    Our power went off later in the morning for about 20 minutes. Sould we still try solution 1?

    So if unplugging didn't work, a repairman is required, correct?

    Thanks for the assistance!

The clicking your hearing is the relay which is bridging to try to take the TV from stand by power to start up power supply when the power switch is closed. You can try unplugging the set to see if it resets, But i believe the problem will be in your power supply section of your set.

    Yes, I would however insure that the repairman is certified to work on your type of TV, as an inexperienced repair shop can cots extra money by replacing Boards that you dont need replaced.

    t The clicking sound it is caused by TV safety switch preventing TV from turning on. Internal safety Switch prevents tv from turning on when a short or an overvoltage is detected.
    This is often caused by a faulty IC, a burnt capacitor or another faulty component on tv board.
    Try first unplugging power cable for 5 minutes, to see if this reset TV, as sometimes safety switch is just stuck.
    If it does not clear the error, then the unit must be taken apart an the board tested with a multimeter until you find the problem.
    This job should be done by a technician, unless you have experience repairing TVs, I suggest to call service, you will find repair service phone number printed on last pages of your TV owner manual.

    Regards

    Even if power went off two days ago you should do unplugging if you havent done it yet, try first 5 or ten minutes, then 20 minutes if first attempt did not work, when power is drained from tv safety device wil reset, unless a component had been damaged during power cut, this will fix the problem.

    Yes, when unplugging does not work it usually means there is a short or a faulty component, to locate and repair the fault you need a repairman.

Why does plasma TV have no picture?


What brand and model # is the tv? This is very important as far as researching your problem. You probably aren't the first or the only person with this problem. There are typically four to 5 boards including an x main, a y main, power board and others. Sometimes easy stuff like capacitors or fet's go bad and you can fix it yourself pending your soldering abilities. Sometimes whole processors go bad or entire boards and these need to be replaced. Sometimes people want to fix sometimes they want brand new

My TV died & all that remains is the red light of death!


What you see is an indication of some failure inside the board. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

Red power light continuously blinking. no picture no sound.


It could be the lamp went out and needs replacement. The Toshiba website states when this happens to unplug the televison for 10 minutes then plug back in. If that does not work then try another power outlet. If that does not work then call for service
