This is a common problem with Sanyo televisions. This is a faulty main board and it gets even worse. Sanyo does not use a standard main board in their models. You will need to look at the main board (this is where your HDMI cables plug in) at the bottom there should be a part number such as N7AJ. Shop Jimmy is probably the best place to find the part; however, you will likely be waiting a few months because this is such a HUGE problem with Sanyo televisions that no-one can keep the parts in stock. This happened to my 46 inch DP46819 model and it took almost 5 months to get the part, which did fix the problem. This all started suddenly, one day the television was fine, the next there was no sound or picture and just a green light on the front of the set that also went out after about 15 minutes. I searched everywhere for the part and found nothing. When researching the problem there are LITERALLY hundreds of thousands of this exact same complaint for these Sanyo televisions. Like I said it took 5 months to get the part from Shop Jimmy (shopjimmy.com) but I finally did get the television fixed. I have since bought a Vizio and given the Sanjunk to my grandkids to play video games on.

SOURCE: My Sanyo DP46848 LCD TV display goes black when turned on.

My mother's was doing the same thing (purchased 2008). Put up with it about 6 months and took it to a repair shop. Bottom line - the display panel has a flaw in and will cost more to replace than the tv cost. See about it now it yours is still under warranty.

hi,doe sthe screen of your TV lights up?during power on?if not then there might be a problem on the inverter board and the backlight lamp of the monitor .The lamp is a cold cathode bulb it requires a high voltage supply from the inverter board in order to light up.just like any other bulb this lamp has a limited life span more or less 2 years of continues lit.The inverter board is a high voltage board the power input of this board is 24volts DC and the output is 200volts AC.The terminal input of this board or connectors must be check because of high voltage corrosion and loose connections always happen that leads to the mal function of the display or screen failure just like what happen to your TV.
Backlight lamp is installed at the top and bottom of the screen you need to open the back cover of your TV to check up the lamp.(make sure to unplug the TV before proceeding)..check first the test point that I mentioned then post back for your findings then will proceed to further trouble shooting...GOOD LUCK!

I have a sanyo tv model # DP46848. one half of the sreen stays dark until it seems to warm up. it is taking longer to warm up now. is it repairable and what part would I be looking for. thank you


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://electronicshelponline.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.

I have a sanyo dp46848 TV that turned off and won't turn on. There's no lights, sound nothing. What happened


Did you have a power surge or the lights went out? Many times this will cause the switching power supply to fail. Very easy to change out. If you are good with electronic you can take a shot at replacing blown parts, mainly electrolytic caps or maybe burned diodes. Contact Jimmys tv repair if in USA. They carry almost all parts.

You have a defective LCD panel tab connection. The only permanent fix is to replace the panel. A replacement panel will cost more than a new set. I had the same problem with the exact same set.
