Question about Sony KP-46WT520 46" Rear Projection HDTV-Ready Television

1 Answer

Screen and volume problem

I have been having a problem with my Sony Wega recently. The volume freezes at a certain level and although the indicator moves the volume remains constant. The only way to fix is to turn the tv off and back on. Now when I turn it off and then back on I get a single horizontal blue line through the middle of the screen and no sound. Will do that several times before I can actually get the picture and sounds back. Any ideas?

Re: Screen and volume problem

Hello, the problem regarding horizontal blue line can be around vertical output stage with IC(LA78045). Please check for cold soldering, resolder the suspected solderings. Best regards.

Power light is green than goes red

Hi beinhauert,

The symptoms you've mentioned indicated that the unit turned to standby mode. This is an indication that there's something wrong on the TV. To help us narrow down where the fault came from, please access the built in "Self diagnostic Screen". Follow the steps below.
In standby mode (red light is on), press the button on the remote control in sequence "Display", "5", "Volume (-)", "Power". Self diagnostic screen's displays its log of error. Please let me know the error code with corresponding numerical value "1" means error has been detected, "0" means no error.

This indicates problems with the image engine. (Lamp does not control the colour). If the TV has not been cleaned recently, excessive dust build up internally may have overheated the image engine. If Sony will not cover it, you might want to consider a new TV.

You will need to replace the G board. You can try replacing the two diodes that usually fail, But because its a complex circuit with the zero cross detection the diode replacement never fixes the issue. Replacing or remanufacturing the G board is the only sure way to fix that issue.
