Television and Home Theater

I know there are alot of people wondering why their tv's won't turn on, but so far i am unable to find any answers for myself. I have spent all day asking questions and trying to talk to people but no one will answer me back :-(

Hi guys i bought the model above but it dosent turn on or have any type of lights i took out the dm board and the capacitors do look puffy but i a also wondering why i dont have the green blinking light ( or any light for that matter) thanks guys ps i have hcn4226wx service manual if anyone want/needs it pm me.

Well, I finally got set up and made some measurements.  Thanks for your suggestions.....(See thread Sony 7 Blinks)

 1st....the tv will either come up (full operation), or it will click a couple times....no HV sound, and the LED will blink 6 times....indicating +5V problem 'Shutdown'.

+5 is fine at IC504...(except that pin number 4 is at 3.4V...is it floating?).  Case/heat sink seems to be at ground.

+5UNREG is at 6V.....that was the one I measured at Pin 8 of CN6504 (I think this is what you meant).
