What to do if my Sony TRINITRON KV-HW212M60 has no picture and no sound?
If your Sony TV shows no picture and produces no sound, first check the power cord, antenna, and VCR connections to ensure they are properly connected. Also, make sure the TV is turned on by pressing the power button. If the TV does not respond, try turning off the TV for about five seconds using the main power button on the TV, then turn it on again.
How to fix a Sony TRINITRON KV-HW212M60 with a snowy picture and noisy sound?
To resolve a snowy picture and noisy sound on your Sony TV, start by checking the antenna cable and its connections at the TV, VCR, and wall. If the connections are secure, verify the antenna setup is appropriate. If issues persist, access the “Channel Setup” menu, select “Manual Program,” and preset the channel again. If the signal transmission is weak, go to the “Channel Setup” menu, set the “Signal Booster” to “Auto” from “Manual Program”, or try using an external booster.
Why is my Sony TV picture distorted with noisy sound?
A distorted picture and noisy sound on your Sony TV may be due to overly strong broadcast signals. If you're using an external booster, try turning it off or disconnecting it. Alternatively, access the “Channel Setup” menu and set the “Signal Booster” to “Off” from “Manual Program.
What to do if my Sony TRINITRON KV-HW212M60 has good picture but noisy sound?
