G'Day!

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. To discover which part, a service tech at a repair shop would need to be consulted. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher.

Good Luck and Please Rate FixYa!

i would take it to a shop and have them repair it so its done right.they can be funny the way they act but they are normally good tvs id take it in for repair

It would be interesting to know what the $600 got you.
Many of these kinds of failures are attributable to power supply problems and depending on the design of the supply and knowledge of the repair tech, it may be a repetitive problem.
The only way to fix this permanently is via the detailed inspection of the circuit, replacement of the failed parts and often, the addition of certain components to provide some protection of the parts that will likely fail again. Replacing of the supply completely will probably only give you momentary relief until these parts (almost surely chemical (electrolytic) capacitors) before they again fail to perform their designated function.  

I would suggest, since you have some technical background, that you download the manual for your set.
This site seems to have the best prices of any around:

Hello! If your JVC TV is displaying an onscreen remote and you're unable to use the actual remote, you can try the following steps to resolve the issue:

1. Power cycle the TV: Turn off the TV and unplug it from the power source. Wait for a few minutes, then plug it back in and turn it on. This can often reset any temporary issues and restore the functionality of the actual remote.
2. Replace the remote batteries: Check the batteries in your remote control and make sure they have enough power. If the batteries are low, replace them with fresh ones and try using the remote again.
3. Check the remote control sensor: Ensure that there are no obstructions between the remote control and the TV's remote control sensor. Clean the remote control sensor on the TV with a soft, lint-free cloth to remove any dust or debris that may be interfering with the signal reception.
4. Reset the TV to factory settings: If the issue persists, you can try resetting the TV to its factory settings. Keep in mind that this will erase any personalized settings and restore the TV to its original configuration. Refer to the user manual or the manufacturer's website for instructions on how to perform a factory reset on your specific JVC TV model.
5. Contact JVC customer support: If none of the above steps resolve the issue, it's recommended to reach out to JVC customer support for further assistance. They will have access to more specific troubleshooting steps and can guide you through the process of resolving the issue with the onscreen remote.

Keep in mind that the exact steps and options may vary depending on your specific JVC TV model. Refer to the user manual or contact JVC customer support for model-specific guidance.
