SOURCE: Sharp LC-52D62U HDTV won't tune-in channel 21.

I finally got Sharp to repair the TV. It was under warenty but they said if the problem wasn't with the TV they were going to charge me for the service call. I told them I wanted a new TV. They sent the tech instead of a new TV. He replaced the turner card and it worked!! Now I get all the channels as well as channel 21.

SOURCE: No Signal through on my main TV input.

This may be the tuner or IF module that is failing. It may also be a voltage supply fault to these modules. It is impossible to accurately speculate without actualy troubleshooting the set.

SOURCE: input problem

If you have the original remote, hit video, source, or input button, if it dont have them, then try to change the tv to channel 00 (zero or zerozero), if not then the channels might have to scroll to it, from channel 02 down to make it loop, if it goes to the next highest channel, then you need a remote. It may be set in the menu options to have the video source not saved to your list of saved channels. when you scan the channels, the tv might not look for the A/V source (audio / video), maybe just the RF source. The 3 DVD RCA wires are 1 video and 2 stereo, one stereo for left and one stereo for right. The TV has only 2 , 1 for video and 1 for mono 1 channel sound. This wouldnt have anything to do with why you cant use the DVD player. but try that with the original remote (or a universal remote that is set to your tv set that has either video, input, source or something similar. It is what tells the tv to change from the cable source (RF) and the AV source (the Red White and Yellow plugs, in your TV's case, 2 plugs, one yellow and the other either red or white or something). Dont really know how to explain it much more but hope it helps.

What should i do for no signal tv?cables are ok,,,


Just do an auto-search function after connecting the external ariel, and selecting the input to TV. The set will start auto-search for all the channels transmitting at that time, and will show the first program that it got, after the auto-search is finished.
During this search time, the set won't respond to any external commands, including the it panel buttons. Wait till the auto-search is over. It might take about 3 to 4 minutes.
There is nothing more to do. Refer its user manual for more details about how to do an auto-search function.
If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

Lost BBC1 BBC2 digital after switchover


You might have more than one transmitter. Some TV's etc only store a certain number of channels and have a max amount!. When weaker transmitters are present sometimes the memory of the TV will only store the stronger signals first from these weaker sites, with the two BBC channels being too weak to be detected.
The solution is to do a manual search on the transmitters you know are very strong. For example if channel 43 has strong signal you would search on that. The auto search will start at 21 and work it's way to 69. But if your area transmitter with the strongest signals is high up the scale the weaker transmitters will be selected first!

I connect the cable,it doesnt show anything!I try the auto channel search for both cable and antenna,it doesnt find any channel at all!it says-no signal..-rca 20inch sdtv truflat.dual combo with dvd player...


I assume you tried the cable on a working TV to make sure there is a signal on the cable line and that the cable terminal is OK. See if you can control the input selector and set it up for RF or TV reception. If OK, try to tune in channels manually or in auto mode. Do this in programming mode. If you notice any noise on the screen, this means the source selector circuit is OK. If there is no noise, the source selector may not be latched to the RF circuit output. Try to feel the terminal at the back of the TV set. If it feels like it moves when pressure is applied in various directions, chances are the solder connection for the terminal onto the circuit board may be faulty. Resoldering them would be easy for DIY enthusiasts. If it isn't the culprit, try the DVD. If it works fine, then the video circuits must be ok. The trouble could be from the video source selector circuit backwards to the RF block. Usually an IC senses the power condition of the DVD player. If it senses that the player is ON, the IC latches on the signal coming from the DVD player. See if there i a separate power button for the DVD. More later, please post a feedback

PANASONIC PV4022


One way is to manually select the missing channel with the numeric keypad, then push "add." There is also an auto program function puts the VCR into a search mode, adding all channels where a good signal is found. Early VCRs (like late '80s or so) did not have this auto mode, but many later ones did. Also, make sure your VCR is set to the "cable" or "CATV" mode not "off-air" Do you have the VCR manual? If not, recheck your model and see if Panasonic has it online at http://service.us.panasonic.com/OperMan/Default. aspx I looked at at a manual for a PV-4651, and it showed functions which sounded similiar to what you need. Check pg. 10-12
