Question about Sylvania LC420SS8 LCD TV
I,have to turn on tv manually. change input manually,tv reception is ok. Volume cannot be controlled,it will lock in at full volume or drift back & forth,mostley full volume. If I use volume buttons on tv , it changes input (video 1 pc hdmi & so on) Once in a while setup screen will appear then disappear. I have changed batteries in the remote, I don`t believe this is the problem.When tv is first turned on the volume icon at bottom off screen will go from 0-60 and hang. since I cannot get remote to work with tv I can`t use mute button. The problem apppears to be in the tv itself?

Try doing this:
Self-check indication only:
Produce TV reception screen, and while pressing [VOLUME ( - )] button on the main unit, press [OK] button on the remote control
for more than 3 seconds.
Self-check indication and forced to factory shipment setting:
Produce TV reception screen, and while pressing [VOLUME ( - )] button on the main unit, press [MENU] button on the remote
control for more than 3 seconds.
Disconnect the AC cord from wall outlet.
This is straight out of the service manual.
