Re: no power when power button is pressed

I would have to say you have a dead power supply. You will want to make sure first that the "MAIN" power switch located on the lower left on the rear of the unit is turned on as well. Without that on there will be NO standby light.

My JVC model. my JVC TV LT 42 EM 59 will not come on .I get no blinking blue light no power no nothing I get nothing I've tried to reset it in nothing

With no power it will not reset---if total dead unit you would have to first follow the power cord into the set to the line fuse it goes almost directly to---check the fuse first and examine the power supply board for damage or puffed up filter caps.

Toshiba tv 40rv525u has started to change channels

My TV 40RV525U changing channels, menus itself for few months ( I use antenna).
my son tried to stop the channel scrolling by enter weird number into the channel to stop it scrolling such as 555, 777..
later, it turn on off by itself and unable to hold on a channel
I call Toshiba customer service and they ask money $25 for troubleshooting but I denied since I do not want to waste money and time.

Now, I found how to fix it myself.

In my case, something was wrong with the signal comes from the button control on the left side of the TV.
What I did
unplug the power cord.
Remove back cover.
Look into the motherboard ( biggest green at the center).

First, I disconnect a connector on the motherboard come from the IR board that receive the wireless signal control ( meaning the remote is disable).
I turn on the TV, press on Menu button on the TV side. Menu is still scrolling.

I turn off TV, disconnect power cord and connect the IR connector back to the motherboard.
I then disconnect the nearby connector that comes from the side control buttons.

Turn on the TV by remote, press menu button on the remote to check. The menu stays.


I use electric tape to seal off the connector and let it hanging there.
Close the TV back panel

I have been watching TV for 3 nights without menus/channels scrolling.
NO AVAILABLE red message when watching DVD is no longer existed.

Hope this help someone else.

My tv won't turn on anymore. The power light and the opc light blink twice at the same time and then the opc blinks once and it keeps doing that. Please help!


Make sure the AC cord is not loose or disconnected. Check to ensure the cord is firmly plugged into the outlet at one end, and firmly connected to your television at the other end. The AC cord connects to the television about midway across the back of the set, near the bottom of the back panel. The hole for the AC connection is shaped like a figure eight. Try powering up the TV with the cords firmly connected.

Check the "Main Power" to ensure it is on. Locate the button on the top of the television among the "Volume" and "Channel" buttons. Press the button to switch the television on. If the "Main Power" button is off the remote will not turn on the television. Wait to see if pressing "Main Power" will activate the TV.

Press "TV Power" on the remote control to power up the TV from stand-by mode. If the power light on the front of the television glows red when you press "TV Power" on the remote, press the "Main Power" button on top of the television to remove the TV from stand-by. If the TV is accidentally in stand-by mode it may not come on when pressing certain buttons.

Check the circuit board. If your set still won't turn on and you hear a clicking noise when you plug it in, you most likely have a defective circuit board.
