No signal The initial screen says No Signal and when I try to change channel the channel number displays 65535 followed by a line of yyyyy where you would normally see the program. The TV worked last night and this morning was turned on by a teenager - I am not sure if he has accidentally pushed a wrong button.

Try first if you have not to remove set and any cable or sat box from power, a box etc can cause this--when you plug back the units will try to reboot, cannot hurt and may help.

It sounds like the TV has re-mapped the channels incorrectly. You possibly can contact Toshiba to see if there is a firmware/software upgrade that will fix this issue. If there is you may be able to download the software off of their website and install yourself. Just make sure if that is the case follow the directions carefully. Please take a few moments to rate my answer. Thanks..

Sections of the power supply may have gone out, or it detects short circuits in the backlight inverter board or in the power supply itself.
Those are the two areas you need to check. Look fo bad caps with leaking/bulging top fist in the power supply.

SOURCE: no video signal shows up when i turn on tv. i hear

First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

SOURCE: My Toshiba flat screen is not picking up the local digital channels

As an past Radio Engineer I feel compelled to tell you that the conversion to HD in FM and TV signals did not do all of us a favor.
The coverage pattern of stations has decreased to the level of about 70% due to this new advanced technology. I think what your real problem is comes from a misunderstanding of what a HD TV signal must be supplied from. In my house as an example which is 21 mikes away from Chicago and the Willis building where a lot of TV signals are from, the need to put up a new higher gain $100 HD TV antenna was required. You can get such antennas from Antennadirect web site. You will also require a length of high grade 75 ohm coax cable- I bought the high grade Digital TV cable from Gepco International with a 3 GHz bandwidth and also distribute the signal to a number of TV's either with a Wineguard or Blonder-****** distribution amplifier.
My antenna is mounted near 30 feet off the ground. Places like Radio Shack may sell these kinds of indoor TV antennas but they are depending on the lack of knowledge of the people buying them to sell the product. It also depends on how far you are from the source of transmission. If you are 5 miles in a high rise building facing the transmission tower, you might have luck with an indoor antenna, if you are 20 or 30 miles away from transmission you might have to go to more elaborate measures to get a signal down to the TV. There is no magic to it just a need for a person who understands the signal levels and what is needed. I spent time as a Chief Engineer for 4 Radio stations in Chicago as well as was involved in a FM HD installation or two.
See if you can find a Television shop that you can ask questions about your installation. They may be able to help you mount a roof antenna if you can not do it yourself.

CANNOT GET itv1. NEED TO RETUNE BUT DOESN'T PICK


Good Day,

Try this to reset your programming, but try to reset the whole set by unplugging TV and BOX from power source for 3-5 minutes then plug power cord back into power source. If that does not work try this:

Option Menu Setup
Follow the steps below for the initial set-up:
1. Select the "MENU" display by pressing the "MENU" button once.
2. Press the number buttons "0", "1", "7", "0" in sequence to select
the "OPTION MENU" display.
3. Press the "ADJUST" button to select "INITIAL."
4. Press "ENTER."
NOTE: At this time channel 3 is automatically selected.

My Zenith C32V28 television does not display the top and bottom of the picture. I phoned Zenith tech support who told me that it was the satellite signal. I called the satellite provider who advised me it...


This is applicable to Bell Television Services (Canada)
I solved the problem myself after two calls to both Zenith and Bell Television satellite service. On the bottom left of the Bell remote control there is a * (STAR BUTTON). Press this * button and within two seconds you must press the channel change button up or down. This will do two things. One; it changes the channel; and also changes the ratio of the satellite signal. There are three satellite signal ratio settings. Try this when you are tuned to a TV channel such as BNN (Canada) (Business News) or The American channel which has a stock ticker usually displayed along the bottom of the TV screen. Select the ratio (setting) that allows the stock ticker to be displayed......hope this helps.........Jim McP

Can not tune the tv


My dear friend. A TV is a TV and TV's are many and varied. If you stated the model and what it exactly does, maybe I or other people could help you instantly. But since you have said little in relation to TV tuning, then expect a few guys to help you. But allow me to give you a hint that applies to almost all flat panel TV's, ok? Right. On every TV there is a MENU that gives you many options. First you need to press a button on the remote that displays component connection channels and TVincoming signal type. Since I don't know what brand of flat panel TV you have, I can only ask you to find and press the button on the remote that displays on TV screen the following component channels, that is DVT, AVT, Component 1, Component 2, HDTV1, HDTV 2, HDTV 3 and so on. Apart from DTV and ATV, from Component 1 to HDTV 3, these additional channels are for DVD players that also have HDTV outputs and BlueRay players and or Audio devices. If yout TV hasn't got as many channel input, then ignore this part. To tune your TV you have to first press the butoon on the remote to activate the onscreen channel as above, then scroll on DTV or ATV and, depending on whether you have Digital TV in your country or the standard high resolution Analog TV. Lets say you have Digital NTSC format TV system, select it and then press ENTER on your remote. In the menu you find and click SCAN. Depending on where you are, the TV will begin scanning all frequencies in your territory and possible interstates if the modulator is powerful enough to pick up weak signals. Most TV's have an inbuilt set-top box that boost the signal to give you a crystal clear pic. Now, after pressing SCAN, the TV reaches a signal with a clear pic, all you have to do is recognise the channel that comes in view. The instructions on how to save that channel are on screen and then you can configure it as, say channel 4, if the channel that appeared is channel 4, if not, try and recognise what channel had appeared and then configure it with a number, so when you press that number on the remote it will be the same channel you had stored in the TV memory. After you have done this, press scan again and it will scan to the next channel. Once the scanning recognises another clear signal and it is as clear as a baby's face, you have recognised the new channel. Try, find out what channel it is by looking at the screen, there is usually a visible TV station name or number embossed on the lower corner of the screen, once you know what station that is or what channel number it is, configure that number and press ENTER (save) button. Do the same with the remaining channels. Later I will tell you how to skip unwanted blank channels that usually have no signals but snow and lines, or have faint signals that can only be boosted with a TV booster available from reputable TV retailers, or install a bigger more powerful antenna.

