First, check the cord if there is leaks, scratches, and is loose. If cord is intact, check the plug, have a multimeter tester and check the continuity of the two ends of the plug. If it is reading then there is no problem with the plug and the cord. Have this being done and inform me then of the outcome.

The most likely problem is bad solder connections to the vertical output integrated circuit. This device gets hot under normal operation, and the heating can eventually cause the connections to go bad. This can cause a complete collapse of the picture like you have, or a shrinking or bouncing picture. Often just repairing the connections solves the problems, although the IC itself does also go bad and needs replacement.
If you know someone with electronic soldering skills, you might be able to try fixing this yourself. The IC is mounted on a metal heat sink in roughly the center of the circuit board. There will be a number on the IC like LA7847 or LA7848. I don't remember exactly what IC this model uses. You will probably see the solder connections are cracked, and resoldering them may be all that's needed to restore the picture.
If you don't feel up to trying this yourself, it's not a difficult repair for a professional technician, but labor cost may make it uneconomical for a small set. See if you can get an estimate for the repair from a local service shop, then decide whether to repair or replace the TV.

My JVC TV has an onscreen remote that doesn't let us use the actual remote what do I do to gat it out?
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:
- 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.
- 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.
- 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.
- 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.
- 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.
JVC SR-DVM700U the front display is dimming quit low to where i cant read it
If the front display of your JVC SR-DVM700U is dimming to the point where it is difficult to read, there are a few potential causes and troubleshooting steps you can try:
1. Adjust the display brightness: Check if your device has a dedicated display brightness control. It could be a physical knob or a setting in the menu system. Increase the brightness setting to make the display more visible. Refer to the user manual for specific instructions on how to adjust the display brightness.
2. Check the power source: Ensure that the device is connected to a stable power source. If the power supply is fluctuating or inadequate, it can cause the display to dim. Try plugging the device into a different power outlet or using a different power cable to rule out any power-related issues.
3. Clean the display: Dust, dirt, or fingerprints on the display surface can also affect visibility. Gently clean the front display using a soft, lint-free cloth. Avoid using harsh chemicals or abrasive materials that could damage the display.
4. Check for backlight issues: The display might have a backlight that illuminates it. If the backlight is malfunctioning or failing, it can result in dimness. Unfortunately, in most cases, repairing or replacing the backlight requires professional assistance. Consider contacting a qualified technician or JVC customer support for further guidance and potential repairs.
5. Reset the device: Perform a factory reset on your JVC SR-DVM700U. This can help resolve any software-related issues that may be affecting the display. Consult the user manual or contact JVC customer support for instructions on how to perform a factory reset on your specific model.
If the above steps don't resolve the issue, it is recommended to reach out to JVC customer support or consult a professional technician who specializes in JVC audio/video equipment. They can provide further troubleshooting guidance or recommend appropriate repairs if necessary.

- Check the volume level: Make sure that the TV volume is not muted and the volume level is high enough to be audible.

- Try using a different audio device: If the above steps don't work, try connecting a different audio device to the TV to see if the sound works. This will help you determine if the problem is with the TV or the audio device.
If none of these steps work, it's possible that there may be an issue with the TV's audio hardware, and you may need to contact a professional repair service or the manufacturer for further assistance.
