Question about Sansui Televison & Video

1 Answer

During Channel scans or while loading a channel, the TV switches to stand-by for a few seconds. If this is during a channel scan, it stops scanning, returning to the last channel before scanning started. If this is while loading a channel, it will repeat the sequence for a number of times, before loading.

    I went to directly to Sansui website. There was nothing there for support. Do you know where I can go for the Firmware? And once I find it, how do I load it into the TV?

Sounds like a firmware bug.

Check the TV manufacturer's website for firmware updates of the TV.
By the sound of it, wouldn't be surprised if you find one that addresses this very problem.

It may as well be a cold solder raising resistance during some local power consumption / temperature peak due to whatever special is happening at the time of accuiring a new channel, e.g. signal bufferring or somethig like that.

In case or the later, the only solution would be a new tuner or main board, depending on where the problem is happening...in more recent TVs it is all on the same board, so that should be easy.

    Afrad not...if I had a TV like this in here for repair I would try to reset to factory defaults and if that doesn't help I'd be looking to replace main board.

I am rescanning digital channels after cable change. It tells me no channel is available and defaults to 1-0. I tried hitting enter on the remote nothing help!


Do you see any glimpse of any program during the channel scan. If no, check the cable input connection for any loose contact. If the connection is found OK, the tuner of the TV might be defective.
If you can see glimpses of programs during the channel scan, and no received channels are stored after the scan process has been completed, the main system control memory IC of the TV set is faulty, and should be replaced.
If you wish to get more details, visit the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

If there is no channels after scanning is it the outside antenna?


Do you see any channels [as a glimpse], during auto-tune. If you see them for a moment during channel auto scan, and do not store them in the TV memory, after the channel scan has been finished; the fault is with the TV itself. If you do not see that glimpse of programs during channel auto scan, there are two possibilities.
1. The tuner of the set is faulty.
2. The set do not get any signal to process [might be antenna].

Grecom psr-200 .when scanning weather chanel comes in .what is problim.


IF you have a weather frequency programmed in as a scanning channel, it will stop on it everytime, so you need to go to 'manual' on the weather channel, and press 'lock-out' so that it isn't on during scanning. You can still manually go to that channel, but it won't stop while scanning that way. Good luck.

I can only get channels 600 through 900 which I have never see before.I cannot get regular channels or cable channels.It is not a flat panel t.v.Q1435A is the model number


Hi -

If you have a cable TV line connected directly to the TV, an antenna or a cable box connected by coaxial cable, I would suggest running the automatic channel scan (AUTO-PROGRAM) again:

1. Press the AV key on the Advent remote control repeatedly until TV is displayed in one corner of the TV screen. If you don't have the Advent remote, use the TV/AV button on the front of the TV.
2. Press the MENU key on the advent remote or the front of the TV to open the on-screen menus.
3. Use the CH+/- keys on the remote or on the front of the TV to highlight PRESET then press VOL+ to select.
4. Use the CH+/- keys on the remote or on the front of the TV to highlight ANTENNA then use the VOL+ key to select either AIR (for antenna) or CABLE.
5. Use the CH+/- keys on the remote or on the front of the TV to highlight AUTO-PROGRAM then press the VOL+ key to start the automatic channel scan.

Once the channel scan is complete, the TV should automatically return to viewing the first channel found during the scan. Do not press the MENU key during the scan or the scan will not complete.

If you are using a cable/satellite receiver and it is connected to the TV by any means other than a coaxial cable, you do not need to run the channel scan. You should simply select the correct AV input using the AV key on the remote or the TV/AV key on the front of the TV (see step 1 above).

If you have done all of the above and you are still unable to get the channels on your TV, please post back for further assistance. You can reply to me by clicking on "Add a Comment" below your question. Please let me know whether you are using a direct cable line, antenna or cable box, etc.

Regards,

I need to do a channel scan on my tv to get the service working but i cannot find channel scan options on the menu. Where is the channel scan option on the sharp LC-32SB24?


During power up and first time use, there should have been an option for channel scanning as the initial setup wizard began.

ec12f55.jpg

Alternatively, there should be a way to navigate to the channel scanning menu by selecting, Menu>TV>Auto Channel Search. I couldn't get the exact info from the model you listed, but I gathered this info from a similar owner's manual (lc-32sb28ut) from the Sharp webpage: http://www.sharpusa.com/CustomerSupport/ProductDownloads.aspx

Hope this helps.

Wanted manual realistic 2010scanner


The realistic 2000 series scanners do not have a "VFO" (variable frequency occilator) in the true meaning of the sence. This basicly means that they can only scan the channels or memories that you have programmed.

You can however set a low frequency (like 144 Mhz) and a high frequency (like 145 Mhz) and the scanner will "bounce" between the two, picking up anything in between.

Do you have the operating manual? If not, here is a copy

Turn on your Pro-2010 by rotating [VOLUME] clockwise. (When first turned on, your Pro-2010 may start scanning).
Rotate [SQUELCH] fully counterclockwise. You'll hear a rushing noise from the speaker. Slowly rotate [SQUELCH] clockwise until the noise just stops.
You're now ready to start entering frequencies.

Programming Frequencies
Before programming frequencies, make sure your Pro-2010 is turned on and the SQUELCH is adjusted.
Suppose you want to program Channel 1 to receive 162.55 MHz. Here's how you would do it:

1. Press [MANUAL] and select channel 1. You can do this in two ways:
press [MANUAL] continuously until the Display indicates Channel 1 or
by pressing [1] [MANUAL].

