Im betting the vertical deflection is failing, a capacitor that is in the vertical deflection circuit may be dry and as it heats up shorts shutting the tv off.

    Tvs use a system of magnetic fields to deflect the electrons movement inside a tv tube. When the vertical delfection goes bad, usually a failed chip or a dry capacitor, the tv looses the ability to aim the electrons in the tube up or down. This will eventually be just a single straight line through the middle of the tube. Capacitors are mini batteries more or less, they have an electrolyte in them, when they get oldthis electrolyte dries out and the capacitor loose the abiliy to hold a charge. They eventually strt to leak current and short out or open effectivly killing the circuit. When they short its an overload and the tvs circuitry is designed to protect itself, it does this by shutting off if something is wrong.

Phillips 27ps55s121cc wont turn off w original remote or tv menu is this board level prob?

Yes, the entire main board used to be (you would have to ask Philips) available but we gave up (where I work) ordering them as too many were damaged or destroyed in shipping.

Board level repair:

check fuse
check power supply voltages
check for short to ground at horz. output transitor

We have an older Phillips Magnavox tv. The tv will turn on & we will see the picture for a short time but then the screen turns grey. We still have sound, just no picture. Also, the green power light...

Hello, the grey screen could be due to a missing 220Volt source which feeds the color (RBG cathodes)inside the CRT(picture tube). When this happens the beam current inside the CRT goes high in a matter of second, thus triggering the beam current protection circuit(blinking green light)shutting down the TV. Repairing the secondary voltage source is necessary to get the TV working normal, a good technician should be able to repair it for between 80 to 100 dollars parts included, except a picture tube, which could be also the cause of the problem(K-A shorts).

DVD input with signal access

IF I understand you correctly, the VCR, Satellite, etc is connected using an RF modulator/coaxial cable wire going into Antenna in

IF this is true, then you have an AV IN port (red, yellow, white) free on the back. Just connect the red, yellow, white from the out of the DVD - you can use 1 or 2 - just remember which one you used; and connect it to the AV IN on the back of the TV.

THEN press ch down on the TV remote until you get to "AV1" - it is below channel 2; double check DVD player to make DVD is playing and voila!

Need to know what's wrong with my tv

You may have filed this one in the wrong place. A maggie MS3652S is a 36" crt based model, with a L01.1UAC chassis. But you start off your explanation as if it were a projector TV. Check the model and series again and let me know if I can help...

Phillips 36" shuts off

It looks like that your TV is overheating. Most of the TV's have a fail safe so if any case they are over heating it will shut off so it doesn't damage the TV. i would advise that you seek help of a professional in your area.
