Question about Pioneer PRO-100 TV

1 Answer

This Pioneer Pro 100 only shows snow when turned on and eventually it will come to show a picture, but sometimes it is hours later before it comes on.

When I turn on the television, there is nothing but static sound and snow. Evenutally, the picture may come on but then will start to flicker and go to snow again. The weird thing is that the Picture in a picture will show clearly, but the main picture is just blank with no sound. I have left it on for days at a time and still had no picture, but other times, the picture comes on right away and works fine for a while. Help.

Your set will one day soon not come on at all. theres several capacitors on the PIP board if your set has PIP or the capacitors in the power supply. A good tech should know where to check as this set some say is hard to work on but i quess its like anything you work on for a bit gets easyer. Call an authorized repair center for pioneer. Good Luck

EchoKaos may not have resoldered his PS board, which most units in that line need. This will most likely solve the problem. A virtually complete resolder is needed on that board, not just the obviously problem areas.

If not -

If the hor lines are upward and curved slightly and a couple of inches apart, then the blue Screen trimpot on the focus block is most likely turned up too high. When turned down the lines will disappear.

This mucks with your grayscale, but then it's trashed anyway by now, and after reducing it, you will have to do a new grayscale on your set, or have one done by ISF. Or a tech who knows how to set the Screen controls, since ISF does not teach that.

My set is doing the same thing again. The last time I fixed this (4 years ago) it was a capacitor gone bad in the power supply for the 24v standby circuit. (C166)
The service manuals can be ordered directly from Pioneer Part Number ARP3014 for Pro-100 model.

Hi If you haven't fixed this problem yet then this should take care of it.
I also had the same problem with the same tv. Its in the power b oard. You need to re solder all of the joint connections on the board.If this doesn't help you can search out the problem with tv since it is a very common problem
hope this helps

If your Elite 510/610/710 - and the earlier 520/620/720s - works fine when you turn it on but starts to go hinky on its reliability once it has warmed up, you still have a shot at getting that sit remedied for a very nominal fee - or nothing, if you know what you're doing and are an electronics professional. Those models were improperly soldered at the factory on their PS boards. Those PS boards took years to go bad, but now that the constant barrage of expansion and contraction of the too-thin solder joints has started its inexorable journey towards taking down your set, the clock is ticking. You don't have much time.

One thing is very important, and I can't stress it enough: STOP USING YOUR SET NOW. Things could get much worse if you do. That means NOW, even if you are watching it right now. A deadly spike caused by the bad solder joints currently on that power supply board could be getting ready to be produced by a connection that is getting ready to separate as we speak, and that spike could take out one or more of the boards downline. One guy who called me had kept using his set for months with these intermittents happening, and eventually both the converence and the deflection boards went out, both in an instant. The set would not turn on again, and built-in indicators on the circuitry showed 3 boards now needed attention. With 3 boards to now have to deal with, he decided not to get his set repaired at all, due to the now tripled expense. His set was now totalled. It tears my heart out when one of these fine machines goes down for the count because of misuse - continued use when it's obviously hurt - and is then DNR'd by its owner. That all could have been avoided by taking action promptly rather than continuing to tempt fate, on his part.

Send me an email requesting it, and I'll send you back an emailout on how to remove it, what it costs, how to wrap it and send it, where to send it, etc. I can't divulge certain aspects of all this on the net here, must keep some of it close to the vest. Will be glad to tell you personally, by email or on the phone.

I will tell you this much - I charge $275 for the resoldering op, you pay the shipping both ways. That's less than it costs to get a replacement board from Pio and have a local Pio warranty station install it.

Keeping the same board in your set rather than replacing it is the way to go, IMHO. That way the voltages it was set up with originally, stay the same. If you get a replacement board, those voltages can be very different, affecting the precision of settings downline. Voltage regulation only has to fall within certain parameters, so different PS boards will produce different sets of voltages. The PS board and your set are now a matched pair. The best way to retain your precision in downline sets of settings, is to keep your original board in the set, the one your set was originally set up at the factory with.

To find the PS board, follow the power cord from the wall. It will lead you right to it. Use the big bubble-wrap to send it rather than the small stuff, and box it in an oversized box for the journey.

This is typical of dried up old capacitors. The problem can be cured by keeping the TV on for days. The moisture in the air will be the cure for the dried up capacitor. It will be good as new if you use more frequently.

Tv turn off by itself.


I have been dealing with the same problem with the identical set. I'm pretty handy so rather than junk the set, I took off the rear panel and stuck a small fan in the back to cool down the inside of the cabinet. I love the picture on this TV so I'm doing all I can to save it. Sometimes it doesn't turn on so I have now taken off the front panel (speaker cover) and also the front access panel. I carefully reach inside and have to wrap on the part (with a long wooden spoon) that I hear clicking from when I hit the power button. I used to just give the cabinet a swift kick and it usually would turn on, sometimes after several kicks. Kick it, then hit the power button. So whatever the problem(s), it's not keeping me from watching a gerat picture. I have a feeling that if I took my air compressor and blew out all of the dust from all over the components, it'd probably solve the problem of it shutting itself off after an hour or so. Why it doesn't always turn on is anyone's guess, but a good tap or two with my wooden spoon here and there and it turns on eventually.

TV picture shakey/blurry


Rachael, The Pioneer PRO-100 is a rear projection 51 inch TV of 1000 lines resolution. I do not know enough about the type of projection to answer this question. They use Liquid Crystal Display panels through which a powerful light shines, or Texas DLP micro-mirrors which reflect the light. As the deflection is digital in nature it does not `die' like a C R Tubed television. Are you saying now it won't come on at all, and shows the red light? I can only think it is like a projector and has fans to cool the lamp. To start with the fan may get squeaky due to a dry bearing (common problem). Eventually the fan will stop or not supply enough air and the lamp will overheat and burn out. They cost 250£ to 450£ to replace.(UHP mercury vapour lamps) In your TV it seems that something in the optics has bad distortion and de-focussing due to the overheated lamp. This could be much more expensive to put right.
