Sounds very much like a main power supply that needs a 'kick' to start up. This is often caused by the loss of value of a capacitor in the power supply, one that handles feedback to start the supply initially and carries the signal to shut it down in case of a circuit fault in one of the areas the supply services. Inadequate feedback will make the supply unable to start properly and more likely to shut down even though no fault condition exists. If I'm right, it will get worse and searching for the problem requires an instrument not found in the average home; a capacitance meter with loss measuring capabilities.

Media receiver "on" button flashes 8 times and turns the Pioneer TV to standby.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

Cant switch on my Irion TV


Maybe things will improve if you leave your TV permanently receiving power from the wall switch and do the actual on-off switching at the TV. Your Orion TV draws standby power even when it is off. When you flip the wall switch off there is no standby power

I have a 36'olevia HDTV.......it has a detachable power cord and it also has a power switch in back. When I plugged it into the wall,turned on the power switch, and pressed the power button, I got no


The light is likely the standby light if it is on when set is off and goes out when set turned on or changes color when set comes on.

The fact the light is on should rule OUT the main fuse for the set, most likely the problem is the power supply itself inside the set

The Standby supply is part of the main power supply and when set is plugged in and off it runs 7/24.

Have you had problems where the set was "hard to turn on" or you had to try to turn it on several times before it would stay on?

Hello, I have a Toshiba tv - model 42XV503D which has suddenly just switched itself off and no matter what I try it will not turn back on (upluging etc). The TV is around 3 years old. If I press the power...


Hi, Check solder mounts on power switch for dry-joints, (bad solders). If none are found I would recommend replacing the switch. The contacts inside the switch will be burned out but may be loosly connected when in the ON position when you are powering up from the mains socket switch. After initial power-up, (red light, relay click) the television will draw a huge amount of current to start up which the damaged switch will not be able to handle and will open-circuit.

Bypass the switch (Not Recommended unless you are familiar with electronics) You could try this to establish that the switch is the cause

Hope this is of help to you.

I must reprogram my tv each time I turn it on


I'm assuming that you are powering the TV off with the remote, not by shutting off a device (such as a home theater system that it is plugged into) and having it disconnect the power from the cord. if this is how it is shut off, that will be your problem.

Likewise, you may have plugged the TV into an outlet that is operated by a wall switch. These are typically found in rooms that do not have an overhead light, and are designed to control a table lamp. Usually, the receptacle will have one outlet that is on all the time, and the other controlled by a wall switch. Check to make sure that the outlet that the TV is plugged into remains on all the time - regardless of the position of any wall switches.

The solution to both of the above issues is to plug the TV into an outlet that is on all the time. The interruption of household power to the TV is most likely causing the memory loss of the settings in the TV.

The other possibility may be the way you are shutting off the TV each night. Some TVs have an on / off function that works with the remote, but only if the standby power is on. If the standby power is off, the remote will not be able turn the TV on. Some manufacturers use different colored indicating lamps for Off, Standby On and TV On.

Without knowing your brand and model TV, I can't go deeper than that. You'll need to consult your TV manual to see if and how your TV works - or provide the brand and model info so we can see if we can find a solution if none of the above works for you. I hope this helps & good luck.

When i switch my tv on it turn's itself to standby, i can switch it back on again but it just keep's switching itself to stanby after a couple of minutes.


You need a live input source to the port that the TV is set to, or turn on the tv and switch input to a live input source, anything else and the tv shifts to standby.

Tv will not turn on


I can only suggest one solution not a fix but will work without much cost. Try a wireless outlet switch... the switch I have uses a wireless frequency much like a remote control only an on/off switch... I placed the switch on my wall and plugged in the receiver into a wall outlet, then plugged in my table lamp to the receiver. Now I just walk to the wall switch and click it and on goes the lamp without me having to physically reach under the lamp to turn it on... wish I was more help but for about 25.00 dollars (think it was 14.00 at lowes) its a working solution...
