Black TV Screen above Channel 46

After my TV has been on for a couple of hours all channels 47-125 black-out. If I unplug the set or simply leave it off for a couple of hours they come back - only to disappear after running for awhilelonger. I switched the cable input from Ant 1 to Ant 2 and this seemed to solve the problem for about three weeks - but am back to this on/again - off/again routine. The lower channels are unaffected.

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.

Screen goes black we change the channel to 3 and leave for sometime then eventually we can change back to video 1.

Hi jettabishop,my name is Mike Houston of DISH Network and I was going over your post aboutyour screen goes black when you change the channel. I was wondering is it happeningwhen you go from the DISH channels. Please unplug the receiver for 10 secondsand plug it back in and allow the receiver to fully reset, if you still noticethis issue please e-mail me directly with your account number or account numberso I can check the equipment and notes on the account.

Sharp LC37D44U Power LED was flashing green. TV would turn on, channel indicator shows in upper right corner, sound good, but screen would be black. Channel indicator disappears but screen is still...

I had the same problem. all the service reset would only make the display come on for a few second with no "k" on the screen - only the channel would show up. I purchased a complete set of board for the lcd on ebay, and started swapping them one by one. The inverter boards were the culpret. Tele working 100% since that board swap.

TV will not turn on to channel 4 everytime. I have a cable box and need the tv to remain on channel 4.

As long as the tv is not unplugged it should stay on the same channel when turned back on. If you have the tv plugged into the cable box, when the box is shut off it basically unplugs your tv and the tvs memory is reset. The tv should be plugged in to its own outlet or leave the cable box on and turn off the tv. If you turn everything on, cable box and tv, and have a picture, go into the tv menu and auto program the channels, it should only lock in on channel 4 since it will be the only channel the tv will receive.

TV screen goes black but tv is on. But will stay on sometimes.

i have a 2000ish 32 inch trinitron Wega and i have had the EXACT same problems as you have, except mine was blacking out more and more frequently, but yes if u changes the channel or hit return onto the same channel you're watchin the picture wil come back, but not very long, about the longest it'll show a steady picture is 1/2 hr, but it's usualy going black within every 10-15 mins or so.

I took it to a Sony approved/recommened repair shop and aftet having a look i was told it would cost $200 cd including taxes to replace a 'vacuum tube' or something like that, i wish i could be more specific anout the part. I'm still considering whether or not to go through with the repair. I might just buy a working/used newer Tube Flascreen with HD for another couple hundred dollars. If there was a newer 2003+ 32 or 36" Sony that has a good track record I would love to hear suggestions. I don' trust flat panels, way too mny horror stories, and for every 1 i hear about there's probably 10-20 more.I'll give them another 5 years or so to get their acts together.

On the other had, if i do decide to get my 32" wega fixed i will post the results and the exact pt numbers of the pts used i the repair. Your problem is exactly the same as mine, to the letter. I'm a mechanic by trade, but i have a good feeling they're not going to give me correct pt # until i have payed them to fix it. Or else i'd order the part and install it myself.

Good Luck,

Direct Tv Receiver No sound Black Screen

unplug the power from the reciever for a few moments. plug it back in and let it load. once its finished turn to channel 201. Usually it the reciever is on an unavailable channel (channel with no programming) when it restarted it will go back to that unavailable channel hince the black screen and no sound.

Big black box in the middle of the screen

The black box is there because your closed captioning is on and set to text mode. Some channels send the signal even when there is no actual text to display. You can get rid of it by either turning off closed captioning or changing it to CC1 or CC2 mode instead of text. If you can't find those settings, then restore factory settings as directed in your user manual.

Frozen on a menu screen

Just fixed ours with the same problem. You need to hit the volume buttons on the remote during the time the screen goes black but BEFORE it gives you the "Connect cables" message.It should trick the TV into giving you a blank channel.

Sanyo TVs are made notoriously cheap, and have little glitches like this. Best of luck, space cowboy.
