Hi,
Problem seems with tuner in tv that can not process a little weaker signal hence tv shows *weak or no signal* message on screen.
Ask your dealer to increase AGC level of tuner as dealer would have contact tv repair shop/ tv technician to do so.
Hope this adjustment will solve your tv issue or replace tuner board in tv to fix the issue.
Thanks.

My sony tinitron kv-t25sf11 turns on but no picture or sound, just snow, cant find any channels on autotune. when i turn to av channel, then back to tv i get audio from a channel for half a second before...


There can be few suspects for this fault but ONLY a signal test will confirm the exact part.
1. It is possible that the TUNER is faulty , if so the AV must work with good clarity.
2. Also the IF section can be faulty, it can be the IF processing section or the data switching from the processor.
3. It can be a digital logic gate switch failure as the processor is unable to switch from AV to the TV RF section.
4. Tracing using a signal or tracing with a scope can confirm the section. You can check at the AV switching section for a possible fault.
Thank You

The screen shows ''Weak Signal'' and no picture, even though audio is coming through from both the Cable DVR box and Blue-Ray player. The cable box connects to the TV with an HMI cable - all five TV inputs...


Mine did the same thing once. I think all I did was hit the setup on the remote, and let it run back through all the channels and then it worked just fine.

I hope this works for you.

The problem with saying my TV is acting up, is you did not mention the model #, type of TV, tube type, projection, plasma, LCD. They all have different faults that can cause this. The first thing you do is to hook up signal to your video inputs if you have any and see if the signal works that way, if so then you probly have a bad tuner, or you cable box is bad.

Picture shows snow and fuzz on channels JVC AV-32980


Sounds like U have an antenna or feeder problem. Get it checked out/ check it out. If in a strong signal area, try a simple indoor antenna for comparison. If in a marginal reception area, it could be your antenna is inadequate.
