Question about Pioneer Televison & Video
I have a Pioneer PDP5080HD Plasma TV 5 years old. I was watching it and "POP" The tv went off and the power red light was blinking 7 times. I doen loaded the service manual and saw that it could be the Y drive board part# AWW1260. Service shop wants $450 for this part I found a new board for about $100. It was not difficult to take the TV apart and replace the Y board. The TV now blinks red 2 times. THe blinking code looks like it could be power supply, Y Board or X board. The power supply makes more sense on what could be wrong. I think I am going to have a technician come over for $150 a hour and try to resolve the problem. I am debating on ordering the AXY1157 power board and attempting to resolve this issue. I dont have the proper volt meter and wave scope the service manual states to obtain mesurements.

Ok here's how I manage solve the problem... Having the back removed opens the contacts on the interlock switch so I guess if it powers up in this state it senses the high voltages are exposed and for safety shuts down... After this the unit will not power up and the power led flashes red continuously as described before…
After some thought it occurred to me that there may not be a problem at all, just be a simple reset function for this condition… I managed to find an easy solution to this… Just call up the hidden engineer’s service menu – On 3rd generation Pioneer Plasmas it’s as follows > Power down the screen > Hold down the “Input” and “Vol +” buttons on the front > Power the screen up and the Service menu comes up on the screen > You don't need to change anything just simply power off and from then the screen should operate as normal…It did for me so I’m well happy now!!
I hope this information will help someone else one day – Good Luck!!…Rob UK…

Television is not working, screen is black, blinking red led.
Answer Television is probably malfunctioning due to electrostatic discharge. Try resetting the television by unplugging it from the power outlet for 10 seconds.

are you using a PC to feed a signal or maybe a cable with an adapter?
I had the same issue when I used one of the rear HDMI ports to show a PC display. Apparently there is a software difference between the rear and side/front ports. Inputting the PC through the side HDMI port has solved the problem for me (so far!)

While not aware of particular problems with this TV (others may know it better) based on the description and my practice with plasmas I'd be inclined to believe that one of the two sustain boards is near end of life.
Could also be problems with the power board, usually caused by dried out capacitors, but could not find reports of that through Google, so my first idea holds.
If you have a screwdriver, muscules to move it around and patience to unscrew all the bolts that hold the back panel you can actually test my theory by disconnecting each sustain in turn and seeing if the TV powers with no problems.
The sustains are the two large boards - one of each side of the display - left and right. Each sustain has a pretty fat power cable connecting it to either the power board or the other sustain (through which it may be getting power).
If I have to guess I'd bet on the Y sustain, which is the larger of the two, usually staying on the left side.
But that's just a guess - could be the other as well.
And, of course, could be just about anything else.
This is just best guess based on experience.

All you need to do is to open the back cover of the television to check for burnt transistor , this is always the problem , for you to fix this it require a basic knowledge on electronics,
Your power supply board is not yet 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 Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
I hope this will help out in solving the problem
