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.

Re: 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.

Everything from Channel 14 and up won't reset

If you have just an air antenna and your tv is set for cable and not air, you will not pickup any channels past 13.

Channel three is missing

Hi pasu, Normally if you can get/program Chs 2 and/or 4 as well the other channels, then Ch 3 should also be programmable. If this is not possible, perhaps you can try to manually program by selecting "03" and add to the memory "+" in some brands/model. If this is still a no go, perhaps you should seek the services of qualified professional since this would apparently be an internal software problem. You can also try a hard/full reset by unplugging the TV from the mains for couple of hours or as prescribed by your TV's user manual. If the TV has Video input features, a possible temporary work around the TV's Ch3 problem is to use the Video1 or the Audio/Video INput of your TV and use an old VCR to connect to your cable box. Remove the coaxial cable from your cable box to your TV and connect it to the RF/TV INput of your VCR. Use a 3 way RCA to RCA connector (usually Yellow, Red & White) to couple the Audio/Video OUTput of the VCR to the Audio/Video INput of the TV. Select Video mode in your TV (so it doesn't matter even if you cannot program Ch3). Power up your VCR, select Ch3 in your VCR's tuner. I assume that to select channels you wish to view, you use a remote and channel selection is done in your cable box. What worries me is "...went to a fuzzy black and white screen..." which is indicative of another fault. Hope this be of some help/idea. Post back how things turn up or should you need further information. Good luck and kind regards.

How do i put it on channel three manually?

If the remote to your box can be paired with your tv then you should be able to fix this problem simply by pairing digi remote with tv and while in tv mode on remote, hit the input button. That should change tv back to cable/antenna setting so that you may access channel 3. Hope this was helpful.

TV has black section

I would contact you service provider, if you have the problem on only one channel then it's not your TV. Can you verify that channel on a different TV?

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,

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.
