Question about Hisense TL1700 17 in. LCD Television
My TV just started turning off and on - light blinks from red to blue and back again. Initially the delay went from 2 minutes, 5 minutes, 15 mins and now today it took over 2 hours for it to finally turn on. I am not able to turn off the power once I turn it on initially and it is in the middle of it switch off/on ****.
I called my cable company and its nothing to do on their end.
Your problem involves 4 electrolytics on the power supply board. There are (3) 1000 mfd @25 volts and (1)220 mfd @16 volts. The power supply board is situated in the middle of the set slightly off to the right. It is held in with 4 screws and has 2 small harnesses on it. The 3 1000 mfd in the set that I was repairing were all swollen at the top and when I ran them on an esr meter sure enough they were opened. The 220 actually tested ok but was a little swollen at the bottem so I changed it anyway. After replacing all caps, normal operation was restored. Thanks, Jack from Staten Island
