Sound ok, but no picture

When I turn the tv on the sound is ok but no picture. If I hit the tv on the side the picture comes, sometimes. This problem has been going on for about a year. Now the picture does not come on when I hit it on the side. However, if I let the TV on the picture comes on, anywhere from 15 minutes to two hours. When the pictures comes on, the quality is perfect. Q. Any hints as to why the sound is OK, but no picture when I turn TV on? But if I let TV on it eventually the picture comes on. Any suggestion will be appriciated. Thank you, Alex

The other two solutions prior to mine are retarded!!! I've worked in a Tv repair shop for over a decade and the problem is the same as 99.6 percent of all other electronics that function correctly when you smack them! "BAD SOLDER CONNECTIONS" STEP1, plug-in and turn on the device. DONT BE A CHICKEN SHIT! unless! It's a microwave oven,those can kill you!anyway you need to open up the device,in this case the Tv.plug-in and turn on the device,Find something non-conductive,like the handle of a screwdriver holding it backwards,if you don't understand just use somthing non-metallic like a clean wooden spoon!Anything wood or plastic, then tap around the circuit boards. YOU WILL NOT GET SHOCKED!!! If you use something non-metallic! eventually you will get a response weather it corrects the problem or causes the failure you have located the bad solder connection .STEP2, Now unplug the device from the wall! locate that area on the bottom side of the circuit board and resolder the indavidual solder jonts in that vicinaty more often than not,It's a part that is screwed or clamped on to a metal plate or block. DO NOT SOLDER TWO SEPERATE SOLDER JOINTS TOGETHER! IF YOU DO AND CAN NOT SEPERATE THEM GO TO A RADIOSHACK OR SOMEWHERE AND GET SOME CHEM-WICK OR SOLDER-WICK/DESOLDERING-WICK IT LOOKS LIKE A ROLL OF BRAIDED COPPER WIRES! PUT THAT STUFF BETWEEN THE SOLDERING IRON TIP AND THE CONNECTIONS YOU FUCKED UP! AND IT WILL DESOLDER THEM! IF YOU DESOLDER THEM ALL THE WAY RESOLDER THEM WITHOUT SOLDERING THEM TOGETHER AGAIN! REPEAT STEPS 1 AND 2 UNTILL THE DEVICE NO LONGER FAILS. PRECAUTIONS: 1 ONLY USE A PENCIL-TIP TYPE SOLDERING IRON,2 DONT USE SOLDER THICKER THAN ROUGHLY 2 MILIMETERS OR 1/16 OF AN INCH! THE THINNER THE BETTER! "YOUR WELCOME" FOR MORE HELP YOU CAN REACH ME AT

The longer you slap the set silly to make it work, the more the tech will charge you to fix it, as a bad connection can make other parts go bad. so if you continue using the set like it is, it will kjost likly cost you double to repair in the future. now if you do not plan on investing anything into this set, then go ahead and use it as is , but I must warn you , a bad connection is the right area of a TV set canm cause severe heating up of the connection, and that can lead to fires!

The good thing is the set reacts when you hit it in side,the two symptoms are related and I will suggest to call for professional help now and the repair will not be as expensive as if you try to use it like that.

Check its solder terminal at the CRT board [Filament voltage]. It sounds like the filament do not glow after some time due to a loose contact at the CRT base connector sockets. Check it.
If this does not help, check the ABL circuit for any open resistor.

TV turns on, only voice,no picture,red light will flash, no click

You may have to resolder your vertical IC. This seems to be a common occurence for many Sony TVs. This is my first diagnosis when I get one of these in. But, yes there could be a bad ground almost anywhere. You will need to pull the board out and resolder any IC mounted on heatsinks and any large power resistor and resolder the pins connecting the flyback transformer to the board. This tip is always the first place to look for in repair. Good Luck and be mighty careful. Thanks for asking!

No video/audio when pressing remote control or on the TV set

Moved my TV to another satellite receiver.
I received picture & audio.
Then I moved the TV back to its original position.

Now it works OK.

I probably hit a button that shut off my picture & sound.

I am mystified.

Thanks anyway.

Toshiba tv when switched on no picture n no sound comes

**presuming** this is a horizontal, very thin line right in the center of the tube, and sometimes the picture is ok, then the vertical circuitry has one or more bad solder joints.

A ***QUALIFIED TECH*** needs to resolder the joints in this area. This is not a beginner soldering job. Special care must take place to avoid electrical shock or WORSE!! seriously.

Power light blinks and no picture

No picture - screen is empty. Sound is ok
Check IC101 (BA7630F), if video signal comes to input (pin 1) but not present at output (pin 14) then replace this IC
No picture and sound, only a high pitch sound at switch on
Remove horizontal transistor and measure the resistance across any two pins. This value should be no less than 200ohms
Picture fades away few seconds after start-up till no picture. Sometimes no picture at all. Sometimes picture OK for longer. Sound unaffected.
Faulty joints on CRT pcb. Cracked solder joints at tube socket connections on CRT circuit board. Caused variable supply to CRT heaters. Resolder all socket pins to pcb.
