Make sure the video input is properly selected with where you have it plugged in

Make sure that the video cable is connected to the same input that the audio is connected to. (ex. video 1 input matched to audio 1 input) If not that I would replace the video cable.

I have the same problem the tech told me that the picture tube is bad and costly to repair or perhaps not

Hitachi 65S700... • Answered on Jan 09, 2010

software change all the time. If you want everything to work properly you need to keep it up to date. Programs may stop working or freeze up if they are not in sync. It is up to you, but it is a good Idea.

It is probably a convergence problem which would involve solder work to change convergence i.c.s or if there are not colored shadows around everything it could be a problem with tubes. On a few of these I was able to remove the front grill and take off the small door, and with an insulated screwdriver gently tap on the neck of the tubes with the set on. Now if the picture flickers you have some particles on the filaments of the tubes and sometimes the debris will break free when you perform this, allowing your picture to restore full color and brightness without changing any parts whatsoever. Otherwise, the convergence chips are located on a large metal heatsink and have a generic part number printed on the front of each. Sometimes you have to remove a pressure clip to see it. Hope this helps, Russmann.

first thing is unplug the set from the wall for 10 min.
Check also carefully to see if one of the buttons on the tv is stuck in the on position.
or if cleanig solution was used on the screen and it ran down onto the switches. if so spray WD40 on them.it will not harm your tv.
Last option is a bad EEPROM.

You have a convergence problem
If the set has auto focus and will not complete its cycle.
The Auto focus module is bad, (expensive)
If it completes and the problem is still there.
Then check for bad conv. drivers (stk****) or cold solder joint on one or more of the 3 drivers pins.

This is a 15 k frequency sound
It is usually caused by one or more of the components in the High voltage circut,
with the set on and the back off, take pencil with an eracer.
Then push on each of the coils or transformers to see if it stops or diminishes.
if so coat the part with silicone sealer spreading to at least 2 components nearby. let dry.
This may help.
Thanks guy9

check for loose plugs or bad solder joints on the main circut board.
Espescially on the vertical output I.C.
Thanks guy9

Okay, I'll try. First, unplug the set for 2 minutes and retry. If you have on-screen-display when this happens, try another input and a different set of patch cables to eliminate any simple problems. Then remove rear cover and peek through to see if tubes are lighting and listen for current to the tubes. There are usually small green and red lamps on the board which will flash upon failure in the set. These are there to direct us to the failed circuit. That should get you started. Good luck, Russmann.

Oh so it is a used TV set. You may have the leaking CRT coolant dripping onto the printed circuit boards and shorting them out. Have you tried the video inputs yet? If those are bad as well, the DM-1 board could be bad. There really is no definite thing that could cause this I'm afraid. Have the set checked out be a trained tech. Good Luck

Try resetting the power by switching off the TV and then switch off the TV's power outlet and disconnect the TV's power cable from the outlet. Press and hold the TV's Power button for about 30 seconds to drain any residual power from the TV and then release the button. Turn on the TV in the normal manner and see if it turns on then afterwards.

If it works, put it on Facebook MarketPlace, free to collector. If it doesn't, you might be able to split it in the middle. https://www.cnet.com/reviews/hitachi-51swx20b-review/ ..
