The PS50700 uses the 195 series chassis. The most common cause of the set not starting up is a shorted flyback (high voltage) transformer. Sometimes a shorted flyback will also cause the horizontal output transistor to short too. These parts need to be tested and/or replaced by a tech familiar with the RCA 195 chassis.

TV won"t stay on turns off in 3 seconds WS 55807


Do the self check when power light goes off.

On front of set press and hold both the menu and input buttons for 5 seconds or longer and release both buttons.

Power light will blink a error code like: 2 blinks, 2 blinks, a pause and repeat about 4 more times.

Let me know what error code you find and I will tell you what it means.

If this information told you something rate this solution as very helpful as I do this here for free.

TV POWERS ON, THEN BACK OFF


I could be anything but mostly it will be its age, and if its never been cleaned out it could be the bulb failed, power board. dust build up can cause over heating of the parts. even damage them if the dust becomes damp. is there any lights flashing or any leds lite up ?

Setting up playstation


The PS50700 uses the PTK195 series chassis. You can switch the TV to the video mode by pressing MENU, press channel down 3 times to highlight "4 Channel", press MENU, press channel down twice to highlight "3 List and Labels", and then press MENU. The current channel will be highlighted, and you will press channel down until you go below channel 1, which is where the video inputs are (VID1, VID2, FRNT). To exit, press MENU, choose "Exit", press MENU and choose "Exit" again, or just wait until the menu times out. An easier way is to get a universal remote that has an "INPUT" button.
