Pro-710hd When I try to turn tv on it shuts off and will not come on.

    When I try to turn it on, I hear the whistle of the CRTs trying to power up and then the breaker inside the unit turns it off. I have been having intermittent problems with the screen going black and then showing white noise. When I turned it off and then on again after about a minute it would work again for a few days and then do it again.. Now it will not start at all. I guess it is the same problem with the power supply that others have mentioned. Except now it will not start again. Generally what are the cost of the repairs and is it worth repairing? Will it do it again in the future?

This has been successfully answered, but here's some more information:
Your Pioneer 710HD has the classic cold solder joint problem endemic to all of this series of Elite CRT RPTV. The power supply - PS - board needs to be resoldered virtually completely. It's a time consuming, tedious job that if you get wrong, who knows what could happen when you turn it on again? So don't even think about resoldering it if you are an amateur at the soldering process.
I do this job every day then run it out in my test 610HD - same series - and then equip your board with a lifetime warranty on the resoldering work I have done. Please contact me directly, google Mr Bob and calibrations and Image Perfection.
Unless you do resoldering every day as a professional assembler or are an experienced repair tech, I cannot in good conscience advise you to do this yourself. Far too much is riding on it.
However, if you are highly experienced at soldering, resolder everything but the heat sinks, the test points, and whatever has already been resoldered and is still glossy and gleaming, like fresh resoldering is. The solder used in the original assembly of that board was far too thin, which results in these cold solder joints.
And don't do it part way! Many joints that are not bad now will be soon, trust me, and if you have only resoldered just the ones that are bad now - the early ones to go out - and continue to use it, you make your board that much more susceptible to the far more dangerous ones that happen later on, which can damage boards downline from the power supply board.
I am the only repair person I know of offering a lifetime warranty. Even Pioneer does not do that. In fact I have permanently corrected many rebuilt Pioneer boards when they've gone out later. Pix are available at
In your case chances are you have not heeded the warning signs of cold solder joints: intermittent ops, blue flashes, fluctuations in the brightness of your pic and other instabilities.
In the case where one of these units turns on then turns off again - LED in front goes green, then immediately back to red before a picture has a chance to appear - it's "going into protection". Chances are something downline has now been damaged because of the instability of the PS board, which is responsible for powering up the entire unit.
What I would recommend if it's "gone too far" and the unit will not stay on anymore, is a troubleshooting session with me on the phone, which is something I require before allowing a PS board to be sent to me for resoldering if the set's not staying on. Luckily, these sets were designed with on board diagnostics that can be read by technicians from far away.
If it goes green then stays green but no pic appears - even graphics like the Menu - then one of the cold solder joints that powers up the section that powers up your picture has opened up and is now staying open. This has always been remedied 100% by the resoldering process.
If it powers up correctly upon turnon from dead cold, DON'T PUSH IT! If it still has intemittencies, it's in a very precarious, dangerous condition. Many sets have been run past their warning signs, and by the time I get notified and can lend a hand, they are considered totalled and are abandoned. Don't let that happen to you. RUN IT FOR NO MORE THAN 40 SECONDS, and power it down again and unplug it.
If it turns on from dead cold and works properly even tho intermittencies have happened in the past, this is the best case scenario. It means it can be resoldered properly and you'll be home free. Or sent to me for resoldering if you are not a highly experienced repair tech or assembler, in which case you'll get my lifetime warranty on the resoldering work..

Power supply will have to be completely resoldered. It is located on right side of cabinet looking from the back of TV. Advise to let Pioneer Factory authorized service center like myself to do the repair.

It is most likely the power supply. Do not try to fix this yourself. There are LETHAL voltages inside such a TV, which can persist for WEEKS after it has been turned off.

Hello how do i set the convergence manualy on a pioneer elite pro-710hd projection tv i dont have the remote and dont know how to bring the menue up on the tv

You MUST have the remote to perform service operations on the Elites. Look on ebay or do a google search for Pioneer 710 remote.
There is no way to manually do convergence without a remote, and no way to call up the convergence menu.

My pioneer Pro-710 hd 64in keeps shutting down when turn on.

The most common problem this group of sets had was bad solder connections all over the power board that develop after some years of use----most of them I have repaired a total resolder of most or all connections on that board fixes the problem.

I have 65 inch pro elite 710hd 6 years old. Do I have to get analog box

Yes you still have to get digital to analog converter. Although you can feed a hd signal through the component inputs, the tv is still set up to only receive analog signals through the coaxial input
hope this helps

It turns off by itself.

One possibility is the fan has stopped and the set is overheating...and shutting off.
Listen for the fan when turning on the set...or shortly after the set has warmed up......or add a fan blowing in the rear....if the set stays was overheating and needs a fan installed.
One option is to install a good size computer fan in the rear of the TV....(if needed).....they are cheap to buy used and run for years quietly.
