12uF/100V Non-Polarized cap.

Hitachi TV, 46UX12B

Panasonic TV, TH42PX60U

Dead, 10 blink error code

Samsung Plasma TV, PN58B540

Reason for Service: 
Turns off intermittently, cycles

Solution: Use the melody to
guide your troubleshooting.
Does melody play when set turns off ?
No – means power loss, replace power
               supply.
Yes – means the set thinks it shut off
                 normally.  Look at 1 of 2 parts.

If the TV plays a melody, that means it could either be the mainboard or
the function/IR board. When you hear the relay turn on, quickly remove the AC
cord from the wall.  Now disconnect the
function/IR connector from the main board and replug the AC back into the
wall.  Does the set stay on ?

No –  main board bad.

Yes – function/IR board bad.
