What to do if my Sony TV has no picture and no sound?
First, verify the power cord, antenna, and VCR connections. If the connections are correct, press the power button to ensure the TV is turned on. If it still doesn't work, try turning the TV off using the main power button for about five seconds, and then turn it back on.
Why does the Sony TV screen sometimes go blank during channel change?
The blank screen during channel change on your Sony TV is normal. The “Signal Booster” is detecting a weak signal, which does not indicate a malfunction.
Why does my Sony TRINITRON KV-SZ29M80 TV cabinet creak?
Creaking sounds from your Sony TV cabinet are normal. Changes in room temperature can cause the TV cabinet to expand or contract, resulting in noise. This does not indicate a malfunction.
