Check and replace the chroma IC.

Hello Jim O'Connell,Welcome and thank you for using FixYa!To answer your question: I would suggest having a television repair professional pull out the power supply board.They will need to remove the board and check it for bad (cold) soldier joints, bad capacitors, and lastly, to use an Osilliscope to test the +5v and -5V transistors on the board. If they can't diagnose the board, they can use the part number to order and install a replacement for you. That should fix your issue.Have a great day!

Good day sir, its a different issue, about the capacitor, for as long as your replacement part is correct, it will work, now, there are several things you should check, the I/O device that controls the inputs of the TV, usually an IC, check your schematic diagram to trace the fault. check also the line from the input 3 to the controller IC on your diagram. Measure the voltage across the IC Vcc to ground if the IC is getting the right power, Low voltage can be cause by faulty capacitors, on the power supply line, or the IC itself is faulty, Circuit analysis and voltage measurements are needed to trace the faulty part. hope this helps thanks.

If the TV goes off completely, then is usually a faulty power board.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

Sounds like you've got whats called a cold solder connection somewhere in the horizontal width control circuit or a connection in the sweep section. Should'nt be two expensive but unless you have had some soldering and troubleshooting experience I would leave this on to the pros. Good Luck

you probably have some sort of overheating or short on the internal board - is it still on warranty? if so they will fix at no charge - if not, a local repair shop should be able to correct the problem but it may cost as much as $150

The picture tube on a TV can be magnitized by the Earth's magnetic field. The noise heard when you turn a TV on (usually followed by a static noise on the face on the TV) is called degauss. What this does it remove any magnetic variations on the tube due to things like the magnetic field and speakers. However, changes to the TV in orientation to the Earths magnetic field will cause the tube to have a magnetic bias. This is most prominent when turned 90 degrees. The easy way to clear this is to turn the TV off for a little while and then turn it back on. But remember that any movement once it is on can cause the discolorations to reappear. My suggestion would be to turn the tv after you've moved it to the location you'd like to view it.

If none of these steps work, it's best to contact a professional or JVC's service center for further assistance. I hope this helps!

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.

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.
