samsung tv model ue55f6640 turns off and on the relay constantly
Thank you very much for answering, I have solved everything I have seen with ugly welds but the source remains the same connect some bulbs in series and continues to turn off and on the relay and the bulb of the series stays on bone that does not turn off and on along with the relay, so I think the source has some short.
ok we have short in the hot stage but I refer to this store where they sell the new power source at 39 euros and you get out of that headache since to find the fault go buy the spare parts if there is no wait for it to arrive, assemble it , ect ... a lot of time is wasted .........

Good morning, I replaced the source as you told me and the TV works perfectly.
Thank you very much to everyone for your help.
I found the ZQ851 in short, it is the STPS15L45C is a double shottky diode.
I have sent it to ask and when I have it and place I will take the measures that you tell me.
Thank you very much for answering.
Friend these diodes are very common in current TVs, you can look for one in the same position on a bone plate that has a run that is for TV of more than 42 ”and will serve you the same, you can even use one of those that use the sources pc for 12 volt. Greetings and luck
