The plastic buttons are missing on the front display below the picture tube. Specifically the volume up and volume down plastic buttons have snapped off and there are holes where the buttons should be.
I've googled and I can't find what I am looking for.
Is there a replacement part for just this or do I have to purchase a larger part? Where would I purchase it?

Hello The fault is due to the microswitches on the front panel. Just replace all of them at the same time. These switches can be located just behind the front pane push buttons. To access it you have to open the TV, and take out the printed circuit board out.Pictures of two type of microswitches are given here. The shape may differ to tV to tv, but look this. may vary ins size and shape too.
I don't know if this can be done with a universal remote, but if you can let me know which brand and model of universal remote you are using, I will check if it is possible. If your universal remote has an "AV", "SOURCE" or "INPUT" button, try these but make sure the game system is switched on so you are able to see if/when you have changed to the correct mode.
If you don't have the original Symphonic remote, you should be able to switch the TV to game mode using the buttons on the front of the TV as follows:
1. Switch the game system on 2. Press the "MENU" button on the front of the TV 3. Highlight "PICTURE" using the CHANNELUP/DOWN buttons 4. Press the VOLUME UP button once to enter the PICTURE menu 5. Highlight "GAME MODE" using the CHANNELUP/DOWN buttons 6. Use the VOLUME UP/DOWN buttons to set "GAME MODE" to "ON" 7. Press "MENU" to exit the menu and play games.
The menu should automatically close anyway if you don't press any buttons for about 15 seconds.
When you have finished playing your game, repeat the above steps to set "GAME MODE" back to "OFF" and return to watching TV.
Hope this helps. Please post back for further assistance if needed.
The tv has been accidentally set for "demo mode". Press the volume up and volume down buttons in front of the TV at the same time for about 5 to 10 seconds untill the demo disappears or sometimes the TV will turn off. You should regain control of the TV after this.
if the tv width is ok try entering to service menu (do not use remote control) as follow: 1) turn the set on. 2) press the menu button and hold it down while pressing the power button. 3) while holding down the menu button release the power button and press the volume + button. 4) The screen will display a one line menu, on the left the parameter P00, and on the right the value of the parameter V00 5) release buttons. 6) using the volume + button change the right parameter until 76 7) using the channel down button change the left parameter until 06 (vertical size) 8) whith the volume + or volume - adjust the screen size. 9) when your tv is OK back to parameter 00 using the channel up button. 10) press menu button. and trouble solved.
The high voltage required by the CRT (picture tube) is missing. This circuit also produces the horizontal sweep that causes the trace to move from left to right and back again.
If you are still fortunate enough to have an old, honest TV tech in your area (we are dying out), this could be repaired for less than the replacement cost.
If you decide to replace the set, don't throw the Sanyo away, the neat new flat panels are dying like flies and you may want a backup set someday if you have the needed digital converter that will be necessary on all conventional sets at some point.
Stash the set in a dry place for eventual future use.
If you check with good light on the set-mounted buttons, you will probably find the nomenclature molded into the plastic.
Try bringing up the menu by holding both volume buttons down at the same time (or use menu button on remote if you have it). Go into CH SET using the channel and volume buttons on the front of set (or use the SET + and - and the ENTER buttons on remote). Go to the TV CATV line and move the arrow to CATV. Let menu time out. This will put tv into cable mode. Hope this helps.
It looks like one of the buttons on the front panel is stuck, base on the info you have provided; the volumen down button is stuck. The remote or any other buttons will not be operative until the fault has been remove.
I would suggest to try to press the Vol. down a few times just to see of it unlocks, if that does not work, the front panel assembly will have to be remove and try again if it works with the remote or manually.
The last thing to do if none of the above works, it will be to put a new switch.
