If its production date is more than four years retire it, to answer your question the set will have two single or one large boards, the two board version one of the boards drives the picture on one side of screen and other on the other side, the version with just one larger board combines both boards into one

You might want to Google the model number with"parts" to see what is available and at what cost for this set, They only sell boards and no individual parts for all of this type of set.

An earlier post of the smaller model of this with the same problem said to remove the metal cover over the power supply.

I have the 26MF231D and it worked great afterward (even though you can't mount it)

Here is how you remove the cover.

SOURCE: Picture Size

Keep in mind that not all programs and show are in widescreen format. When set to normal, you will get those black bars on the sides because the program is sized for the older TV's. Some TV's will have a zoom option, but that will cut off some of the top and the bottom of your picture.

Until everything goes widescreen, you are stuck in normal with those black bars or widescreen with the fat people.

I hate distortion in my TV image, so I am perfectly fine with my TV on normal.

Good luck.

I had something similar shortly after I bought mine, my 11 year old walked over to the set and used the on-board power button, telling me everytime we lost power he has turned it on there before the remote could do it. At least it is worth a try....

I had a similar problem with my 42 in Philips LCD HDTV.


Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.


1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)


2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found at tv-part.com but supplies are limited. I would definitely shop around though.


3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.


This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's called: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.


Hope this helps and if it does please rate it accordingly. Good luck.

My magnavox model# 42mf230a/37 tv turns on I get good sound and picture but it has a 4inc black line onleft side edge of screen


Black lines on Plasma TV are cause by either the buffer boards or the logic board. OR your screen is bad. the only way to find out is the replace the boards. I would start with the Buffer boards. The buffer boards are located on the bottom of the screen attached by ribbon cables to the screen. look at the bar and replace the board that lines up with it. You can find parts fro this TV at www.interliquidparts.com You have to get the actual part number from the part on your TV to get the correct one.

Vertical black line on the screen of my 42" Magnavox flat panel lcd tv


I wish I could post a solution, but I don't have one. I too have a Magnavox. About 6 months ago, once every 2 weeks or so, the screen would just go black- all but an inch or two on either side. Now, it seems like it's a weekly thing, sometimes every hour or two. As of tonight, it has happened twice in a matter of thirty minutes. It usually repairs itself if I turn it on and then off again but that's just not working anymore. If anyone has a solution, let me know.
