Question about Magnavox Televison & Video

Open Question

Magnavox 15MF227B/27 is very slow in assembling a picture upon start-up. Works well after several minute warm up.

No picture or a frozen picture is displayed. What's wrong and is it economically feasible to repair?

that set is highly rated by users .. it first came out in early 2009 (i think) so you might check to see if any warranty remains ... the display is illuminated by several lamps .. each lamp has its own high voltage inverter .. all the innverters are powered by an output of the low voltage power supply (often 18 volts)... i would suspect a problem with that low voltage power supply.. either a bad capacitor or a thermal issue .. .. ..

Magnavox 19" TV shuts itself off.....won't stay on


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Tv goes off after it warms up AND pic. goes SHORT and WIDE prior


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.

Delay to see the picture


Your power supply is going south, I have an old sony with the same problem. The voltage level drops and does not have enough 'kick' to start. It will work better when it is warm. The module will need to be replaced.
