On the tuner, only A.M., there is a buzz when the T V is on. Any thoughts ?

The tv Tuner signal board is the causes and the problems.That the board,where the antenna signal wire plug into it to receive the incomming broadcasting tv signal channels stations.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish tv Tuner signal board for the replacement.

Ur tuner board is defective.Replace the tuner board will solved this problems.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish tuner board for the replacement.

It's just "Digital Audio" vs "Analog Audio" You can use the "Volume Offset" function in the receivers "Main Menu" to compensate for this. Go into the menu then go to audio and or input settings and you can adjust the offset and lock it in. If you still have a problem, post a comment and I can help you some more. There is not a "problem" it's just the way the audio is transmitted. Like when your watching TV and a commercial comes on and BLOWS you out of the room. That's going from clean digital to noisy analog.

check on line, they may have a updated version of the driver.

try replacing av cords..if not replace tv

Hi and welcome to FixYa,

Appreciate the direct "Ask Me". I actually replied to your other post here. Pls find below proposed diagnosis.

Initially, if you have confirmed that the source of the buzzing sound is from inside the TV, then that would indicate a component about to fail or would need attention. Let us try process of elimination:

• tuner - most unlikely, the tuner is responsible for selecting the channel. No component/part of the tuner could make such a mechanical buzzing sound;
• speaker(s) - most unlikely, the speaker could have a buzz but generally would not affect the video nor cause snow (weak TV signals);
• transformer - a strong possibility although without knowing the exact model, at most generic ideas; power transformer, flyback transformer, horizontal drive transformer (unlikely);
• arcing - another strong possibility. This could be caused by damp, dusty surroundings of the components especially at the FBT area. Another area that could have adverse effect when dusty/damp would be the anode cap.

This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

This is an indication of a bad ground connection. Since you have replaced the cable and splitter, it suggests an internal grounding problem. If you can solder and can get to the tuner, resolder the ground points within the tuner and update this with the results.

use roll back driver see its work do you knew how to roll back

reset your tuner. Call the cable co for instructions...accordianman
