Flatron Plus. Why does it have "blinking" sound and LED?


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

Why is my Sansui Sv2918 tv constantly blowing the line output transistor


Try using a higher voltage for the replacement cap. Usually factory uses exact voltage but that can not handle surges.

Picture keeps freezing


There is a few issues that can result in picture freezing
1: Overheating, keep it in a open area away from other devices
2: Your coax line from the cable company is going bad, if the rest of your TV's in your house are ok then its the one line itself going to that box, it could be an older 59 line or the fitting on the line needs to be changed.

Y/Pb/Pr outputs are green; needs


There is no calibration for the component video that I know of, check your cables you may have a bad Pr cable or the Pr/Pb ones may be mixed up.

Y (the green one) is for luminance, plug in ONLY this connector and you should see a black and white picture.

Now connect the Pr. You will now see red tones.

Now connect the Pb. And you will see blue tones.

Reverse the Pr and Pb and see what happens.

Oh and make sure you don't accidently have one plugged into a composite video or digital audio port.

Still not looking right?

Go into the input menu of the TV and change the component (or colourstream) input from RGB to Y/Pr/Pb. (most TVs do not have this feature.

Hope this helps!

Dish 722ViP questions


You sure describe a bad receiver to me. Press MENU-6-1-3 and select details. Scroll down the page and you will see a section of VALUES 1-9 all should be zeroed except 7 which should not be over 4 and 8 at 1. If yours reads anything greater you will need it replaced.

Call in and ask for a Field Service Manager, Installation Manager or Quality Assurance Specialist to come to your home due to unresolved issues. To ensure you get a response e-mail or call the corporate office describing your situation. Do not call the toll free number for the corporate office as you will not get them.

We are unable to give numbers out so you may need to do some research of your own.

Thanks for using Fix Ya.
