The tv is mostly black and white some programs are in color, when I push the minus volume button it goes all the way up then start coming down to 15 , it also goes black when I push any of the volume or channel button. none of the buttons are doing what it is supposed to do...I have to have a booster and it used to work fine.
thank you for your help
Hi,
If you are still receiving good TV signals (though black & white) then chances are the booster is still OK.
Since your main concern is centered around the controls then it is likely that you have a fault somewhere in your logic section. Based likewise in your posting, all the controls work except some other functions are triggered. Since the issue is somewhat general then either the DA converter IC is at fault or its supply B+.
As bestdarngood have posted, knowing your make & model (or chassis #) wold be of gret help narrowing down the problem.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.

HI,
The Tv needs to be serviced by a technician.Probably there is a problem with the circuits inside.
Few troubleshooting steps you can try:
1)Do a hard reset by unpluging all the cords for 4hrs and then plug it back.
2)The
whacking test is to just bang or smack the set with your hand on the
back, side, top, etc., to see if there are loose connections or cold
solder joints inside that are acting up. If so, the banging should
knock them back to normal and the set should restore. You might have to
use some creative banging and some have had to put a book or magazine
under one corner to torque the chassis enough to get it to work
reliably.
try covering up the remote sensor to test that theory and see if the volume button is on stuck.
Another thing you can try:
1) Take off the base and knock it gently to see about possible
loose connections. 2) Remove the backcover of the TV and use pressurized gas to
clean dust of the inner workings. 3) Leave it unplugged overnight to get
the "hard reset."
Goodluck,
Please don't forget to rate the solution
It sounds like the main board is malfunctioning and needs to be replaced. Depending on the age of the tv, you may just want to replace it. Please post the make and model to help us better assist you.
Thank you for using Fixya and good luck
