Philips Magnavox 42MF521D/37 Television - Page 7 Questions & Answers
Will not come on if
A weak power supply is the signal I'm getting. One of the first concerns would be to find one or two bad capacitors as the culprit. Always, on the first level of repair is to consider bad caps. Thanks for asking and show a few hands of support!

you do not need to measure your model no. will tell you...42",

I have sound but no picture screen is black 19inch
I cannot say enough about this model. There is a bad capacitor or two in this set. You should be looking for a buldged cap at maybe 25 or 35 volts at 2200Mfs. Replace this and the next one near would be a 35 volt at 1200 Mfs. I have a question for you, if the model number is 42 MF, the screen is large. And yet you say it has a 19 inch screen. I'm not sure if you have the large TV or the small TV. The answer I give you is for the large screen. Hope this helps you! Thanks for asking and show a few hands of support!

Hi
Thanks for using FixYa. From what
you have described it seems the issue is with the power board or the main board
and we’ll need to check few things. When you open the unit up; take a look at
the power board-the board where the power cords/plugs goes into. You might see
some filter capacitors a little bulged up in the top-If this is the case-this
is your defective part(you can try to replace them-but some soldering equipment
is needed). If not, then probably the main board has gone bad. This is the other
board-where all the inputs are going into. All this is only recommended if you
have electrical expertise and know how to solder/re-solder components. Please
note that the TV components consists high voltages even when in off position. Please
do accept the solution if the issue is resolved or post a comment for further
assistance.
Thanks

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....
