Question about Philips 42MF130A 42 in. Plasma EDTV

1 Answer

Volume went to 100 and sporadically would keep trying to go higher. If I lowered the volume, it would go back up sooner or within a couple of minutes. Then the signal from the cable was interrupted then went black. Remote would not shut off TV only hitting the master off switch manually. Magnavox model 42 mf 130 A/37 Some posts say it's the power supply, other posts say don't bother fixing. Thanks for any advice

Do a reset to this TV, and then check. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts.

Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.
If a reset do not help, its main digital board is faulty.

SOURCE: magnavox tv trouble

Intermitant problems on old TV's are almost always poor solder connections. If you have done some soldering before you may be able to repair yourself, if not i wouldn't try to learn on this. Begin by gently tapping components on the circuit boards while the TV is on good chance you will tap an area and it will shut right off. make sure you are using something insulated and non-metalic. if you find a spot that is especially sensitive get to the bottom of that circuit board and begin soldering. this is probably the most likely cause but there are other possibilities. If you attempt this do be very carefull. My honest suggestion is to have a pro do it, if it just solder work it shouldnt cost that much maybe around a 100 to 150 if you can take it in somewhere.

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: Phillips 42FD9954 plasma will not turn ON

I have a Phillips 42FD9954/17S and every time I try to turn it on I also get the power red light blinking and sometimes it will try to turn on with a bunch of clicking noises and it will be green for a while then turn red. What I do and its very weird but works, put a blow dryer on hot and blow it under the tv on the side of the power button for about 10 minutes and it will turn on. I took it apart and there is a heat sink that if i put the blow dryer directly onto it on heat it turns on in less than a minute. Can someone tell me how I can fix this heat sink? I cant take it off. I want to put some thermal compound to see if that works. Give it a try I promise it will work. The Red Light has to be on put the heat on it and then press the power button, if you hear it clicking and green then back to red you are almost there. Keep putting heat on it and it will turn on.

Volume keeps going down


This is a problem with the sound select board, and there is no real solution. One thing to try is to press the manual volume up or down buttons on the side of the TV and keep them depressed to see of remote volume control is restored. This over rides the volume creep issue. I solved this by shorting the UP control to ground and the creep went away, but there is no manual volume control any more, but the remote still works.

Please have your power rating checked on the outlet and also if possible measure the mains voltage on the outlet . If low this can trip the microwave as it runs short of current/voltage.
Also make sure the plug is tight on the socket. Choose a lower wattage and see if the microwave works a longer time. If so the microwave must be checked within for a faulty capacitor, magnetron , wave guide or transformer.

Clean the oven , check the connections within and try once again before we can infer.

Distortion within a certain frequency range for wireless mics on magic sing 11000


Because of the very wide dynamic range of the human voice, specially when singing, the microphone you use, needs to be smart(usually expensive) to do the job properly. When going cordless, the electronics needs to be even smarter. A windscreen will not solve the problem.
I do not know of ANY low-cost radio mic that would not frustrate you for ever and a day. Rather spend a little more and be happy.
If allowed, I can introduce you to a very budget tipe entry level radio mic, that would work much better: Beyerdynamic OPUS 168 mk2 This mic works on a diversity UHF frequancy that receives a very clear signal for at least 100 feet. It also works with a "compander" , that improves the dynamic range. You will propably pay about $300 for it, but it will last lots of years with much less frustations. Sorry, there is no inexpensive way out on this one. PA Master
