My Samsung 32" LED TV Model CY-HF320BGLV1V made in Malaysia(SDMA)
While viewing news on my above TV yesterday its screen suddenly went blank/black & only red LED was glowing; since then when it is connected to AC mains only red led glows that too with a periodic short dips in its light at every few seconds. on/off switch not responding.
Supply Voltages are present on capacitors on P.Supply board but not present/reaching at 14-pins connector’s pins which is going/connecting to main board, but I am surprising n not able to understand how 3.3V is present on standby/ Red LED board.
Please guide to fix the problem. I am uploading few photos for your reference please.
Need Data Sheet of above IC

Hi,
What is the "board" number printed on the power board?
Can't see it too well in the pictures you posted.
Try searching online for the schematic for the board using the board number in the search term. With the schematic you should be able to find out why the Standby voltage is fluctuating
If no good maybe a replacement power board isn't that expensive to buy from a supplier that may have a good returns policy in case it didn't fix it.
