Sanyo AVM-2054 TV Video interruption

Hi, Our Sanyo TV turns on fine but after a short period of time (varies), the picture is overlaid with a large black box leaving about an inch and a half border all the way around the screen showing the TV program on the border only. When menu button is pushed, black box disappears, but reappears as soon as graphics clear from screen.

This AVM-2054 TV has a G4Z-20540 Chassis.

Any ideas?

    After the TV is on for a bit in the mornings, a black box appears and the picture can still be seen around the black box. It used to really happen on ESPN, now it happens on a local channel and various channels, but not all channels. I can turn the TV off and back on and the black box disappears. Most of the time when I get the black box, there are letters and symbols like this: a~a~a~g*fg^g^g^g^. I used to write them down thinking they meant something, but now I don't.

SOURCE: Screen split with black bar through center, top of picture shows in bottom

It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck

It sounds like you have the Text feature on the closed caption option turned on. your going to most likly need an original remote to turn this feature off as far as i know of. If you do not have an original toshiba remote to turn off the clkosed caption or in some sets you have to go into the menu to turn this feature off, maybe you can borrow one from a friend that has one or you can get one from http://www.remotes.com.

Loud buzzing sound on Sanyo AVM 1909


I had a problem like that so I disabled the tv's onboard tuner (input source)and now we use the cablebox's video and audio out to the video and video in jacks on the TV this will work as long as you have a cable box or sat reciever for your video and audio source and of course your TV must have video and audio inputs so it will work.

Good luck Rich

Sanyo Model AVM 3659G won't recognize DVD player


Hi,

Let's try the easy one first:
  • verify the connections, normally yellow for video, white & red for audio. TV has to be set to Video 1, A/V or Channel 0;
  • in some instances, it could be a single coaxial cable. If it were so, the TV has to be set to Ch 3.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

Sanyo PLV-55WM1


Hi I read your problem with the Sanyo PLV-55wm1. It sounds to me like a power supply problem. Like most new electronics devices, they use a switched mode power supply (SMPS)to supply the voltages to the rest of the set. Many of them use a current feedback loop to sense a short in the circuits that it powers. I would check for a shorted diode in the high voltage section of the tv. If any one of the components is shorted around the high voltage circuit, The current control line will be zero forcing the regulator to shut down.

TV sounds like power up for few seconds then goes off


You have a short somewhere causing the power supply not to start. Most likely a shorted horizontal output transistor and maybe a flyback transformer which caused the transistor to short. It would have to be checked out by a technician to find out exactly happened. Stargazer
