I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.

SOURCE: Blinking yellow light ,no picture or sound.

You have done all you can do. If you had a power outage, when the power came back on a it surged and probably caused a Power Supply problem or something in the micro controller to fail. Either way it 's not good. I would call Toshiba and let them guide you to a Service Facility that can check it out. Depending on your Homeowners Insurance, repairs could be coverd or unit be replaced depending on cost to repair.

SOURCE: Can't change channel using the remote or buttons on tv

Simple Fix

I had the same problem, couldn't change the channels with the remote or on the side of the TV. This was for a Vizio 37"

Here is the fix:

1. Turn on TV

2. With remote, press the Menu Button

3. Go to Antenna Menu

4. Select Auto Search
Let it search, it could take several minutes. It may not finish to 100%, mine got stuck at 79% for 10 minutes. It's fine if that happens, go ahead and cancel.

5. It should be done, your remote will work perfect along with the TV channel buttons.

I had my router working fine then messed it up by my son screwing with the security password I have left it unplug and would like to get it going again.. How is this possible when it seems that nothing is...


Hi Megan,

On the back of the router there is a hole, probably marked 'reset'. Press and hold this button for 30 seconds and this should reset the router to factory settings. After doing this, unplug the power from the router and your modem. Plug in the modem first - wait one minute. Now plug in the router and hook everything up. Now you can set a new password on the router to prevent unauthorized access.

Please let me know if this doesn't work and I can help further.

Regards,

Joe

TV does not recieve a remote


Hey, Have you tried to power cycle your remote? That may work, do the TV too. I'll give ya the steps, just follow them and you should be ok. I'll throw in a factory reset as well, but if you're not using a cable box you will have to run another auto scan. anyways start off by unplugging the TV and removing the batteries from the remote control. Let them both sit, you don't have to let the remote sit really, but I do for good measure. You have to let the TV sit for a minimum of 5 minutes. at the end of 5 minutes, you have to find the physical power button on the TV, this means NOT on the remote, but on the TV itself, you have to find this power button, and you have to hold it down for 1 solid minute. Again, any time you can do something extra for good measure, it can't hurt, so if you want to leave it unplugged for 10 minutes and hold the button for 2, go for it, it may help. After you're done with that, power cycle the remote control. Being that your remote seems to be haywire, go ahead and press every single button, this means channel up and down, even if they're on the same button, every one from the top to the bottom, 5 times with no batteries in it. Then hold down the power button on the remote for 30 seconds. Then replace the batteries, preferrably with new ones. This completes the power cycles for both the Remote control and the TV. Now, before plugging the TV back in, we have to do the factory reset. Again, hold the power button on the actual TV, and then, while holding down the power button, plug in the power cord, wait for a couple of seconds, and then release the power button. Wait for a moment, and then turn the TV on. This completes the factory reset.

The reason for all of this, is, power cycle the remote to drain it's capacitors and reset it, power cycle the TV incase the Remote sensor is affected by a static electricity build up. Factory reset incase any settings may have caused this. Hope this helps.

Motorola SB4200 Modem IP not working


You can always do the 30-30-30 reset as follows:
  1. When router is powered on, press the reset button and hold for 30 seconds. (Use a paper clip or something sharp)
  2. While holding the reset button pressed, unplug the power of the router and hold the reset button for 30 seconds
  3. While still holding the reset button down, turn on the power to the unit again and hold for another 30 seconds.
This should allow for a full reset of the modem. Once that's done, connect your computer to it with an Ethernet cable to access it's WebUI using the Default Gateway (192.168.100.1), or connect to the WIFI using the default SSID and Password that are usually written on the modem itself.

I hope this works!

Hello all, I have issues with acer travelmate 2420 wifi driver! I have downloaded the driver from acer site but it still doesn't work, I have also tried to install it from the recovery cd but it still...


Hi there
You may have hit the WiFi activate button, it should be above the keyboard on the left hand side, if it still won't connect try resetting the modem by unplugging power from it for 30 seconds and power it on again, wait a minute for the modem to reset and try connect again

Good luck and kind regards

My 32" sharp lcd doesn't respond to the remote


Ok I just dealt with the Sharp customer support for this problem. 1) You need to unplug the TV for 1 full minute and remove the batteries from your remote aswell (this will reset the system)
2) Hold the power button on the remote for 30 seconds with the batteries still out of the remote and the TV still unplugged
3) After the 30 seconds replace batteries then press every button on the remote beginning with the power button in order from left to right and top to bottom (same way you read)
4) Then plug your tv back in and try the remote again.... and the remote and TV should be back in sync.

... let me tell you I thought the lady was crazy when she was telling me this but it worked!

You can try unplugging the power supply and phone lines for a few minutes. Then reattach the phone lines and power up to re-boot.
