Thanks so much for posting, saved my kitchen tv from the landfill!... Also the buttons on the side of the tv do not work correctly. ...Any suggestions? .... LG LCD TV REPAIR - NO PICTURESCREEN FIX REVIEW - Duration: 5:29 ...
Your hi voltage circuits are dieing. There are many parts associated with the voltage needed for a full picture. It may or may not be worth the price of repairs on an older TV depending on how old the TV is.
hit your TV on left side or right side or on top & then observe ..........you will get normal picture or it comes & again it goes....if it is happening like that then following is the situation..........after 4 or 5 yrs in some TVs on main board ( also on CRT circuit board ) at some soldering joints crack develops....then due to loose contact picture becomes small in size or abnormal width, or rolls etc ...........when we hit that lightly then those loose contacts joins temporarly & again picture appears normally for some time............so solution is .....TV main board & CRT circuit board should be observed carefully & most of the joints should be re-soldered.......only a good service engineer can do that........even after hitting TV lightly if there is no response then main board has to be checked completely........in your case iam sure it is loose connection problem.........joints should be re - soldered ...100% it works again ................this problem cannot be solved by user unless user has idea about components( resisitors, transisitors, diodes,...etc) , have soldering iron , multimeter & other tools....................so contact good TV service engineer .............iam from bangalore -( computers, laptop, printers, etc )
Most likely you have the dvd part connected through component or svideo cables. Despite the fact that this is one unit, like other vcr/dvd combo units it acts as two separate units in the same box. The vcr will probably not play through those cables. As you have audio coming through I'd imagine that the audio is connected using red and white composite cable. Connect the video on the vcr side with composite yellow cable or run direct to tv with a coaxial cable.
I'm sorry, but the Sansui HDLCDVD320 has no analog audio out jacks. If you have a cable or sat box, etc, you might be able to get audio from their outputs. I hope this helps you.
I have a sansui 19" LCD TV+DVD I had to attempt multiple times turning the TV on to get a picture. The sound was fine. This kept happening when I would go to turn on the set the TV kept playing fine with picture & sound but after the 2nd attemts I turned it off & then tried to turn it back on which took multiple attempts, it kept playing for a few minutes then the picture went out but the sound was still there. The set is not yet 2 years old.
Hi, I have a Sansui Model San1880, after I have manually program the TV channels, I don't get no sound at all only on the TV channels its got good pictures but no sound, would you please tell me what to do.
