Because your problem appears after 1 hour... suggests me that your TV's tuner unit or cable box is at fault.

After the unit generates heat, the components (capacitors) in the tuner is affected and throws off the frequency of each channel.

  • if it is the TV monitor's tuner rather than the cable box, then you would have to have it serviced by a repair facility.
  • if it is the cable box, just call your cable company to replace the box at no charge to you.
Good luck!

Fuzzy picture


Sounds like an AGC [Automatic Gain Control] problem with its video IF stage circuit. Contact any service technician, or service center. This is not a user repairable fault.

the variation from higher channels from lower channels, few things changes eg frequency, voltage, and current.
take your tv to a w/shop and have the following
tunner voltage pulse variation on a avo meter has you change channels. if the difference of voltage is not unform when you are changing from to channel then you should change the control ic on the rf stage or check the capacitors a round the rf ic for variations in value.

SANYO MODEL DS27510, CHANNEL DISPLAY IN CORNER WON'T GO AWAY.


If you can program a Comcast remote or another universal remote that has an info key, you can get rid of it. I just succeeded in programming my comcast remote thanks to Dave Taylor:

One channel fuzzy


Tis is an ongoing problem I seen increase alot over the past few months. From what I can gather, all the channels being broadcast over going from the analog to digital, there's no big suprise to anyone. However, the change from analog to digital is changing at a faster rate, so when you look at the TV some channels will be fine and others will have grey lines, fuzzy picture. The only solution-you need a TV with some kind of digital tuner. On the TV itself if the (TV has one) it will say "SD" or "ED" which stands for standard digital or enhanced digital.

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.
