Here's a link to order the original the JVC upper Y-buffer board and lower Y-buffer board for this model from a major parts distributor if needed:


JVC "PD-42DX6" Replacement Part Upper Y - Buffer Board (LJ41-02760A)

JVC "PD-42DX6" Replacement Part Lower Y - Buffer Board (LJ41-02761A)

Based on the symptoms: It is possible that the Y-buffers are faulty, which may require the replacement of the Y-sus board as well. You may want to get a local technician to diagnose the unit and provide a second opinion.

Your board numbers should start with LJ92. They will cross to both Samsung and LG. Oh, your model number goes nowhere, double check it.

Hello
The power regulator PCB has some fault it it. It does not outs proper regulated voltages needed to the other PCBs in your TV. Normally Plasma TV power regulator PCBs are very difficult to repair, and PCB as whole should be replaced. If you give this set to Philips Authorised service center, they also will do this, and they too can do only this. In my opinion, it is best to get it repaired by Philips Service center, because, Plasma displays are very sensitive to static voltages, and repairing it without proper measuring instruments and circumstances, may damge it and it is irreparable. If fuse is gone out, you must aware that there must be som sort of short, or overload inside your TV circuits. If you have technical skill, a proper knoledge of the power regualtor working, and mor confidence and patience, you can do this. You have the ability to follow the schematic diagram of your set, which can be obtained from philips website. You must have a high quality digital multimeter, and static free DC soldering iron to go on. Some times, an Oscilloscope may also be needed.
Beware, your TV has built on most modern electronic technology, and is colstly one. Never attempt anymore on it, if you are fully aware of its working principles, and proper knoledge in Electronics. Philips uses some special components of their own, which cannot be purchased locally.
Determine yourself, what to do. OK.

SOURCE: We have a 50" Magnavox

My guess, as there is very limited information on your TV, is that you are in need of a new bulb. The problem is that it could be the bulb or the ballast that connects the bulb to the TV.

RED LIGHT BLINKS SEVEN TIMES


The most likely problem are two failed capacitors on the main board in the center of the TV The failed parts are easy to identify as the top of the cap will no longer be flat but will have bulged up. DO NOT attempt to remove the back of the TV unless you know what you are doing.
soldering on a circuit board will be required to fix this problem.

Magnavox 50" plasma Won't Power on/Shut's off/Blinking red LED


The above fix, listed by Tom saved us!! We did as instructed and took off the back of our 50 inch Magnavox plasma tv. We were not sure what we were looking for so we googled capacitator (image) & there was a photo of a fried capacitator! Sure enough we noticed ours were "fried", we took out the board and went to an electronic supply store, bought the 2 capacitators ($2.00 each!!) and then found someone who did tv repair to sauter the new capacitators onto the board. (It is important someone who know how to sauter and recognizes polarity do do this for you) All in all we fixed this following the above instructions for $34.00 and our time. For a month we were told to spend hundreds getting a new power board!
Kudos to you Tom & thanks so much!!

Red blinking light on a Magnavox Plasma TV


Here is the solution. For less that 100$ your Magnavox Plasma TV. Model # 50MF2310/37 will be running like a champ.

Issue:

Magnavox Plasma TV. Model # 50MF2310/37 screen has no picture. There is no sound, TV comes on and then after a few seconds clicks and screen remains blank.

Cause:

On the main power circuit board to Capacitors are prone to failure from over load. The caps are 3300uf 10v 105+c capacitors located to the left of the AC power input.

Service:

Magnavox will refer you to a service center. They will advise $$$ for an inspection. They will also want to charge upwards of 500$ to replace the entire board.

Solution:

1. Unplug your TV
2. Disconnect all connections from your TV
3. With assistance lay your TV on its face on a non-scratching service
4. Remove the back panel screws.
5. Lift back panel off
6. The central board is your main power board.
7. Remove all wire harnesses from the main board.
8. Remove all screws that are holding the main board in place.
9. Lift the main board out and carefully place it into a non electromagnetic pouch.
10. Take the board to a Circuit Board repair shop.
11. Have them replace the the above mentioned Caps.
12. Re-install the board in your TV.

NOTE: Replace the caps with 3300uf 16v 105+ high temp caps(preferrably Japanese caps)

This fix cost me 80$ and my time to search for other who had the same issue. Try searching for Magnavox Plasma TV. Model # 50MF2310/37 bad circuit board or Magnavox Plasma TV bad capacitors or Magnavox Plasma TV bad ciruit board.

Hope this all help, Magnavox is should take ownership for this problem and recall any tv's that have these caps in them. The worst part about this is that teh **** from the repair center that was paid 100$ to check the TV, stripped out the screw holes and damaged the case for the TV.

Portland Laptop Repair was awesome. They repaired the board and it looked like new. Check them out at http://www.laptopportland.com/

Magnavox Plasma HDTV Red light


I had a similar problem with my magnavox tv with the blinking light issue. Eventually it just didn't come one anymore. Looking at other forms they said the problem was a bad capacitor number 2074 located on the power supply board. When I opened my tv, I noticed that the capacitor was bulging and burnt up. I bought a new one labeled 2200uf 35v and did some solder to attach the new piece. Put the tv back together and it works like new. No more blinking light. I hope this helps.
