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.

SOURCE: I have a SANYO DP46848,

This is likely a problem with your TCON circuit board inside the back of the tv.

The TCon board usually has 2 (or 4) very thin ribbon like cables running from connectors on the board to the actual LCD screen panel. Each ribbon controls one half (or one quarter) of the screen. If you are lucky, it's possible one of the ribbons came loose or is not making proper electrical contact with the connector on the TCON board.

If your tv is out of warranty and you are comfortable working safely with electronics then you may be able to repair this yourself with a few hours of screwdriver work. The ribbons may just need to be reseated in the little flip up connectors, or you may have to clean the copper at the tips of the ribbons gently with a pencil eraser to remove any oxidation.

If you are unlucky enough to have a bad TCON board or are not comfortable disassembling your tv yourself then you can bring it in to the shop and they can probably repair it for less than $150.

Good luck and please post back with how you make out.

No boards in those models interchange with each other. Totally different.

SOURCE: i have a sanyo 46" lcd hdtv model #dp46848. its

Solved: Over the course of time, the cheap plastic frame and stand starts to put uneven pressure on the LCD causing it to malfunction. I guessing this could be heat related. Definitely a design flaw. Remove the bottom of the stand and very slightly loosed the small screws around the back of the frame allowing the LCD to have some wiggle room. After I did this, it worked. It will still misbehave if you stress the LCD, but normally, it shouldn't. I am going to try to mount the TV using the rear VESA mounts & see if it will still work.

Why does my sanyo dp46848 screen go dark but whites are too bright?

First try to gently push the cable between the main board and the LCD controller (T-CON) board and if that doesn't affect the image then replace the T-con board.

Sanyo 46 IN. tv DP46848. The left 1/3 of screen is dark

It is a common problem for this model of a Sanyo TV, it uses a Samsung or Chime LCD panel.

The problem is the data buffer IC soldered on the flat flex cable between the LCD panel & the buffer board that gets damaged or loose soldering. If you be able to fix yourself, you may find some videos on YouTube, it will show you how to fix the buffer problem.

I have a Sanyo 46 inch flat screen hdtv purchased from walmart aug. 31rst, 2008. Sure enough, 13 months later my tv is having picture problems and getting worse. It started having portions of the screen...

I have the same problem, my television is faded black on the left side with lines on the left top side. I have had the 46 inch unit for 1 year and 7 months. I am planning to write a demand letter to Sanyo and then taking them to small claims court woth evidence that this is a common problem with their units that they know about and is not trying to remedy. Also the Attorney general in Texas should have an interest in them (Walmart and Sanyo) selling these defective proucts in the state.
