It is two 1000uf 10 volt capacitors on the power board. the tops of the
capacitors will look like they are bulging. total cost of parts around
five dollars. if you can use a soldering iron and have a half hour to
spare this will fix it .there are alot of polaroid customers that have had
this problem and fixed it themselves. just click on the follwing to see
the video on this fix http://www.youtube.com/watch?v=unuS3CvmWtw

It probably is a capacitor or two. You should let a good TV Tech give you an estimate.

High pitch screech w/no signal


is this a picture tube type of tv? big in back? If so, it could be the tube/circuit short.

If it flatpanel, it could be a bad capacitor in the DM or "Y" board or even possibly faulty power supply. Further testing will be necessary
