The power light flashes off & on, the screen blinks off & on. takes a long time to come on. we unplug the tv & push the buttons & finally it will come on . everything works fine after it comes on.
the last two days i have used the hair dryer through the vents to heat it up & it seems to come on sooner than without doing this.
any heelp would bee appreciated.

Re: magnavox 37mf32id/37 hd tv
It looks like there might be some dry/cold solder joints in the TV circuitry.
I would suggest to check those solder joints, specially around high power resistors in the power supply area using a inspection tool such as a magnifier with power magnification of 2X to 4X.

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
If blinks continue without any pause, the main board is faulty.
I have the exact same problem! I have it hooked up to a power strip now to unplug it by flicking of the power strip and waiting for the red light to go out then I turn it back on while Channeling up 10 X's and then down and up until it comes on. I listen to the sound of the switch which it comes on. I turn it off if it is faint and then back on and channel up. Crazy process but it's been working. It takes about 10 minutes everytime to get the TV on until I get a tech to come out and look at it. The capacitor keeps a charge which is why the light is flashing with a code for 60 seconds./JJ
Here is the solution. For less that 100$ your Magnavox Plasma TV. Model # 50MF2310/37 will be running like a champ.
Magnavox Plasma TV. Model # 50MF2310/37 screen has no picture.
There is no sound, TV comes on and then after a few seconds clicks and
screen remains blank.
On the main power circuit board to Capacitors are prone to failure from
over load. The caps are 3300uf 10v 105+c capacitors located to the left
of the AC power input.
Magnavox will refer you to a service center. They will advise $$$ for
an inspection. They will also want to charge upwards of 500$ to replace
the entire board.
1. Unplug your TV
2. Disconnect all connections from your TV
3. With assistance lay your TV on its face on a non-scratching service
4. Remove the back panel screws.
5. Lift back panel off
6. The central board is your main power board.
7. Remove all wire harnesses from the main board.
8. Remove all screws that are holding the main board in place.
9. Lift the main board out and carefully place it into a non electromagnetic pouch.
10. Take the board to a Circuit Board repair shop.
11. Have them replace the the above mentioned Caps.
12. Re-install the board in your TV.
NOTE: Replace the caps with 3300uf 16v 105+ high temp caps(preferrably Japanese caps)
This fix cost me 80$ and my time to search for other who had the same issue. Try searching for Magnavox Plasma TV. Model # 50MF2310/37 bad circuit board or Magnavox Plasma TV bad capacitors or Magnavox Plasma TV bad ciruit board.
Hope this all help, Magnavox is should take ownership for this problem
and recall any tv's that have these caps in them. The worst part about
this is that teh **** from the repair center that was paid 100$ to
check the TV, stripped out the screw holes and damaged the case for the
Portland Laptop Repair was awesome. They repaired the board and it
looked like new. Check them out at http://www.laptopportland.com/
