SOURCE: 50 inch plasma blank screen

I bought my Philips Magnavox 50" plasma in June of 2007. In february of 2009, I noticed increasingly longer delays in the video coming on after turning on the power and then the audio began to delay coming on. After a few weeks of this problem the audio and video then stopped coming on at all. However, there was power going to the unit because the green power light was working. I noticed over 50 other consumers on this website had the same problem. WITH THE HELP OF OTHERS ON THIS WEBSITE, I HAVE FIXED THE PROBLEM FOR $40. YES, FOR LESS THAN $100.00 I HAVE A WORKING HDTV AGAIN, BUT WITH NO THANKS TO PHILIPS - MAGNAVOX. THEY WERE USELESS. 

HERE IS THE FIX:

1. Unplug your power supply cord.
2. Remove back panel on your HD.
3. Look for capacitors that have a bubbled or slightly raised and rounded top. This indicates the capacitors have overheated or leaked and need to be replaced. The normal look is a flat surface with no raised features at all. (I had two bad capacitors that were side-by-side and identical: 3300uf 10v. Also, they should be located on the power supply board. My power supply board is in the middle of my 50" plasma.) 
4. Go to an electronics repair store or Radio Shack and see if they carry your capacitor type and size and replace them yourself if you are comfortable with removing the capacitors and soldering new ones to the power supply board. The capacitors will cost you $2.00 each or less. 
5. I was not comfortable replacing the capacitors myself so I removed the power supply board by removing the screws and unplugging several wire connections. This was not difficult at all. I then brought the power supply board to a local electronics shop that did repairs on HDTVs and simply asked them to remove the bad capacitors and solder two new capacitors onto the power supply board. They did it for $40, which included cost for the 2 new capacitors, while I waited and it only took about 10 minutes.
6. I replaced the power supply board and back panel of TV and it worked!!!

Some people on this sight suggested replacing the capacitors with some that have higher temperature ratings. Based on that advice, I wanted to replace my two that were bad (3300uf 10v) with two rated at 4700uf 35v, but my electronics guy suggested against it. Instead, I replaced mine with 3300uf 50v, with the only difference from the original parts being the higher voltage (50v instead of 10v). I figure if the problem occurs again, I now know I can get it fixed for less than $50.00. Philips - Magnavox should be ashamed for such poor customer service and not telling people about this simple fix. When I called their customer service support number I was simply directed to a repair place --over two hours away!!!

How do i fix my lg plasma tv that has screen filled with multi collored vertical lines abd screen showint three bands of color green, light green and purple?


If you have to ask this, I assume you don't have the kills to repair a plasma TV. Then please don't start this. Opening it can be very dangerous, and without the technical skills, you even don't know where to look for. Most to the time I advice to visit ifixit, but this time they don't have the manual or video for LG. Perhaps they can show you some openings. But they never show you how to rebuild.
They can help with spare parts. So if you really want to do this yourself. On your own risk:

Reset button


Most likely it's a capacitor fault. This is not something you press a button to reset. A think is broken inside the TV. It needs to be replaced to make the TV work again.

Google "Capacitor bulge" and then search Youtube for your make and model to see if anyone has done an instructional video. You'll need to be comfortable dismantling the unit and be able to use a soldering iron. If this isn't you then take it to a repair shop.

I have had my Philips Flat screen Plasma 42inch TV for about 4 years now and all of a sudden the TV screen will not come on all the tv is showing is the green light flickering and the sound comes through...


Yes, this is caused by a capacitor problem, take the tv apart and on the main PSU board the faulty capacitors will be evident by their bulged appearance. Andrew Eve

Plasma wnt stay on


I have had this problem in some models of plasma sets before. In most cases the power supply and main drive boards had to be replaced. In a small number of cases the failure was the screen itself.

In all cases, the cost of the repair was expensive. For the screen failure, the set was scrapped.

Inability to turn on plasma screen


You have a power supply fault or one of the drive boards that drive the plasma screen is loading down the power supply. This power supply may be part of the entire main board. Good Luck
