Connection for cable


A snowy picture is usually an indication of a bad ground. Check the cables at both ends to be sure that the braid(shield) is still intact and connected to the F-connector. Also, check the connections on the exterior of the house. You can also call the cable company and have them check the connections at the poles.

Snowy screen


Hello, The snow is due to a tuner failure, this can only be repaired by replacing or repairing the tuner itself. Your post shows model number PV-DM2793, and the tuner part number is ENG36715G. It's available from several electronic part stores, try johni@ued.net, there is one still available there. The tuner is located directly behind the cable connector(threaded connector)located in the rear of the TV where the cable or antenna connects to, it solders vertically into the main board.

My toshiba tv has shadowy streaks on the screen what is the problem


If your TV is a old picture tube technology type try the following.

The following is for technical experts only
It is EHT cable contact problem.
Switch off TV. Remove all electrical wire connections including antenna cable etc.

Wait for few hours! Open the back cover. You will find a thick red colored cable connected to the picture tube through a suction rubber cup. Ease the rubber and slightly rotate it. Very little only. This will establish a new contact in the picture tube shell. Place the rubber cup in the same way. This just a suction cup and hugs the picture body and air tight.

Now switch ON try. If OK leave it. If not try the same way of waiting.

Failing to observe the cooling period,
You are likely to get High Voltage electric shock as picture tube acts as a storage current for few hours. ( Even switch is OFF )

Hissing sound inside my sansui tv


You have a short on the secondary side of the transformer that is hissing. You are going to need someone knowledgeable in electronics, to help you find the short. Most likely it is your Horizontal output transistor.

I have the 13 inch and...


If you get channels 2 to 13 nice and clear but the rest are snowy, it means that the TV is set to the broadcast channels, which means that for the channels above 13 it is tuning in the old-fashioned UHF channels. If the TV is set to the cable mode then it tunes in cable channels above 13. To do this, enter the menu and navigate to the tuner settings, set the tuner to standard cable and then do the autoprogram, and the tuner's memory will be set for your cable system.

No sound,volume bar works


Sorry I dont have a manual but it is available at http://www.servicemanuals.net If you put your ear close to the speaker, with the volume turned up, do you hear any hiss or buzzing? If you dont it could be a bad speaker,headphone jack(if there is one), or the audio output IC or ascoiatated componets. If there is a hiss, then theres a problem with the audio processor or switching IC. If your not a tech, you should not be experimenenting around inside this TV set!
