I've only had this TV for about seven months. The other day when I turned it on there was no sound. Do you have any idea what I should do to fix it?

Get a set of multi media speakers and connect them through the microphone plug in the back. I have mine set up this way and the sound is awesome. I purchased the Creative T-10. Can be found on ebay for around $15 + shipping.

Check the other sources first - AV, scart, hdmi, etc. If you get the same result your main AV board needs replacing or repairing.

I NEED A POWER SUPPLY AND CORD FOR A MAGNAVOX 15' LCD TV MODEL NUMBER 15MF400T/37 POWER RATING 12V 3.5A


Either you can get this universal type available inthe market in any electronic spares store or it is easy too make one by yourself if you are familiar with electroncis.
All you need is a mains transformer with secondary voltage at 12 volt and 4 amps capacity, use a bridge rectifier , good storage capacitor of about 4700mfd/25 volts and if possible use a 12 V regulator so that the power is smooth, regulated and protected..

IR reciever in my Magnavox 15MF400T/37 does not respond to the remote.


You basically have to take the tv apart backward to get to the front. Start with the back panel unscrew all the screws. Then you will see the internals. IR sensor should be botton left side if you looking down on it.

Philips magnavox tv model # 15mf400/37


no i havent a solution yet. am waiting to hear from Philips support & Customer Care by email or phone. I cannot afford to pay you people just to ask a question that i probably could not understand the answer anyway. I know my tv just stopped working and I think it was the manufacturers problem. Like i said it was not an old tv.

Cable for my manavox 15mf400t/37


The tuner and or the IF sections in the TV are going defective, or there is a power supply distribution fault that is effecting the TV's front end. One or both modules, or a board may need to be changed.

Take the set to the Philips authorized service to verfiy and fault and have an estimate.
