Question about Pioneer PRO-700HD 64" Rear Projection Television

Continuing questions from Tony Fidaleo

Comment by TEFidaleo, posted on Jul 26, 2008 After our conversation I began to pull the power supply assembly. I then noticed another bank of fuses and found a 5A/125V (Pioneer part number FU206 per the circuit board) fast burning fuse was burned out. I went to Radio Shack and purchased a bag of the 5A fuses and had the fuse (FU101 10A/250V) tested that I could not see through yesterday and it checked out as good.

I replaced the burned fused and reconnected the power cord but the fuse quickly turned red and burned out (I did this twice and then unplugged everything).

Per the partial service manual I purchased yesterday (did not realize there were 2 parts to the manual) I noted this fuse is part of the Power Supply Assembly (Pioneer part number AWV1710).

Per the pioneer site the power assembly is in stock. At this juncture I prefer to just buy a new board and insert. However, before I order a $352 part I want to make sure that is the appropriate course of action, i.e. I don't know if that fuse could blow from a problem in another area/board. Also if I replace with a new board does that impact the TV's adjustments in any way?

Your recommendations are appreciated. I would be glad to email the Service Manual I have if that helps, it is in a PDF file.

Panasonic pt-47wx42 5 blinking power lights


5 blinks is short protection, it means a short on the 140 volt line coming from the set's power supply.

Most likely is the horizontal output transistor is bad.

Let me know if you want to know how to get at it and test it.

The set has a light box that contains everything that can be removed for this kind of service.

I am very familiar with this set and have fixed hundreds of them.

Hello, asnowman here.
I had to reply to this post, as the other would not let me.

Your question:
Comment posted on Oct 26, 2009 Thank you for your help, do you know what board this is on? signal, main, or power? Your televsion is the 73411, and I think that your convergence IC's are on the center board, (called the power board, even though it doesn't have the flyback on it), if they are not they are on the signal board. You can't miss them they are attached to a very large aluminum heat sink and the IC's are very large as well. I hope that this answers your questions. If you need further assistance please comment to this post and I will try to help you further.
Thanks for using FixYa

Tv after power surge


There isn't really an absolute answer to your question. The power supply affords some protection to the rest of the set when the components designed to prevent short-term power spikes activate but their primary purpose is the protection of the supply. There is surely a fuse on the line-side of the supply, then there are two more devices normally included (they cost little) that will force the fuse to blow if a certain line voltage peak is encountered, a type of resistor that is actually a semiconductor that has little effect until its design is exceeded; it then looks electrically more like a  dead short, causing the fuse to blow. The other device doesn't do much after the first few cycles of AC and is there to reduce 'inrush' current. Well-designed supplies will have fuses on the output side of the supply that protect specific voltages and circuits.
Could the low-level circuits have been affected?  Yes, but in some cases, only a working supply and time would show up some kinds of failures.
In addition, I always include the suggestion pasted below:
If you live in an area of frequent lightning strikes, investing in a 'whole house' surge arrester makes sense.
These are installed in the main breaker box and any brand I've seen comes with a $10-25,000 insurance policy to replace any dead appliances that fail despite the surge protector.
They cost $150-250 US plus installation which you can save if you are afraid to DIY.

Blurry shaky pic


It sound like you have a leaky capacitor in your power supply, or video circuit, that is causing noise in the picture. I would have to refer you to a television technician in your area. This would seem like a simple repair. Leaky capacitors can become stable after they warm up.

I hope that I have provided the correct information that will assist you in the resolution of this issue. If you have any questions, please post back with a comment to this thread.

Continuosly blinking green light and tv won't turn on.


Either bad capacitors -vented - on power supply board or bad E2P eprom board on DM board.Probably the capacitors-4-1000Ufd and 2-3300ufd.You should get expert help from reputable tv shop.Not really do it yourself fix either way.

Power problem on Pioneer Pro-700HD


The failure is not on the power supply but the convergence amplifiers STK ICs have the 24 volts shorted.
If that fuse is blowing, de-solder the convergence ICs and put a new fuse to power up the TV; you should see distorted video when the TV powers up and the fuse should not blow.
The service manual migth not help much in this case since the failure is easy to pin point.

Good Luck.

Sound no picture?


I have no solution for this problem and I'm not sure I can fix it without taking it to a repair shop. The replies I got yesterday did not help.

Once I look at the schematic diagram, I might be able to know the part that is blowing that fuse.
