Hi,
Here is my problem: Samsung TV model: LN-T3256H When plugged in, red light comes on for 2-3 seconds, when goes dark for 5-6 seconds, then it cycles around. I opened the back pannel to look at it, I don’t have much experience with TVs or electronics, I generally stick to wiring battery banks/lights/house appliances There was quite some dust but apart from that, the only thing I could see was a blue round part marked DSC 5-15 that looked scorched. From a quick search I found it might be a thermistor? Could that be my problem? Thanks
Hi, Please verify the model number of the TV as searching online using the number that you posted produces no results? Here’s the No power troubleshooting flowchart from the service manual for a Samsung LNT3253H that may help. (model is as close as I could find) You need to check that the correct standby voltage gets from the power board to the mainboard OK and that it is steady. Looking at the flow chart it appears to be +5V DC. Hopefully it will be marked on the power board where it is. Look near the connector where the cable that connects the mainboard to the power board is connected. It will be designated something like STBY and a voltage value. Be safety aware when working in the back of a TV as there is exposed lethal AC voltage on the power board. Disconnect the power from the TV unless you need it for testing purposes Does the scorched part only show a DSC 5 -15 as I could only find DSC 5D-15 thermistors? Is it near to the mains supply input at all? Post a close up image of the power board. Here’s how to do this on ifixit Adding images to an existing question
