Re: GE Model #25GT511 Power on, no picture or sound

The question I have is if the tv stays on but with no pix or sound,we have a way to check,if you place your forearm in the face of the picture tube and the hair in your arm stands up it means you have the high voltage needed to light up the tube but something else is missing like the screen voltage or it has a loose conection in the crt board,if the hair in your arm does not react to static then we are missing the high voltage and the problem might be more involved and related to the horizontal circuit not creating the high voltage needed.If you are familiar with tv service you have a few places to check but if you are not to familiar play it safe and call for assistance from a professional servicer.Let Us know how it goes please.

Lost Manual. "Clock set, year, month, etc." on screen. Working with "Menu" button doesn't fix it. How do I get it off?

There is usually a cancel button.
If that does not work, try unplugging the TV power cable for two minutes.
If still no luck , then give me the complete model number, or enter the model number here to access manual.

Dear FixYa, I have a Sony Trinitron color TV, purchased June, 1999; Model #KV-20FV10. With the digital converter box hooked up I got a beautiful picture but no sound. One of your experts suggested I run...

If you have sound from your set using a VCR, the TV isn't at fault. And I warn you, don't be too quick to dispose of your old Sony, I help those who have sets bought within the last year or two that are failing everywhere; these have sophisticated power supplies that demand very high quality components to function reliably and mfrs. are loath to spend the extra pennies and as a consequence, they are failing way too soon but often just after the warranty expires.
You just need to ferret out the right audio paths to complete your system if you find that the set works OK with a VCR or DVD player.
The conversion hasn't done any damage to your Sony, you are only not connected as you need to be.

Can't get my VCR to work

FIRST!!! Make sure you have the coax or AV cables plugged into jacks marked out on the machine.....then....

*If you have it hooked up with a Coax cable, you should immediately have picture and sound when you turn it on. Make sure you have a dvd/vhs running and switch between channel 3 and 4. if this doesn't work, make sure that you have the cable connected to the one marked 'in' or 'cable in' or 'ant in'. then retry the previous steps.

*If you have it hooked up through A/V cables (Red/Yellow/White), make sure you have them all connected to the same set of jacks. They should be labeled Aux 1 or something similar and are generally surrounded by a box molded into the TV's plastic casing. You will then have to use the TV remote to switch TV/Video settings until you get to the one that matches the Aux jacks you have it plugged into. Again...make sure a dvd or vhs is running and keep flipping until you find a picture.

Hope this helps!!!

RCA 25GT511 - fuzzy picture slight static sound; wiggle coax rear mount temp resolve

There might be a bad (loose) connection in the RF isolator or the tuner (both are silver boxes. Try to unplug the coax and bend the RCA tabs in so that the connection gets firmly made when reconnected. This may help. If it does not The connector may have to be replaced.

TV clicks but no sound or picture

if this is a crt it is most likely not worth the repair specially considering the size of the set. Most parts for them cost more then the tv itself sorry for the bad news if its not a crt then thats a different story

Blurry screen GE 25GT511

hi There shouldnt be much in the focus system to go wrong as really there is nly the tube base and the flyback transformer. The usual for a TV is the tube faulty so its beyond repair. You could try the focus control, this will be on the flyback transformer. Back off TV, look for a heavy lead going to the dome of the tube at centre top and with eyes ONLY follow that back to the flyback transformer. On the side of that transformer is 2 screws, one near the top is the focus control. You will need a screwdriver to turn it and it usually has a seal to be broken. That will turn from say 8 o clock to 4 o clock no more, turn it up clockwise, try both ways. if it almost fixes but not quite it would be the tube. good luck
