Unplug it for about an hour to let it reset itself, if it is still not working, you will have to do some troubleshooting.

DP52449-01 power on green light OK , no control one ch. comes on and flashes on and off aboujt 10 times and then stays on with audio. still no control just on AND OFF CONTROL.


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

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.

We've also seen exactly that happen due to a problem on the main board, but the circumstances were such that it's hardly the same issue.

In any case , if you want the main board tested and possibly repaired you can use this:

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
http://www.coppelltvrepair.com/p/59/sanyo-dp52449-p52449-01-main-board-n7ke-repair-service


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:

Green status light keeps blinking after lamp replacement


continuous blinking green light indicates that the capacitors have failed on the DM pwb. You need the V26 DLP DM repair kit which is available at the following link under their repair category.
