Last week my Toshiba picture tube style TV wouldn't turn on.....but now it's on and I can't turn it off. New TV in my future?

You might have intermittent ON/OFF switch. Can't think of anything else according to the description of the fault.

Audio not working on proscan ps61700

I have a GE 46 in TV that had the same occurrence. I believe it is a sign that the amplifier is overheated or stressed. The way I fixed mine was to unplug TV and leave off for a few minutes -then plug in. I discovered this by accident when the power went off one day and the sound returned (had been using my vcr audio output plugged into my stereo for weeks!) This fix will work for weeks-sometimes months-evidently resets the circuits inside the amp somehow. Last time this happened I also removed the back of TV and blew out the dust with compressed air while it was unplugged-still have sound 4 months later without a "reset"-so I'm guessing it did help .

This may denote a proble in either your switching powers supply or your Horizontal section derived high voltage power supply. These are both very dangerous sections in your television. My next question is important; do you have a background in electronics? If not I would not advise you working on this problem yourself and that you take the TV to a repair shop for servicing. If you do have some background in electronics, I would like for you to make the following obeservations: What was the TV doing (it actions)prior to it going out? Did you hear any sounds before it went out like buzzing or crackling? What do you hear when you try to turn it on now, clicking? These questions are just to develop some background into what might be happening to your set. Thank you, Shuttle83

My tv looks dark weird

The original problem of turning off and on randomly could have been caused by a loose switch or contact in the front panel, or something similar like a short in the control circuitry. This might have also caused random features to become activated in the TV's menus; like the v-chip lockout feature, which is what you're describing now. I'm unable to find an online user's manual to see if there's a way to reset the v-chip lockout. Try a default password like 0000 or 1234, and if that doesn't work, see if you can find the user's manual (hopefully you kept it!) and look for instructions there on how to reset the v-chip feature or what the default password is.

One of the front control switches, that are located in the back of the buttons on the front of the set most likly are damaged or broken. These switchs are small and your going to need to pull out the entire chassis of the TV set to replair or replace them. If you have solid state TV repair experience thenm it should not be a big deal, but if you DONT please seek out a local tech to assist you with this repair as sliding out a TV printed circuit board can be a tricky thing, as it can bend ,crack or pop the surface mounted componets right off the board. A repair like this shouldnt cost alot. really all depends on if the board is damaged or not. good Luck

It definitely does not seem to be a problem with the Picture Tube. More like a cold solder. It is definitley not a job for a layman. Also, get a good technician to have a look, as locating cold solders is a labourous and time consuming process. It could also be possible that the main DC filter capacitor is getting dry, and may require replacement.
