Power Issues with Sanyo DP50749


Main board is most likely but that is an educated guess--problem with all these is you can only check so many things and then have to guess and try a board.

Hello my Sanyo dp42849 42 inch has no picture and no sound. when i turn on the tv a green light in the bottom right hand corner comes on and occasionally flashes off and then back on.


First, you need to know the sub-model of your TV.

It is called "chassis" and is shown on the back of the TV on the label where the model number is shown.

For example it can be "P42849-00" or "P42849-01".

Then search at www.coppelltvrepair.com/search or just go to www.coppelltvrepair.com and enter the link for SANYO DP SERIES to search for that.

Here's an example of a repair service (note it may NOT be the one for your exact model though!):

Hope this helps!

Hi.

I have problems locating the chassis number correspondent to this model number. I will need chassis number to locate service manual.
Please double check the model number and check if there is chassis written on service tag.

Here manuals for different Beko chassis.

Sanyo tv tuner identification


I have the sanyo part # 6450526084 . There is another number but could not find it online. There is a place called www.tiptoptuner.com that might sell you the tuner outright as they mostly rebuild them . The are the cheapest place i know of . You want to use the contact link and tell them the part # and see if they can cross it for you as i gave you part number. The ID # you refer to is on the tuner shield that you say is missing . Or you can google the part # to see what you can find should start with 1AV4FBAM???? . Good luck
