I'd be curious to hear where do the other guys found those 12V/500 mW.I am holding in my hand a transient suppressor from an LCD TV power board with two lines on it - the first is saying LT7232 and the second is P6KE120A.I can't find a reliable reference for LT7232 anywhere through Google, however P6KE is a well known series of transient suppressors and I am ready to bet this is the proper component here. Hope this helps avoid confusion.www.coppelltvrepair.com

It sounds that the main power supply section to your TV has the fault. The horizontal thik lines that appears crawling down across the screen should be of video 'HUM'. Have you replaced the main filter capacitor at the power supply section? If not, replace it along with the main rectifier. The AC power is rectifed by a bridge and applied ot this main filter capcitor. It will have a capacitance value between 120 to 350MFD 450VDC. Check this section. Measure the rectifed DC voltage acorss this main filter capacitor. It should be around 350VDC, if your home power supply line is 220VAC. If it is 110AC, this DC voltage will be around 165VDC; and it should be. If rectified DC voltage found lower than the input AC voltage, replace the rectifier bridge. In some sets, this bridge section have four diodes. Some other circuits, a bridge rectifier stalk may be used.

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.

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.
