JVC PD-42WX84 42 in. HD-Ready Plasma Television - Answered Questions & Fixed issues

This is a screen with a media box. The box has two connections to the display panel. The first looks like a DVI connector. The second is the proprietory control port connection. This is how the set receives commands about brightness, contrast etc, scaling, aspect ratio. It might even control such basics as power on/off. You could try the panel just with a DVI connection, but you will have to make sure that all sources are scaled to the panel's native resolution (1024x768) before they reach the screen. This is part of what the media box does. You might be okay if you're driving the panel direct from a PC graphics card. But if you want to run it with a variety of different sources then you really need to use the JVC media box. I can't say if the Hitachi media box would work.

???

no kidding? what is the problem so prevelant in this unit? obvious design flaw.

Plasma tvs are tricky for picture. They use two boards to burn the plamsa gas instead of one (LCD)...This almost doubles the price for any replacement boards, unless you know componenet level repair.


Overall, if you can find someone that will work cheap and knows what they are doing...then yes it isn't the most intence repair...but if NOT...then it's probalby too expensive to buy the replacement baords.


Thank you!~

yes the convergence ics are crooked ( big rectangular shaped mounted on heat-sink). you can order them online. check for any open resistors on the output pins.

dds426's reply:

The problem was not a cable connection. A chip needed to be replaced at the tune of over $600j (includes $200 for the repairmen coming to my home to dismantle and take to the shop and return it).

Your TV needs to be calibrated. Rear projection TVs are very sensitive to movement. They have 3 color canons that need to be precisely aligned so that the colors overlay each other. They are like three projectors all aimed at the same screen.

If you were to enter the User Menu on the TV, you should find an alignment/calibration choice that will re-align the colors using some on-screen help.

If you are not able to resolve the situation on your own, a certified ISF Calibrationist should be called.

And, since you've bought this TV used, it should be cleaned by a professional (the canons, lenses, etc.)

Note
In some cases, there are minor defects in some parts of the screen. Points that do not light, points with
brightness different from that of the periphery, or points with color different from that of the periphery.
Some pixels will always be on or always off. Please note that this is not a malfunction. So what this says is that it's not the Plasma Cell problem, its more like a bad board inside. You will need more info like schematic and find out which area the bad part is in.

Hello gladwin6,

You may have at least a blown fuse. However you may also have other damage to your power supply. This often happens due to the voltage spike caused by the power coming back on suddenly. You can check to see if the fuse is blown, however once you change the fuse and if this does not take care of the problem, I would suggest that if you do not have a background in electronics, that you have a qualified technician take a look at your TV set.

I hope this helps,
Thank you,

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.

Here are some troubleshooting steps you can try to fix the sound issue on your JVC TV:

1. Check the volume level: Make sure that the TV volume is not muted and the volume level is high enough to be audible.
2. Check the connections: Ensure that the audio cables are properly connected to the TV and the external speakers. If you're using an external audio device, check its connections as well.
3. Try resetting the TV: Turn off the TV and unplug it from the power source for a few minutes. Then plug it back in and turn it on.
4. Check the audio settings: Access the TV's audio settings menu and ensure that the sound mode is set to "Stereo" or "Mono". You can also try changing the audio output settings to "TV Speakers" or "External Speakers" depending on what you're using.
5. 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.
