Question about Olevia LT37HVS 37 in. LCD HDTV
One day I turned the tv off, next day no power not even blue light. But red light in back of set lights up.....any ideas?
I had the same problem with a 437. It just shut off one day and I could never turn it back on again. I called Syntax Brillian and they told me the mother board was probably shot. They sent me a new TV and took the damaged one back.

Since you've already replaced the power cord and still the led light won't came on, this is an indication that the power supply board of your unit is dead. If it is not under warranty period(if so, avail it because the manufacturer will fix it for free) open the back cover and check the continuity of the fuse using the multimeter, if you found it open replaced it with the same current(ampere) ratings and then try to turn on the TV. If the replacement fuse blew again, this is an indication of more serious problem on that board. If the replacement fuse didn't resolve the issue, other parts on that board gone to malfunction as well. If this is the case, I would advice you to replaced the entire board for your convenient. The cost will almost the same rather than troubleshoot it. Check the actual part no of your board and check this LINK.
Hope I helped you.
Have a nice day!
Thanks for using fixya.

Same happened with my Olevia 540-B11. You can probably find the details of how to disassemble the TV somewhere online. The problem is poor stress-relief on the cables that plug into the secondary (low voltage) side of the power circuit board (PCB). Once the back is removed you'll find the PCB on the left side with three cables connected to the very top of the board. These cables plug into four clips, 3 horizontal clips side-by-side at the top and one vertical clip on the left side. Unplug these cables, remove the PCB and re-solder the sockets (there are approximately 40 solder points on the back of the board). Reassemble your TV and it'll work just fine.
