I hope it is still under warranty!
Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

SOURCE: Sanyo 46" lcd had half

There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance.

The best way to check for loose connections is to tap lightly when the set is powered on , If there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points.

Since this fault occurs when the set warms up, if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault.

Based on the above method you must be able to locate the area of fault and solder the sections. Sometimes large IC's- ones with more pins- tend to have drying in some pins and so cause faults related to the IC's protocol. Have a rough idea of looking into the areas to reduce the time of probing.

SOURCE: fuse location for a 50" sanyo tv

The fuse should be located on the power supply board. You'll have to remove the back cover to access it. I posted a link of what the board should look like.

My sanyo dp46841 stopped receiving analog signal. Any suggestions?


I guess there are no longer analog signals worldwide. Try to connect cable tv to video input of tv.

My 46" sanyo lcd tv screen was all black on the right side and got to where it shut off now it wont even come on


Specifying the model - and in case of Sanyo TVs the chasis - is critical for faster and proper diagnostics of such problems.

Here are a few points of reference, neither of which covers nearly completely the very wide Sanyo TVs line:

46RV535U 46 in. HDTV LCD TV where is the fuse


There are several fuses on the power supply board.

Usually the one that fails is not the main AC line fuse (which is close to the AC line input), but the PFC fuse located, you guessed it, next to the PFC regulator IC on the board.

When the PFC fuse is blown (measuring open) you also need to replace the PFC IC and possibly other components on the board. Most of the time the PFC is sufficient though.

Here's a link for repair service for the board:

Also search there for the TV model, we may have repair kits or exchange services available!

Hope this helps!

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.

Need a remote code my new sanyo tv to go with att-uverse cable sanyo #dp19649


I went through all the Sanyo TV codes and then started entering in groups of 10. The U-verse offered 1103 i did 1100 to 1110 and it worked with 1107. Unfortunately at&T said you have to check the manufacturer which doesn't list universal codes. I was lucky on the Sanyo 18.5" LCD from Walmart using 1107!
