There's a picture on the screen, but it has lines all across it.Sometimes it will be clear, but most of the time it has lines. I also have directv, but they've installed a new box. Is this my television...


Hello
If the lines are there, and are across the screen at about an inch apart the whole screen from top to bottom, it is due to a slight increase in your TVs screen votage. It can be adjusted.
Open the back cover of your TV. There is an LOT [Line Output Transformer], can be seen directly soldered to the printed circuit boar of your TV. It is the largest component inside your TV, which have usually three wires emerging from it, and one thhick wire goes to the final anode of the picture tube, and will seem to be sticked to the top of the picture tube with the help of a rubber ******. Other two wires goes to the base card of the picture tube, a circuit board.
The said [LOT] has two controls integrated on it facing you as you open the TV. Among the top one is focus control, and the bottom one is screen control. Both of them are variable resistors, help to adjust focus and screen voltages respectively.
As set powered on, keeping the brightness, contrast and colour controls to its minimum, turn the screen control a little bit counterclockwise [not more, a little bit] will eleiminate the lines on your TV screen.
Take every precautions we have to, when working with an electrical equipment. Keep children away from you while you are working on it. Never allow them even to come beside you. Keep an adult beside you as a precautionary measure. Ok.
Wish you all sucess.

How do I adjust the screen to the TV - I've looked in the MENU options and can not adjust the height of the screen. In other words - I can not read the score ticker on the bottom of the screen


Your sanyo tv may have service mode adjustments. It can be taken according to the sevice code options, which can be get from service journals available in the market. no menu adustment is there to adjust the picure linearity, height , subbrightness control so on. All adjustments are coded and have critical measurements which can be adjusted through service mode with the help of remote control. The remote control should be orginal to access service mode. Duplicate may not work properly.

Hello paulaspec,

You have a problem with the three factors, and they are screen voltage, focus voltage, and control (focus 2) voltage. Basically these voltages have to be adjusted since the components in this section have aged some. These controls are usually located in the television on the IHVT (Integrated High Voltage Transformer) or as it is also called the flyback transformer. these controls must be adjusted together, along with the color controls. Here is how the adjustment is done (You will need a schematic diagram, a DC volt meter, and a color bar generator to do these measurments):

 

1) turn color and tint fully counter clockwise until you have a black and white picture.

 

2) connect the color bar generator to the TV (ch 3) and turn it on, you should see bars in various shades of gray

 

3) adjust as best as possible the color and tint controls to obtain the color bars on the screen Red Green Blue.

 

4) measure the voltages on the focus, screen and control grids of the CRT and match them to the schematic digram measurements.

 

5) adjust the focus screen and control grids to match the ones on the schematic diagram

 

6) once this is done then you adjust the color controls once again to obtain the red green and blue bars on the TV screen.

 

This should help if the CRT (picture tube) electron guns are still good and if the flyback transformer voltage supply is working.

 

However if you do not have a background in electronics please take the TV to a shop for repairs.

 

I hope this helps,

Thank you,
