How do i fix a non responsive tv set?


Do the ballast first. That should get the picture back. The main board controls everything else.

Volume intermittently increases all the way to 100 and cannot be controlled by the remote


This happens with some models. You can open the TV from the back and disconnect the connector for the side control board. You will only have control via the remote but your volume issue should be resolved.

I have a denon 1801 and the master volume goes to +60 which is all the way up and i cant seem to lower it, the knob turns and everything else works just fine


First solution would be to try and use the remote. If the remote is able to, the problem is in the knob. If the remote does not work, the problem resides in the volume board.

The problem resides in the circuitry that the knob is controlling. Unfortunately this knob has a full range of motion, which means that it is simply controlling a computer chip within the unit. (i have an 1801 as well). What has happened is that some component on the volume board has gone bad, which is resulting in your non functioning volume knob.

Unfortunately this is usually a job for a professional.

If you have standard electronics skills (soldering / disassemble / reassemble), you can open the case and find where the volume knob leads to. There should be a smaller board, and see if you can access it. Usually they are rather hard to get to, or to get free to actually see what is going on. The best solution would be to find a parts receiver, and swap boards. This shotgun approach changes everything. Otherwise, look for any damaged components on the board. Swap out any components that are damaged, or appear damaged with comparable replacements.

Static electricity fried the button panel


static electricity can damage the chips on the boards. it all depends were the static voltage went to, if it was just to the buttons controller board or to the main av board. you could need new button board or you could need to replace the main board and the button board its hard to say with static shock.

Volume is intermittent


If anything works after it is moved suspect a bad solder joint somewhere.

Problem with remotes for our zenith e44w46lcd tv


It could be that the main board or the remote reciever is bad on the TV. The best thing to do at this point is to have a technician verify which one is causing the issue. Otheriwise it would be an expensive gamble to replace both boards. Please take a moment to rate my answer. Thanks..

All remotes controlling my Onkyo TX-SR304 stopped working


try putting the remote an inch away from the IR receiver on the unit and see if it works then, if so then you definitely know its broken. This can and does happen. From what you have posted it sounds like no remote is working on the receiver, the ir receiver can break. If you need further assistance let me know.
Thank you,
Lee

Volume can not be increased low static sound


No / intermittent audio is caused by vibration damage to the audio circuit. Unit needs to be put under a microscope and inspected for micro cracks in the solder joints of the audio circuit components.

Volume control is adjusted by remote switch on handle bar. You can contact HD for a wiring harness schematic
