Question about Toshiba Televison & Video

1 Answer

Just experienced a problem on tuning two t.v.'s in separate houses. Neither picked up STV, channel 4 or 5. These were both o.k. yesterday. One signal is from a digital loft aerial, the other from set top digital aerial.

Aerial signal was the problem.
New aerial required for one and new lead required for other.
Coincidence that both occurred at same time.

How to tune a tv channel


This could be too much signal.

Just to be sure though, try the set in another room where one of the other TVs works okay. This will help you see if it's a cable or a TV signal issue. If you pick up all the channels okay it's likely that that other TV point has some bigger signal losses due to the cabling.

The mux (transmitter channel) carrying the BBC signals will be amongst the strongest at each and every TV transmitter across the land. This is because the BBC and the main ITV channels have to reach about 96% of the mainland UK population in order to the broadcasters to fulfill their remit.

TV tuner sensitivity varies between brands and models. It may be that your old TV was just about okay with the signal power, but the new TV's tuner is over saturated.

A simple and inexpensive diagnosis tool is a variable attenuator. The MA1620 on this page is perfect for that job:
Splitters amplified splitters and attenuators

It will give you a way to reduce the signal level at one TV without affecting the other TVs in the house.

I cant get any BBC programs


Check and replace the tuner to this set. It is weak. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box and press "Enter".

LG M227WDP tuning problems


Hello
sounds like the memory IC to the TV has damaged. It is an IC, which stores all the cunsumer adjusted data, as digital signals, and retrives thme to the main system control IC, each time the set is switched ON.
It is an 8 solder terminal one, a small IC. Even though, its size is small, function of this part is very crtical, when the set works. This IC can be located very near to the main system control IC, and can be bought from most of the electronic spare part selling shops at your town.
The only thing you need is, to locate this component on main baord, and desolder it out, and resolder a new one in place. Somewhat skilled work indeed.

Yes its antenna problem?maybe your house too closed signal your antenna is getting hard to find signal for your TV.

You must use a Outdoor Antenna to widen your signal range.

And also i suggest that you move you antenna outside your house or at your roof to be able to enhance the signal for your TV.

Hope my solution will help.

When you are auto tuning the system will not store a channel which is week by its standard ( at least 60% signal strength ) This done to avoid grainy picture and hissy sound.
You can go into manual tuning and store it.

Just purchsed the tv yesterday at Best Buy. Some


Some of these new LCD and Plasma sets are very picky about the signal---I am in a room where I experienced the same problem--the OLD tube set had a perfect picture but the LCD had grainy and noisy pictures on some channels.

Before you assume it is a problem with the set (unlikely) contact your cable provider and have them come out---if the physical cable into the house is old they may have to replace it or do something else.

Let me know if you have questions--I am here to help.

Tuner Problems


OK the tuner may be causing these problems, however first I would like you to go to your menu and set the RF pickup to antenna (This will allow analog channels) then come out of the memu and select a channel in the analog range channel 4, 7, or 9 try to tune in these channels. If this fails then you may have tuner problems the only way to be sure is to use a RF signal generator to send RF through the tuner and see if the video and audio being carried on that signal comes through. Sometimes the Internet connect gets messed up when the TV does not have the proper RF filters this may be your case. Try this use a Cable tv set top box and just set your TV to channel 3 for cable. This should Isolate the TV from the Internet cable modem and provide the signal needed by the TV.
