circuit board, cannot


First, you will want to isolate the problem. Is it feedback from an AC outlet you have it plugged into? Is it a recent noise that just started with no changes to Tv or its environment, then you may want to consider that a circuit is going and decide if it is worth repairing, You should find that type of fix at a shop for under $100

Will not power up


your problem is in flyback or high voltage section failure.

  • check horizontal output transistor
  • check fly back transformer.
  • check for supply to horizontal section as high voltage from power supply may create such problem
  • as this failure is due high voltage section so it is better to take skilled technician help.
  • good luck.
