20 Most Recent JVC PD-42WX84 42 in. HD-Ready Plasma Television Questions & Answers


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.

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!~

Hi


Thanks for using FixYa. A plasma TV is a very hard working device. It is working harder than any TV that has been built before, and as a result it produces a lot of heat. 75% of technical problems in plasma TV's are caused by overheating problems. You’ll need to check the power supply board first for any swollen/bulged capacitors. As power supply board is the hardest working board in a plasma TV, it develops voltage to supply all components, high current + high voltage. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when switched off. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

From the information you have provided I can say there is a good chance the problem is a failed power supply. Likely caused by bad capacitors. I would expect this repair to be about $350. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly. Small TV repair shops will often charge less than a large repair facility.

Thanks

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.

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,

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.)
