Question about Symphonic ST4813 13" TV

1 Answer

What is it called.

I need to know what the older TVs were called. The ones with the bump in the back. Not the flat screen. Have an old one that still works but some one gave me a newer TV and I want to list it at work to see if some one wants it. Thought a description would help.o

You haven't specified here about the channel capacity or both of your Televisions. Is both of it can receive 100 channels. If not, the tuner to both will have the difference. There are sets with which can receive only 50 channels, 90 channels, 120 channels etc: Older versions of TVs will have only low channel capacity. Present ones are of channel receiving capacity up-to 320.
If the channel receiving capacity to your TV is low [as it is older models]; there is nothing more to do. Electro help

An older tube model - audio okay, no video - only a narrow line across the middle horizontally

Sad to say this is likely the death of it.
Technically, the time base line output has ceased to function.
Unless you feel it's a full blown crusade to have a vintage working TV you're going to have a hell voyage (unless you're extemely lucky) of cost in time and money to get that put right which you may decide aint' a road worth going down.
Better to put your money into a new flat screen TV but if you've the storage space don't scrap the old TV. Depending on it's present age it will be worth something soon to a collector or theatre/TV/movies props hire supplier.

I have an older Sharp TV. The color of the screen all of a sudden has darkened some. Is there a way on the tv to lighten the screen? Thank you!


This problem can result from the aging of various components within your set, in general with older TVs, particularly sets of 15 years or older for example tend to suffer from capacitors that degrade - effectively reducing the maximum level of picture illumination available. Another issue for old sets that have been used extensively is that of the picture tube's electron gun aging, over time the gun produces fewer electrons to fire at the phosphor coating hence causing less "glow" - this can be sometimes improved by adjustments to the tube. All in all the set may require a decent service to ***** what aged components need replacing. Some later TVs do have a trimpot on the flyback transformer to allow the tube's brightness to be increased, but most older sets lacked this feature. SHARP did have this feature on many of it's 90s TVs but it needs to be adjusted with care by suitable techs due to the dangerous voltages present.

Hope this info is of some help, Regards.

If you have cable running to your house, cable still uses RF and older TVs work fine. The problem comes when you try to grab stations from the air. The signal is still UHF, but the information riding on that UHF signal is digital, and will need a converter box to turn it back to analog so your older TV will understand it. . Cable: None needed. . Antenna: Need a box.
