    This is the middle board of my tv.I am getting no power except the tv showing power and a click sound(relay)but,no power .Could my problem be the part with the red wires running to it?A few weeks before this happened,the tv turned itself off and then turned itself back on 2 times.It worked great the night before it stopped working.

Magnavox 51mp392h rear projection t.v's power button will blink continuous and there is a low chirping noise. T.V. does not turn on.

The chirping may be the key...When this is commonly the case its a convergence short. See more details on the site - Look for a chirping repair kit for your model. Its a common issue

My daughter kept pushing the on/off button on the tv. Now when I push the on button I don't see anything on the screen and I head a chirping noise. Nothing else happens. Help? Is this repairable or do I...

good day. maybe the power supply of your tv damage or fuse worn out. causing the on and off of your daughter. but it is repairable. you just need a qualified technician to fix your problem.

Philips rear projection tv-wont turn on

Sounds like your Convergence chips failed, were your red/blue/green colors slowly seperating or was the picture starting to curve on the top or bottom or both? if so see below general post.
Also what model # is your TV and what size?

Actually I have this TV and you need 2 Convergence IC's STK392-120's (120's and 150's will work) of course order 2 of the same type I'm using replacement 150's they allow for a little higher heat and were cheaper ALSO you need to replace the 12 resistors with 6.8 ohm metal film resistors, make sure they are metal film! don’t skimp out here I did and then they blew and fried my IC's and I had to replace everything again!

Great reference link that I posted pictures on, check out page 3

Where I got all my parts that worked:
Suburban Electronics

Manual Library you should find all you need here:

What you need:
(2) STK392-120 OR STK392-150 IC chips
(12) 6.8 Ohm Metal Film resistors
set of star screw drivers
15 watt pencil solder pencil, DO NOT use a high watt iron you will fry the surface mounted item.
good leaded solder, and flux

BTW if you don’t plan on trying this and are going to throw out the TV, I still need a IC convergence board for a 51MP392H/17 TV I'm fixing, I'm willing to pay S/H and buy your IC board that’s not been tampered with.

Philips Magnavox 51MP392H Rear Projection Television

are you getting sound, was it moved laterly, did you just get it from somone, did it get wet, does it make clicking noises, was the picture color/ convergence blurring before this, were the colors slowly seperating such as red/blue/green?, did the picture bow on top and bottom or sides prior to tihs, was there anything note worthy prior to the blank screen.

generally its IC convergence problem with the larger philips projection TV's however I need more info on your TV, also size make model # anything you can provide gets us a more narrowed solution.

hope this helps....

Mute and C on the screen

The TV is in factory or demo mode - turn tv off and unplug it from wall outlet for 30 seconds - turn tv back on after 30 seconds and see if problem goes away. If not, press the (volume -) and (channel -) buttons repeatedly for about 10 seconds to see if "C" will go away. If this fails call 1-888-PHILIPS for further assistance (they do Magnavox also).
