Ge 46gw945 I have this model TV, and now the buttons on the front panel do not work. Also, the channels now will run through on their own. I cannot get it to stay on one channel. Can you help ?

MOST likely a bad high voltage transformer or a Glycol leak both of which were common in this set and the parts for this set are nearly impossible to find (I think by the model number set is newer than 92).

I liked these sets but I would not invest big money to fix one this old.

I have a 1997, 19inch GE TV it comes on for about 10 to 15 minutes then shuts off and will not come back on until a few hours go by or so?? Anything will help Thank You

this is weak power distribution throughout the unit. you wil need to test the power supply board for blown capacitors and resistors as well. replace this vital board if you notice any swollen or disscolored componets.

The first thing to check is the connections to your source. They can easily become loose and/or corroded over time.

convergence circuit problems. prob why blew fuse, 

Over the air channels 60 or above will all be gone soon. The space will be allocated to cell phones and such.
This may be what you are seeing.

I THINK YOU HAVE A BAD KEYBOARD--SOMETIMES THE KEYS STICK AND IT COULD CHANGE CHANNELS ,VOLUME GO UP AND DOWN,TURN ON ,OFF ETC.......GO TO A LOCAL SERVICER AND SEE IF HE CAN SELL YOU A USED ONE --YOU' LL KINDA SEE WHATS INVOLVED TO REPLACE--YOU MIGHT WANT TO TACKLE THIS IF TECHCANALLY SMART---ONE OF THE TRICKS IS TO "NOT TO BREAK THE OLD ONE WHEN REMOVING"" BE CARFULL...

YOU'VE LOST VERTCAL DEFLECTION---THIS COULD BE SOME PARTS IN THE VERTICAL SECTION BAD,,LOST A VOLTAGE GOING TO THE CIRCUIT OR WORST CASE ----FLUID FROM THE PICTURE TUBES HAVE LEAKED ON THE CIR BOARDS CAUSING THIS PROBLEM---NEED TECH FOR THIS ONE!!!!!!!!!!!

How old is this set? If any age, might be time for a replacement, you can get a 50" for under $1000 now. Dont know about your issue, I have never heard of one not turning on because of a timer, suspect you may have a micro issue, the power cord unplug would be advisable, but sounds like you tried it, have you tried the buttons on the front? Do you clean the screen with something liquid? Some of these the buttons go bad and confuse the micro if you use liquids on the screen and let some dribble down the frame. Might pull the speaker grill off and there should be 2 1/4" screws on 2 brackets loosen and the brackets will drop, the screen can come out and there is a long connector that goes from the front to just behind the middle tube and if you unplug it it will kill the buttons on the front and if it is your problem will allow the remote to function, reassemble reverse of disassembly.

Try unplugging for 12 to 24 hours. if that doesnt help replace the convergence IC's
