Pioneer plasma light wont come on just stays in standby and when i push the standby button it comes on

SOURCE: pioneer media receiver won t turn on

If the light on the media reciever doesn't come on then the power supply in that needs to be replaced by a service tech. If you disconnect the 2 cables from the media reciever and the panel and then try to turn on the panel it should light with red and green squares for a few seconds but will turn off as it needs the media reciever to be connected.

You will have a fault in either of your sustain boards. Possibly just a fuse open circuit but more likely to be something more serious on the driver circuit. the best remedy would be to contact your service centre especially if it is still under warrenty.

Could be variety of reasons.

Service manuals usually say to check all standby voltages from the power board and then eventually try replacing the main logic board.

Some TVs have more than one standby circuits and there's a chance you have one of them working and the other failed...in that case you won't be needing a main board.

The bad news is I don't have the schematics for your model handy.

Still...hope this helps. If it does, please rate it :-)

The 5 blinks error code means a faulty power supply. Pioneer has extended the warranty on certain models by 4 years(1+4 5 years in total). So if your tv is less than 5 years old contact pioneer for a free replacement power supply. They won't charge you for the part only for labor
