Re: Pioneer sd532hd5/kuxc/ca powers down on its own

Could be a few things.First check your sleep timer.Sounds like a fail safe mode that when the tvs left on accidentally it shuts itself down so it wont overheat and die prematurely.The last resort is to remove the circuit board and carefully inspect the solder joints near the power supply with a magnifying glass and a bright light.Then resolder those.

Have a Pioneer pro elite 730hdi. When you try to turn it on (main power, not standby), the tv cycles from the red (standby) light with the normal click to the green light, then one second later, it cycles...


Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like, to buy a whole refurbish power supply board for the replacement.

Hoping this will help in solving the problem....

Tv turn on and inmediatly turns off

The power protection circuit has shut it down by turning the power relay OFF. The problem is some section of the set is drawing too much current and the power protection circuit detects this and pulls the power relay OFF. The most common problems are with the high voltage section, deflection circuits or audio amplifier. Could, rarely, but could be the main power supply. So, you can take the chance by holding the power relay ON for long enough to see if you can get a clue as to what section is not working. For example, if you hold it on for a few seconds and don't get any raster you know there is a high voltage problem. Or, if you get a raster but the picture is messed up mabye the problem is in the deflection circuitry. Or, if there is a good picture but no audio, could be the audio amplifier, etc. Using the above procedure you may be able to get an idea of what is going on inside the set.

DON'T FORGET, before you do anything, DO A HARD RESET AND A WHACKING TEST: just disconnect the power cord for 4 hours to restore the internal soft codes to factory defaults. Bang on the set in search of a loose wire or cold solder joint!

Problem with pioneer elite pro-99

We are having the same problem of the Pioneer Elite Pro-99 turning itself off all of a sudden. The red 'non' power button comes on as if we had turned it off remotely.
We would love to resolve this. If you can help let us know.

Picture mode changes to zoom by itself

It sounds like an eeprom issue. But you can try to reset the set. Turn the set off by the main power on the set. wait a minute or two then together push both the main power button and the standby power button. This should resett the tv. If that doesnt work you will need service as the zoom and the various modes are all controled by the eeprom. Only hold the two buttons for a second. sometimes you will hear the crts discharge while resetting.Hope this helps
