SOURCE: does not turn on

The problem:Press the power button and the led turns blue, but nothing happens. I figured out that if i unplug the set then plug it back in it worked. We did that for about 2 weeks. Then one day nothing, no matter how long I left it unplugged.

My tv is 18mos. old out of warranty and Polaroid refuses to do anything about. I am extremely upset because I know that this is a manufacturing defect.
This may or may not work for other Polaroid models I have no idea. Here is a picture of my info.

Anyway here is how i fixed my set.
Total parts cost $5.12 

This has worked for me, I am no technician so I can't say that it will work for you. Click here for information on caps. Or here
If you try this it is at your own risk! 
Defective Parts:2 CapXon 1000uf 10v caps.
Replaced Parts:2 Off brand 1000uf 16v caps. (the closest match my local supplier had.)
Once unplugged and flipped over I removed these three screws to access the control box.

Carefully pry up and pull back on the vented cover. e857ee8.jpg 
With the cover off I removed 3 more screws and again carefully pryed up on the control box cover to expose the inside.
4f3d408.jpg Circled is the location of the bad caps. (This is an after picture. I didn't take any pictures of the caps still on the board.)
Press your index finger over the tops of the 2 caps and feel for a bulge. Good caps should be sunken in. Bad caps ballooned.

1822746.jpg In order to de-solder your caps you must unplug all connectors and remove the 4 screws holding down the board. Be very careful!, and only touch the sides of the board. Wear an anti-static band also.

1b2e11a.jpg Once removed pull of the plastic shield underneath the board. Be careful and save it, YOU MUST PUT IT BACK.
Carefully de-solder the old caps. Replace with new caps. 
Note the polarity This is very important! On the board look for the + sign. That is your positive. The longer lead should go here. Take your time and verify This step.
CLICK HERE FOR CAPACITOR POLARITY

(sorry no pics on the cap removal and install I wasn't positive that this would work so I didn't think about taking any.)

Reverse the procedure to put your set back together.
Now plug it up and hope it works for another year! 
Curse Polaroid and vow to never buy anything from them again!
