    I have almost the same problem I have no picture whatsoever, there is sound but nothing shows, thanks to solution #1, but I don't know where these areas are. Could you be more specific? Are they on the back of the tv? How do I check it to see if it is this?

On the power supply module there will be three 1000uf caps at 15vdc and one 47uf at 50vdc change them to 25 vdc and 100 vdc respectivley. The location number is differant depending on the size of the display but they are easily identified. This will fix 8 out of 10 Polaroid's 32 to 37 inches.

Hello dougie49

I would first check the back-light and the inverter. usually these are what causes the problems in LCD displays. If the inverter is bad most likely the back-light will have problems. If you need to replace the back-light 9 time out of 10 you will require a new display element.

I hope this helps

Thank you,

You need to check your inputs. Make sure your tv is set to the same input that you are plugged into. Ex. If you are plugged into HDMI 1 then your TV SOURCE needs to be on HDMI 1.

It is worth fixing but you have to replace the power supply. It is a fairly common problem with the Westinghouse units.
