Most people have been talking about the blue light blinking 12 times, well mine is blinking 13 times. Believe me, I'm not crazy...I've counted 13 blinks 5 separate times. At this point, I can't get the screen to turn on at all. When I unplug the TV and plug it back in, the red standby light turns on as if its going to work. As soon as I turn the Power on by using the remote, the blue light turns on for about 10 seconds, then it starts to blink again ( 13 blinks ).
I tried searching the forums for this issue, but wasn't able to find anything. Has anyone else had or heard of this issue?
I've owned this TV for about two years and it has died on me out of warranty.
I have the same issue. It originally blinked blue circular lights and I didnt count them and then when I unplugged it and plugged it back in since it wouldnt turn on now I get a red LED for about 3 seconds and then it clicks off. I cant turn the PDP-5070PU on at all. In the past it had blinked lights and wouldnt turn on then after about 5 hours it would turn on. I had a tech come out and wasted 95 dollars for him to tell me that my power supply works fine and that means it must be the main board.
He now wants to charge me 900 dollars and thats with 300 for the labor.
The main board part number is AWV2312. The main board is hidden behind some framing at the bottom middle. Remember this is the US BB board and not the X or Y board. Also for others, the reference power supply part number is 1H349WA. This board is the large board in the middle top.
Also a free PDP-5070 service manual can be downloaded here:
Or PM me and one day I might send it to you even though I don't sign on here much.
The cool thing is I got to see how you take apart the entire assembly. So my plan is to say F the service rep that wants $900 because I can buy a new panel for that, and I want to do the repair myself. We will see how this goes. My initial plan is to remove and replace the main board, and back up is to replace the power supply, and third back up is to replace the digital board. The service board does have a flowchart to determine what parts need replaced and it appears its my main board but incase that doesnt work out I ahve a few more things to replace that might fix it.
I have already unplugged and removed the mainboard. It was rather easy even though theres about 10+ cables that connect into it.
My overall back up plan is to sell the TV for parts if all doesnt work. I barely even used the TV, average less than 30 minutes a day over 2 years. No abuse no gaming etc.
I wish you all the best and hope you dont run into the dead TV issue I have where your out of warranty and they want an arm and a leg to replace it. Might as well do it yourself
If anyone has any similar experiences to share or help me in my knowledge please let me know.
This is bound to get interesting doing it myself
It's kind of exciting actually. Let the journey begin... I'm just hoping it works Plus the main board costs 150 and the power supply if I need one is 50-100 so I can't lose too much money.
Its sad that this TV is basically old technology and basically worth nothing but a few parts. Maybe this TV isn't as reliable as people think..... love the picture though. Tech told me LCD is a lot more reliable these days
OH and if you want a FREE SERVICE MANUAL ---> GO HERE:
I would recommend downloading asap before it's not available one dayhttp://rc5.ru/upload/pioneer_tv_PDP-...(ARP-3354).pdf
Also theres a white button that has to be pressed when the case is open if you want to run the TV with the case open. The case normally closes this button. When the button is open when the case is upon the TV won't turn on. I think its on the right mid framing arm. It's white in color and if I remember correctly the button is like a triangle. I just taped it into the down position.
