If ordering a power supply board ,make sure that you order the exact matching number board ,requires removing the panel and writing the numbers down from old board ..there are at least 2 boards for the 42849 tv

The picture on my Sanyo DP42849 goes dark then brightens then goes dark again. You can still see the picture and hear sound.


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electro-medical.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

No picture ,but i hear the sound


Dim the lights, turn on the TV and shine a bright light on the screen. If you see a faint picture, you most likely have a failed back light circuit. On your particular set, I belive the back light and the power supply are on the same board. I'm almost certain that board needs to be replaced but have the board checked before replacing.

Sanyo DP42849 no picture but has sound


Sounds like an inverter problem. On some of these sets, the inverter and the power supply are on the same board. These boards tend to be quite pricey, $100 + range. I've worked on your particular model with the same problem, and it was a bad inverter/power supply board. I would recommend you get a diagnosis to be sure.

If sound stays on and doesn't goes off then you need the video logic main board, if the audio goes out, it maybe the power supply

I have a 1 year old sanyo 42" lcd tv, model DP42849, The tv was running perfect till one day watching a movie, the screen went black and audio went all strange, i shut it off and on, and nothing, the power...


You need to find out if the power supply is putting out 24vdc for the backlight inverter board, it can be that the inverter board has short circuits which will cause the 24vdc to go into shutdown to protect itself, you can disconnect the power cables to the inverter board to see if you will get the 24vdc back.

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!
