    I have the same problem. When it first happened I turned the cieling fan on in reverse as to allow the air to sweep behind it. It didn't do it anymore for about two weeks. Than that didn't work anymore. A sevice man said it was the power supply. The cost of the repair was in the neighborhood of $1K. I declined the repairs and came here for help. What kind of voltages are you talking about? Is there a concern when the unit is unplugged? Is it possible that a relay overheating could be the problem? Please respond. Thank you.

    The problem you describe is on the pcb labeled "pkg-1720"
    the yellow transformer marked ec1180 in the lower center of the board
    about a $10 fix
    Just try to find one......not going to happen in this lifetime, I've been trying for a couple of weeks

This could be anything but is more than likely a problem in the power supply or control board. There really are not any user serviceable parts in these units and they have dangerous voltages. Repair is best left to a professional.

I have a sylvania flat screen 46 inch TV and will not turn on. It stays in standby mode. Any quick fix?


Do a hard reset to this set, and check. To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight; will be better. If it do not help you, check and replace the damaged component/s at its main board. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

Won't turn on led flashes green 8 time


Sounds stupid but I've had this issue with 2 different brand TV's and I unplug them for 5-10 minutes and then they are fine. I just had this happen just a week ago with a TV again.

Insignia 37" goes into standby mode


I am experimenting with Insignia's and there is a feature whereby if a signal is not detected the TV will switch to standby mode (in about 10 - 15 minutes). It's documented as a tiny "note" in the manual under "Understanding the basics - Turning TV on or off"

I don't know if the TV resumes when the signal is restored or if you need to power on manually.

You are probably experiencing a glitch with the signal or the TV thinking the signal is not there. Are you watching a clear picture when this happens? I would first check to see if the signal is too weak (like using a signal booster). If that is not the case, it's probably the TV acting up.

I hope this helps.

SRPD442 TV WILL NOT DISPLAY PICTURE AND WILL NOT SHUT OFF


This can be many types of faults. The set will need shop service. There may be cold solder connections on one or some of the boards, or there may be come components that are intermittant. In anycase most of the time, there will be the need for board replacments.

The cost for this type of repair can be fairly expensive. I would consider investing in to a new set because after having this serviced, there will still be many older components in the set that can potentialy fail.
