Question about Samsung SPN4235 42 in. Plasma HDTV
When watching TV the screen went black never to return again. The red light flashes 5 times when first powered on. Any idea what might have went wrong?
SOMETHING IS LOADING DOWN THE POWER SUPPLY...COULD BE THE Y-SUS BOARD OR UPPER OR LOWER Y-DRIVE BUFFERS...TAKE THE BACK OFF SET..GIVE IT THE SMELL TEST AND EYEBALL THE FLAT I.C.`S ON THE THIN BOARDS TO THE LEFT OF Y-SUS BD. IF NO BURNING SMELL AND NO CRACKS ON THE FLAT I.C.`S ...TRY REPLACING THE Y-SUS BOARD...NUMBER ONE PRIME SUSPECT...DO NOT POWER UP SET WITH BACK OFF UNLESS YOU ARE QUALIFIED SERVICE TECH...JOE ACE
