This problem seems like a defective or leaking zenerdiode in the receiver section. the receiver uses a 32volt zenerdiode that holds the voltage steady at the desired peak. when this is defective its voltage trought this part goes all the way up. especially when changing channels. according the self protection, the tv unit will shutdown when passing the 32 volt.<br /> what you can do is lokate and change this zenerdiode or change the receiver board. i think the last one will be easy if your not handy enough. succes and enjoy :)

Try this: Turn off power and unplug the set and disconnect any peripherals from the set. Hold in the power button for at least 60seconds, then reconnect the power and try it. It may reset, no guarantee though.

We have a similar problem when changing channels/surfing, the TV will begin to power cycle, until you unplug THE CABLE TV input, then it will turn on again and stay on as you rehook the cable and change channels....till it decides to do it again, DTV channels seem to trip it up, but not sure....if I leave it on the same channel it will run for days. Yep and the cable TV is grounded outside

There is sound but no picture and there is no response when using the control buttons on side of tv or the remote. I turn the tv on and change channels thru Comcast cable.


Talked to a Westinghouse tech and told to unplug for about 3-5 minutes, then re-plug. It's like having to re-boot your computer when it goes down or starts acting wacky. It worked, I got picture. Says it could happen again, maybe 1-2 times a year is o.k., if it starts to happen every few weeks, then it's something more.

50" philips won't power on. get the 4x red blink led light


i have fixed 3 of this tv, with that exact problem in the last 2 weeks, needs a power supply, you can try to unplug it again, plug it in, hit the power button, as soon as it turns green, unplug it again, after 15 seconds , plug it back in, if power doesnt turn on by itself, turn it on, if it turns red again, emediatily hit power again, may have to hit power a few times in a row, but most of the time you can get it to come on this way, once it is on, it should run ok, until you turn it back off, but not a fix, needs power board

Black TV Screen above Channel 46


Try resoldering the tuner can's connections to the main board.
If that doesn't solve it, you need a new tuner.

Or do what all too many people do, use the VCR's tuner and just leave the TV as a monitor.

Sony kv-32s42 needs help.Tuner problems?


Hi Grasshoppa, I would venture a guess that your tuner is not at fault but most probably the logic circuits controlling it since as you posted, you can tune > get a good picture but "channel numbers in the upper right hand corner ...." If your intention is to use the VCR and thereafter change channel using the VCR, you may use the Audio/Video input. With an RCA 3 cable connector, connect the (Yellow) Video out, (Red/White) L/R Audio out of the VCR to the Video in &L/R Audio in of the TV. You don't need to set the TV to Ch 3 but rather select Video 1 or 2 or A/V. Hope this be of some help/idea to you. Post back how things are or should you need further information. Good luck and kind regards