2. Press [PROGRAM] to enter the programming mode.

3. Enter the desired frequency. In this case, press the [1] [6] [2] [.]
[5] [5] keys. Check the display to make sure the frequency it shows
is the one you meant to program. If it is, press the [ENTER] key.

4. To add more frequencies, just press [PROGRAM] to advance to the next
channel and follow the steps above.

5. If you ever want to change the frequency entered for a specific
channel, just enter the new frequency "over" the old frequency using
steps 1, 2, and 3.

Make a mistake while entering the frequency? Just press [CLEAR], enter the correct frequency and press [ENTER]. If you're entering a new frequency in place of an old one, the old frequency won't be "erased" when you press [CLEAR]. It will remain stored on that channel until you correctly enter a
new frequency and press [ENTER].

You'll hear a "peep" sound as you press the various keys. This lets you know the key has been properly "entered" into your Pro-2010.

Using the Scanning Function
Your Pro-2010 will automatically scan all the channels you've programmed and stop whenever it finds a signal. To scan channels, just press the [SCAN] key.
To stop scanning, just press [MANUAL] and you can select specific channels
you want to listen to.

IMPORTANT! Your Pro-2010 won't scan unless SQUELCH is set to the point where no sound is heard if a signal isn't being received.

Delay Function
When your Pro-2010 is scanning, it will stop whenever it finds a signal on a channel. As soon as the signal ends, the scanning function will resume. Most communications heard will be two-way. To make sure you don't miss any replies, press [DELAY]. This will cause your Pro-2010 to stay on a channel for two seconds after the end of a transmission, giving you time to hear any reply. To release the Delay function, just press [DELAY] again. The Delay indicator will show on the display when the Delay function is used.

Lockout Function
You may want your Pro-2010 to "skip over" certain frequencies while it's scanning (such as continuously transmitted weather broadcasts). To "lock out" such channels, follow these steps:
1. Press [MANUAL] to stop scanning. Continue to press [MANUAL] to
advance to the channel you want to lock out.

2. When you reach the channel, press [LOCK OUT]. The display will show
[o] to indicate this channel will be skipped over during scanning.

3. To release the lockout, press [MANUAL] to stop scanning. Advance to
the channel that is locked out and press [LOCK OUT] once again. [o]
will disappear from the display.

If you use the lockout function on all channels, scanning will be impossible - you'll only be able to change channels using [MANUAL].

Speed Selection
Your Pro-2010 will normally scan channels at a rate of four channels per second. If you press [SPEED], channels will be scanned at a rate of nine per second. Press [SPEED] again to return to a rate of four channels per second.

Priority Function
You might want to scan other channels yet not miss a call on a channel of particular interest to you (police, fire, ambulance, etc.). The Priority function will let you scan other channels - but if a call is received on the Priority channel, your Pro-2010 will automatically switch to the
Priority channel!

1. Only Channel 1 can be used as Priority Channel: Key in the desired
Priority frequency into Channel 1.

2. Priority function works only when the unit is in Scan or Manual mode.

3. Press [PRIORITY] to start Priority function. A [P] will appear on the
display.

4. Press [MANUAL] or [SCAN] to listen to other channels. Your Pro-2020
will check the Priority channel and switch to it if a signal is
received on it.

5. To cancel Priority function, press [PRIORITY] again. the [P] will
disappear from the display.

SEARCHING WITH YOUR PRO-2010
One great feature of your Pro-2010 is its ability to "search" for frequencies being used. This means you can hear all the action on the airwaves in your area! To use this great feature, just follow these steps:
1. Press [PROGRAM] key.

2. Press [LIMIT] key. Enter the lower limit of frequency range to be
searched (such as 45.00 MHz). Press [ENTER].

3. Press [LIMIT] key again. Enter the upper limit of frequency range to
be searched (such as 46.00 MHz). Press [ENTER].

4. Press either [up arrow] or [down arrow] to start Search. [Down arrow]
will start search from the highest frequency and go down. [Up arrow]
will start from the lowest frequency and go up.

5. You can control the speed of the search by using the [SPEED] key to
accelerate or to slow down the search.

6. Search will stop when a frequency is found with a signal. To restart search, press [up arrow] or [down arrow]. In Program Mode, search range will be displayed each time [LIMIT] is pressed. It is impossible to change the lower frequency only: to change lower frequency you must change higher frequency first. The higher frequency can be changed any time.

Storing Frequencies
If you want to enter some of the frequencies found during search, do this:
1. Press [MONITOR] when your Pro-2010 finds a frequency you want to store.

2. Use [MANUAL] key to select a channel to enter the frequency your Pro-
2010 found. The display will show the frequency currently stored on
the channel, but don't worry - the old frequency will be erased when
you start to enter the new one.

3. Press [PROGRAM].

4. Press [MONITOR] again. The new frequency found during the search will
be displayed.

5. Press [ENTER] to put the new frequency into the channel in place of
the old frequency.

6. Press either [up arrow] or [down arrow] to resume the search. To
return to manual or program operation, press [MANUAL] or [PROGRAM].
To resume the search from one of the limit frequencies, press [LIMIT]
and then [up arrow] or [down arrow].

Error Indications
Sometimes when you try to enter a frequency for a channel or as a search range limit, you may find an ------ on the display. This means the frequency is in error and you won't be able to enter it into your Pro-2010. Such frequency errors usually mean you've entered a frequency outside the ranges your Pro-2010 operates on (such as 225.00 MHz) or you've put the decimal point in the wrong place (14.682 MHz instead of 146.82 MHz). Check carefully to find your mistake and then press [CLEAR]. You can now enter the correct frequency.

Hope this helps,
