    4 blinks in your Philips Plasma TV mean that the
    power supply unit has gone bad and should be checked. You’ll need to check the
    power supply unit for swollen/bulged capacitors and replace the one that has
    gone bad. Please do accept the solution if the issue is resolved or post a
    comment for further assistance.









    Thanks

Red blinking light on a Magnavox Plasma TV


Here is the solution. For less that 100$ your Magnavox Plasma TV. Model # 50MF2310/37 will be running like a champ.

Issue:

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.

Cause:

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.

Service:

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.

Solution:

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 TV.

Portland Laptop Repair was awesome. They repaired the board and it looked like new. Check them out at http://www.laptopportland.com/

I don't know why but this got my TV on.
I took off the back cover and found the source of the clicking.
Two blue plastic rectangular relays in the exact middle.
When I pushed the power button, I felt the top relay click, and I saw a flash from the bottom one. (they are right next to each other)
I took a hair dryer and placed it over the two relays for about 1 minute and tried the power.
It clicked only 4 times and then came on!!!!!!!!!
For some reason heat helps the relay.
If anyone is a tech and can explain this, please do.
Good luck!!!!
My tv is on and it didn't cost me anything.
I just can't turn it off now!!!
