Problem with flat screen tv picture

This is a sudden problem with our Vision Quest 'Renoir' 39" flat screen TV. There is a solid block of colour that appears vertically from the top to bottom of TV that covers about 25% of the picture. It's there and then goes away and comes back. TV isn't very watchable. I just want to know if this is common or worth fixing (we bought the TV used for $150) or if it's time to buy a new TV? Help please!

Sounds like a possible "cold" solder joint on one of the circuit boards.
Majority of these intermittent problems is caused by either a broken solder joint and can be fixed if you inspect the different boards that
are present in your unit. Use a magnifier to help you find these "cold"
or "broken" solder joint(s). You will also need a soldering iron (~40W)
and some solder to reconnect/reflow these broken joint(s).

SOURCE: 43'' SAMSONG FLAT SCREEN. SHADOWS RADOMLY APPEAR

Is your tv a plasma tv or an lcd tv? When you say shadow, do yo mean a band across or down the screen, or is it a patchy shadow?

SOURCE: BLUE VERTICAL LINE

The address module that is at the bottom of the PDP in that location is the suspect and the cheapest repair. There is usually 3 to 4 modules at the bottom of the PDP and each one addresses information vertically. If it were just one pixe wide then the PDP would be bad.

SOURCE: dark vertical shadows

No,you can't. This is very common. I bought a new tv and i noticed right away that it had the problem you are mentioning. I took it back for an exchange and the next tv did not have this problem...until a year later. Now,of course it does have this problem,but it is out of warranty.

I think they make televisions very poorly today.

SOURCE: samsung 42" Plasma -Black vertical line when turned on.

It sounds like an Intergrated Circuit (IC) has fried. Even on a good day, this is not something you can attack at home. As a tech (and as an owner of that model samsung), I'd need a map & tools to know what's going on. Your best bet in this situation is to contact Samsung and let them recommend an authorized service center in your area. Sorry I can't be of more help, but this is a rather serious problem.

A horizontal white line is appears in my LG Flatron colour tv in the middle of screen suddenly and the pictures disappears but the sound keeps on but when i restart the tv the pictures comes what would be...


Tap the top of the TV and if the picture comes on in full screen then it is possible that there are DRY SOLDERING points on the board.
use a good iron to touch up the soldering on the vertical and horizontal sections, the driver IC's. get help if you are not able to do the job but it seems a minor job.

Following the beginning of digital switchover, pressing the menu button only comes up with 'picture quality' and is unable to access 'installation'.


If your TV is not in Digital it won't give you the tuning option.
Select DTV from the on screen menu, (like scart 1 scart 2 etc). When you have found DTV select it and then press menu for tuning.
Hope that helps.

Tv code


The Innovage Jumbo remote control manual does not list any TV's by the manufacturer Vision Quest, but that does not mean your TV is not compatible with another brand's control codes. I recommend using the auto-search function to see if any of the remote's TV codes work with your set.

To have the remote try each TV code it knows one at a time, follow these steps:
  1. Turn on your TV.
  2. Press and hold the CODE SEARCH button for at least 3 seconds until the red LED lights up and stays lit.
  3. Press the TV button on the remote so that the LED blinks once and then remains solid red.
  4. Press the ON/OFF button slowly and repeatedly until the TV turns off. The LED will blink once each time you press the ON/OFF button.
  5. Once the TV turns off, press the ENTER button to store the code and the LED will turn off.
I hope that helps.

It sounds like there is a problem with the tuner inside the television. Your best bet is to send it in for service.
