TV will not turn on

My TV was turn on. I left the room for about 30 minutes and found my screen was blank with a clicking noise. The remote not the power button on the TV will make the TV come back on. There is just a constant clicking noise and the power light that is red is contanting clicking on and off. I should add that this TV is connected to DirectTV. I have try plugging the power into a another outlet and it doesn't help. Do I need a repair man to look it. I had to unplug the TV to get the clicking noise to stop.

    The TV power button nor the remote will turn the TV back on. And the clicking sound with a red light flashing, I had to unplug the TV.

If The other tech really knew about Zenith TV sets, he would know about the problem at hand. Your problem sir, is a bad capacitor in the main standby power supply or a short in one of in one of the many circuits of this TV. This could also be a bad horizontal output transistor. This is what would causes this set to turn off and on in a rapid sequence a lot of times. If you have no solid state repair knowledge, play it safe! Call in an authorized repair center to assist you in this repair. Good Luck.

Hi, If the clicking noise is metallic, could be a relay switching on/off. What's curious is that once powered on by remote, apparently the clicking doesn't affect the TV, meaning it continuously work. The relay is suppose to turn on or off a function of the TV and apparently it is trying to but there is not such effect since the TV, as I understand from your post, works. The relay can be for the degaussing coil, power supply, over voltage protection. Since this involve a little diagnosis of the electronics, soldering and probably a minor component replacement, an on-site service/repair man would be your best bet. Even if it were a nuisance/minor repair, you can at least get the clicking noise out. Other than you get to get a checkup of the TV and diagnosis of what caused/started the clicking sound in the first place. Hope this be of help/idea. Post back how things are or should you need further information. Good luck and kind regards.

    Understand now that neither the remote nor the front panel switch will turn on the TV.

    The blinking red light is a fault indicator. The clicking is the poweron relay trying to turn on your TV but due to the fault, the protection circuitry is auto switching it off and the cycle continues.

    In some models/versions this can be as simple as a vertical IC going bad or cold solder.

    Again an on-site tech would be in a better position for a full diagnosis.

Turn on the TV, red light stays on, picture goes blank after a second.


I have the same problem. Factory reset did not help (hold Vol-minus on set and menu on remote five seconds, then unplug). Can there be something in service mode that would help?

Created a 300 picture slide show on my pc. the screen will go blank after 30 minutes and i have to hit the return key or touch the pad. Is this a sleep setting issue or kodak?


I suspect you have a screen saver set up that blanks the computer screen after 30 minutes.
If you are running Window XP, right-click your mouse on the desktop, choose Properties, from the Display Properties dialog, click the Screen Saver tab, then in the Wait box, increase the amount of time before the screen saver activates. Click the OK button when you are through.
Good luck,

My Magnavox plasma screen tv, model number: 42MF237S/37 makes a clicking sound when I try to turn it on. No sounds, no picture, just the clicking noise. Things I have tried so far: 1) Turning the TV off...


You either have a cold solder joint in your horizontal deflection circuits or your or in your horizontal output circuit. please be careful due to the fly-back transformer still holds power even unplugged until you discharge it.( ground it out). Hope this helps.

61a60 Toshiba Flyback


Have you check the HOT Q404?
I would suggest to check that transistor before you decide to replace the flyback. The way to know if you are getting high voltage would be to pay attention for like a charging/discharging static noise when you press the power button to turn the TV ON or OFF.

Let me know if you require further assistance.