Reagards.

I need to change the channel on my dlink 625 router..can u help?


I presume it's a cordless phone? If so, it's possible that it's interfering with the wireless signal. If that happens you will see the wireless connection being dropped - go into the wifi config utility and check how good the connection is. If this is the case, changing the channel may help. To do that,bring the router over to your PC and connect with an ethernet cable (just in case something goes wrong with the channel change and you lose the wireless signal.).

You need to find the "router homepage" in your web browser. If you don't know what it is, in windows click start -> run -> type "cmd" and press enter. In the command screen that pops up type "ipconfig" and press enter. It'll show you a few things. One should say "Default Gateway" followed by numbers.Write those numbers down (probably will be something like 192.168.1.254).

Open your web browser (IE, Firefox etc...) and enter the numbers. This will bring you to the router page. There should be an option like "Wireless" and under there you should see "change channel". It may be in the advanced option window.


IF your computer is NOT dropping the wireless signal when the phone rings, but the internet connection does drop - check the DSL signal light on your dlink. If it is flashing or not on, then the problem is with the DSL filters (small white connectors sent with your modem.). Always ensure any phone on the same line as the DSL is filtered or it will cause the internet connection to drop whenever the phone rings or is picked up.

Initial hdmi tv, no signal received


If you are trying to get 'off the air' signals then you must scan for the new digital channels in your reception area (this info should be in your owners manual). If scanning doesn't find any signals, you might have to add a VHF/UHF line amplifier(s) between your antenna and the TV set or improve your outside antenna or the cable leading from it to your set. You might have to resort to subscribing to HD cable or satellite TV.

Turn tv on and get no program or weak signal message.


You should be watching tv in no time. Email me and let me know how it went I would like to know if I was able to help. surfpro@yopmail.com

1-You didn't say what model tv you have. Is it a HDTV?
2-Are you using an over the air (roof) or set top antenna connected to the tv?
3-Are you getting the no program or weak signal message on all channels?
4-Have you tried first cycling through the source or input button to make sure you are on TV and not on an input. Sometimes if you are on an input and for example the device connected to that input is off you wil get a no signal until you turn the device first but you probably already know that.
5-When you were in the process of scanning for channels assuming you had an over the air antenna connected did you make sure and select the ota option and not cable? if you have an ota antenna and not cable you need to select ota before scanning for channels.

Now assuming you have an ota antenna and you chose ota before scanning or doing a re scan and after the scan you still get the no program or weak signal message that means there is no signal and you may be using the wrong antenna or try moving the antenna in the direction of the television tower if you know where that is or turn in another direction but unless you are using the wrong antena you should get something.

Assuming you received some channels or even if you did not, try to and add channels by hand. Heres how: first you need to know the RF frequency channel or digital channel its transmitting on you just cant input the number of the display channel you want like on a tube at least not initially but you can after you first input the rf or digital channel number first and saving it on your tv then you can just input the display channel number you are used to. Heres how to manually force the tv to enter a channel without a scan or re scan and possibly loosing other channels with a rescan.

Go here http://www.rabbitears.info/search.php and go to state search choose your state from drop down list and click search now do you see the list of stations? on the left you have the display channel (thats the number you usually entered on a regular tv) and next to that is the digital channel (thats the number you need to enter on an hdtv or dtv initially to force the tv to accept the channel because if you just enter the number your used to initially the tv wont find it) the tv should now automatically redirect you to the channel you are normally used to and any digital equivalent and any sub channels for that channel. Now save it into memory in your tv menu channel list. do this for every channel for your area if you were unable to pick up any stations during a scan.

No picture - 65535 shows on screen


My 42" Dynex just did the same thing. 65535 NO SIGNAL.
The channel label for this said "ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ"

I went to menu... Channels .... Set for Cable TV... Scan Channels.
It rescanned. It took twice as long as normal to scan.
After the scan completed it worked fine except of one thing.

ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ stuck on the screen.

I shut the TV off, then things returned to normal.

Hope this helps.

Notes:
This TV is only 6 weeks old.
Cable hook up.
It is -plugged into a brand new UPS power supply.
I used the sleep timer to shut off TV. The 65535 problem occured the next time the TV was powered up.
