Polaroid tlx-04230b blinking red light do not turn on

SOURCE: 42' polaroid tv wont show screen still

well if the light stays blue , that means its still on ...what you may need to do is go to your menue and select the setup selection and then go to tuning band.....i belive it will be on page 32 of you manual, under customising the setup settings....in order for the tv to start working it needs to be able to scan for channels.....if you are useing a cable company like comcast or direct tv...depending on how you pluged it into the tv ,(like using the input 1 or 2 , s-vidio, cable , ectra,)...you need to push the input button thats on the lower right side of your remote and select the propper input area as to how you hooked up your cable box

Yes I think that would be the problem, aswell as some dry (cracked solder joints). A bad cap is usually bulged on the top and looks like this:

I'm very appreciate to jranada's solution, my tv gets new life.
It's very simple to fix the problem to everyone.
My tv capacitor was not the problem.
I hope this will help everybody.

open the black plastic panel and the aluminum panel which has 3 screws each in the back of the tv.
look at bottom left corner of top board. to the right of the red led light,
there's these four white small switches. turn the bottom two switches to "on" and tv should be working.

you have a power supply problem.. I have fixed serveral tvs with this problem. normally you have to replace busted capacitors in the power supply board.
