My Olevia 527S11 LCD tv is not showing pictures and sound i noticeed one of the capacitor is bad ,how can i replace or trouble shoot.

SOURCE: screeching sound and display of color bars with no picture

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

I have had the same problem with my daughters Olevia...232-S13 out of the blue ti just decides to not turn on...blue light lit where the on/off button located but no sound and no picture....i guess the saying "you get what you pay for" stands clear here.......very upsetting.....

Try viewing the screen from a flat angle with some light source at the opposite angle while turned on. If you can see image 'ghosts,' then either the backlight fluorescent or the high voltage inverter for it has failed. This may not be cheap to repair but I wouldn't consider it a death notice.
If you or a tech finds which it is, you might try here for the board:
Jimmy's parts
These will be 'pulls' from mfr. overstock or disassembled sets. They do offer a warranty.
If the backlight has failed, I'm pretty sure a tech will know where to get them.

this sounds like a mainboard issue , a replacement mainboard will solve this problem
