Question about Sanyo DP32648 32 in. LCD TV

1 Answer

The TV shows no indication of a working power supply. The LED on the front panel does not light. The fuse on the PS is good. It's conceivable that the PS is good and the mainboard is bad, Is there anything I can test for (e.g voltages at the PS) or look for (e.g. board mounted LED) to identify the problem board? Thank you, Bob

Hi Jonathan,

Yes, if there's no LED light at the front panel of the TV, this is an indication that the power supply is not working (I'm assuming that you've already tried to plugged it in to other working outlet). First thing to check is the internal fuse of the TV. If you found it open, replaced it with same current(ampere) rating and try to power it on again. If the new fuse blow again this is an indication of more serious problem in the power supply. You may replaced it with a new board or seek for an assistance of a qualified TV technician to troubleshoot the board.
If you found the fuse intact, still the same problem(power supply board).
Please let me know if you need further assistance.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.
