Question about Akai PDP4294 42 in. EDTV-Ready Plasma Television
I have a 50" Magnavox Plasma (Model# 50MF231D/37). For the past few days it has been slow to bring up a picture. I'll get sound immediately but it would take a couple of minutes for the screen to "warm up". This morning, the TV will not turn on at all. I push the power button on the side of the TV, the light goes green like it's going to turn on and then the green light changes into a red light that blinks 4 times. I've gone onto the Magnavox website to troubleshoot my problem. They suggested I perform a software update. Well, I tried that and the TV goes into the blinking red light mode before the software update has a chance. I've owned the TV for about 1.5 yrs and I bought it from Wa-Mart for a steal because it was a display model. I'm sure that in itself creates it's own problems. I bought an extended warranty, but if it is a simple fix, I'd rather not send my TV out for lengthy repairs. The BCS National Title Game is next Thursday! :o) Thanks! Moriah
When you have the red light that blinks four times on the 50" Magnavox Plasma Model 50MF231D/37, you should look for the capacitors on the power board in the center of the of the TV. Look for two 3300uf, 10V, 105c capacitors that have a build up of pressure that has caused the top of the capacitor to look rounded instead of the flat top that will be on all of the other capacitors. Changing these two capacitors fixed the problem of the TV not coming on.
I had more trouble finding the capacitors than changing them. I could not find them locally so I went to an on-line electronics supply store where they were $1.65 each and $8.99 to ship.

Thanks to the guy that said to make the tent and use the hairdryer to warm it up in order to turn it on. For a temporary fix it worked perfect. As for buying the 3300uf, 10V, 105c capacitors I went to Ebay and bought 12 for $5. My husband and I also bought a soldering iron and soldering pump at Radioshack for about $18. We had never used a soldering iron but found it to be very easy. Removing all the screws from the back of the TV was more time consuming.

Where did you find the capacitors

Listen to the people who mentioned the capacitors....I bought some off of ebay...bought a soldering iron and pump at radio shack and just fixed my T V. As mentioned....the screws take forever to take out and put in...all together took me just under 2 hrs by myself. Desoldering and soldering were easy. Remove the circuit board screws to expose the side you need to desolder/solder new capacitors. DO NOT just rip the old capacitors off and make sure you have the right polarity when you put new ones back in.....positive and negative

Have 2 50" Magnavox plasmas same model. Fixed both for a few bucks. I can turn them on and off and on and off at leisure. No more blinking red LED.
The SW upgrade thats pretty commical when the TV won't turn on. Work on the sortware upgrade after you fix this. Never turning your tv off again is not a fix. I admit though I did this for 2 weeks and I wanted to strangle my sister for turning it off when she came to visit. LOL 1 year later I am viewing them again. I will send pics of what to look for and instructions...

Thanks to everyone that posted here. You saved me a lot of money. I have never soldered anything before and was a little apprehensive. I followed the advice above and much to my surprise, i did it. I did buy capacitors online that were a little larger in size than the original ones, I did this by accident but made them work. At the end of the day I spent 30.00 including a soldering gun, desoldering wick and capacitors. Careful on the size ( it definitely makes it harder to fit) and watch for positive and negative sides.

I found a bunch of videos on youtube for repairing the magnavox plasma. Here they are:
On the third link I actually found the exact part number for the capacitors. You can order them here like he did:
I hope this helps!

You have to make a tent for your tv and put some small heater inside (be careful), and bring the temp of your tv up and it will turn back on if you unplug it till the red lights stop, then plug it back in and wait for the green light to go out, when it does hit the power button on the remote. you should wait for the tv to be warm before you try and repeat till it works. then NEVER TURN IT OFF AGAIN! I have the same tv , and the problem gets worse if you turn the tv off ,all you will get is the red light

I can tell you 100% you have to capacitors that are bad they are on the power board side by side there 2200uf 10volt caps and i would suggest you upgrade them to 2200uf 25volt caps

Obviously having the same root problem, I ordered and changed the bulging capacitors. Did not solve the problem, as the problem is exactly the same.
I have found on Ebay the circut board LJ44-00118A.
Would this be considered the next cost-effective option to solving the problem before trashing the 50" (Model# 50MF231D/37) and buying new?
