Sanyo dp52449-01 no picture, has sound, screen has faint brightness

The described may lead many to point to backlight inverters however it is extremely uncommon for backlight to work in a way that would produce "faint" light.

it is a whole lot more likely that backlight is functioning properly, but the display in front of it is all shut and not functioning, i.e. all light filters are closed and not opening.

This would point to either the T-CON board or the main board or, at worst, the LCD itself, which is however less likely.

May be something as simple as a bad connection of a cable on the LDVS cable - we've seen that happen once or twice.

Sanyo DP52449, tv getting power but no display

When DP52449 (chassis 01 - that is important!) does not power on and the front LED flashes every 15-20 seconds you have a faulty main board, which you need to replace or get serviced.

We presently do not offer replacement boards, but we do offer repair services for them at

You may also be curious to read the article we wrote back in July 2012 on a problem that sounds exactly like yours and which lead to the service offerring:

Hope this helps!
