My pioneer 5020FD Kuro tv. when I plug power to the unit, a blue light blinks 8 times pause 2 sec. and blink 8 times repeating this and if i press power button it clicks red light and makes a clicking sound and goes back to the blue light blinking again, it did this once before and the picture came on fine until i turned it off and now it just blink the blue code.
Check in your unit for a switch on side wall or near ceiling for selecting which AC unit gets power. Should be front, back, or both. Usually black knob to turn. Sounds like 12 volt power getting to it that tells it what to do, but also need to switch over to allow 120VAC power to actually supply power to it for running fan, compressor etc. Be sure to check all breakers in panel as well. You will probably not be able to run both at same time unless plugged in to 50amp or plugged in to 30amp, and generator running as well. I'm thinking a 94 only has 30amp power cable anyway.
Ur tv turn on now,hear alot of clicking?The tv LED light "lamp" on front panel flashes or light up?The tv projection lamp is dead.The Ballast board dead too,if hear alot of clicking?The ballast board help to ignite the projection lamp.
If this clicking is a continuous clicking sound its likely that its coming from the ballast.The ballast is the component that powers the lamp.If this component fails your lamp wont ignite and wont allow the start up to continue.
I have the same model as you. Plug in the transmitting unit into a good working power outlet. Make sure you have the audio connected to a loud source. Turn on the source device producing the loud audio to be transmitted to your headphones. Now see if the transmitting unit's LED light is on. Check headphones for audio. (May have to tune in the headphones and adjust its volume as well). I recommend that the source of your audio have its built-in speakers off, while still providing audio out to your transmitting unit, via an external audio output. Check your source manual or look for audio jacks on the front or back. There may be a setting to turn this on and for the main built-in speakers to be turned off as well.
If this does not work, unplug the transmitting unit, and then plug it back in again, after waiting for about 10 seconds - all while audio is being provided to the unit. It should come on.
Remember that if the audio to the transmitting unit is quiet OR off for about one minute, the transmitting unit will turn off and you will hear FM noise, loudly, on your headphones. This is due to the "lack of audio" timer built-in to the transmitting unit.
The first thing in this unit is to check the ribbon cable that goes from the front control panel to the back ssb board, I would unplug and replug to make sure seated properly. Then try it again. There are alot of screws to take out but worth it if this solves the problem.
Although you didn't list your operating system, I'm assuming it is Windows and offering a suggestion to clear up the issue based on that OS. Go to settings, and then to control panel. Once in control panel look for "power settings" and click on "custom". This will allow you to turn off all power saving modes by clicking "never" on when the screen is turned off or goes to sleep. If the issue is caused by the power saving mode, this will end the problem.
