Volume keeps going down

If your source is the TV (RF input), then the Caption button on the original remote for the DP42841 will let you cycle through the available closed caption options. If you have a universal remote, you'll need to find a code that lets a Caption (or CC) button work with this TV. This is shown on page 8 of manual. ManualsLib has the manual here: https://www.manualslib.com/manual/148706/Sanyo-Dp42841.html .

If your source is any set-top box, you need to disable the captions on that source. This can depend on the system setup. I know that on one satellite dish receiver, the captions for a second TV on the system had to be enabled from the primary TV. (Then the captions showed on both TVs.) On a IPTV set-top box that I use, to disable the closed captions, I need to enter the Settings menu using a pass code from the provider. Then the setting is under Audio.

I hope this helps.

Assuming you are observing all ESD & Safety precautions...

The absolute best way to tell what pack you need is to LOOK at your old pack...

Go to a parts supplier...

Put in your make = SANYO

MODEL = something like "DP42841"

that ought to be a Sanyo Lcd tv ...

such as ... shopjimmy.com
ebay.com or amazon.com

Sanyo 1LG4B10Y04800 Power Supply

Look at the back or the side of the TV, you should have the standard buttons: power, menu, volume + volume - and input depending on the model, use the menu button to get to general menu and volume +/- to navigate

it has the sleep timer set

That sounds like a faulty LCD panel tab. The only true fix is to replace the screen. This usually isn't cost effective.

If brand new and have some issue or need something call customer service for this set--if missing something contact also the place where it was purchased.

Be sure your cable is hooked up good and if you did not auto scan you must do this (auto scan) Found in the menu setup. Use the remote and press menu and it is usually found easily. Highlight the auto scan and start the scan usually by pressing volume +

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!):
