How can i solve or troubleshoot my jvc 21 inch
If thhe ic has a crak that you can see then it is no good replace the ic If looks good then look real close where it is soluder ontothe board for little crakes in the soluder where the pins are. I would resolder the ic anyway becouse some thime you cannot see the crakes but the pins are loose. Now there is some capasistors in that cerit also that go bad.You would ned a capasistor checking machine to check these out of cerit.These capasistors that im talking about are usley black with writeing on the side like 10u 25 v this is not for the ones you have in your set just trying to let you know what im talking about. There is a pos and neg side to this kind of cap and they have to be put in just the way they are took out. Try resoludering the ic first then see what happens if it looks ok, if that does not fix it replace the ic and caps. This ic will be mounted to a heatsink by the way.

How old is this TV?
As Tv's age, the high-voltage suffers and they get darker. You
can turn up the screen adjustment on the flyback transformer and buy
some time but:
My experiance is to not put money into a TV that is over ten years
old. TVs stress out their electronic components worse than almost
any other electronic product. After 10 years, there are so many
parts that are ready to fail that your are probably wasting your money
trying to get any more life out of it.
Another option is to wholesale replace the main board from an outfit like Module Exchange at 972-298-1212
Be careful on buying a new one though. Often times, these new
technology ones are much worse. Always Google the model number of
the set you intend to buy and add the word 'repair' or 'complaint' to
see if it is one of the many models that are customer service
nightmares being produced by even the most reputable companies today.
Hope ya fix it!
Color problem
Please fine tune those B/W channels to obtain color picture. If TV is more then 4 - 5 years old, it needs resoldering in tuning area or might need replacement of IF block.

Hi there!
The Video circuit or chip that runs it may be at fault. Refer to a repair technician if not familiar with TV repairs. Good Luck, JUS004

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.
