Hello. I have a Magnavox 42MF531D/37B Flat Panel Television. My uncle gave it to me, because he says the power won't come on and i was wondering if that's a problem i can fix myself?


I would have to say probably not. If you have no power at all (no stand by light) then I would suspect a blown fuse , check plug , If you havestand by light nothing else i would think capacitors in power supply are leaky. Capacitors are cheap , easy to replace but not for a novice, Capacitors usually swell up when old and can easilly be spotted to the trained eye.
have your local tv guy estimate repair

Hello :i have a bad projection tv Symptom :power


sounds like my 32", its going to be one of three things,
Convergence board,
if it is this you will need to order one online and install it yourself, lots of guides online to help you with this process,
High voltage power supply,
again this can be purchased online and directions are available, if it is the high voltage supply, the tv will act like it wants to come one and maybe click a couple of times
Low voltage supply,
the tv will do nothing, now if the tv does nothing, the low voltage supply isn't the only possibility, but the most likely, check fuses on this one as they are easy

I have a wd52628


This area of the TV is a cause of some expense in rear projection.
The fan controls the temperature of the lamp. An obstruction keeps the fan from coming up to speed.
The power block controls the power the lamp uses. This helps keep the glass of the lamp from breaking breaking.
An arc is a badly mounted lamp or a lamp defect.
Dust build up can cause overheating.
Most of this area cannot be serviced by a non-technician.

Phillips/Mag Projection TV-9P5544C102 no pic/sound /pwr light on


John, my thoughts is something in the main power supply. I don't know what an opto chip is but I've heard of Optocupler IC's.
May be a good idea to give a call to some local TV Repair Shops especially ones that work on Philip's and see if you can speak with a tech to see what their thoughts are on what the problem is and what a repair cost may be.
The issue is one of hauling it to the TV shop or having them come out to you.
Blessings,

Hello repko,

This looks like a problem related to your High Voltage Protection circuit. This circuit shuts the TV down when it senses a high current condition (a short in a vital circuit). It may not involve extensive repairs, but it will involve some repair work. I can give you a better diagnosis if you do a few things for me.

1) unplug the TV and take the lower rear panel off
2) look at the back of the panel or in the TV for a chart showing you the diagnostic LEDs
3) Look at see if LED D912 is red or not (this may differ in your model, if so write down the numbers of all the diagnostic LEDs and there condition on or off red or green.
4)post these in a reply to this topic.

Once this is done I'll be able to give you some idea of how extensive this may be.

Thank you,

I hope this helps,
