Re: Pioneer 610HD Turns on the will shut off to stand by...
You have problem in the power supply section of your set. You can obtain a service manual for 12.99 at the following link and they provide free help in diagnosing your problem. They will also email the manual to them if you click n the contact us link and request they email it.Hope this helps. http://servicemanuals.vstore.ca/

It sounds like a microprocessor that has latched up.
Try pulling the AC plug and letting it rest for an hour or two, the problem may cure itself.

you can replace your the convergence chips on the convergence board. The board is to identify because it has a large heat sink. The convergence chips normally starts with STK... After you find the chip, you can buy online (ebay has a lot of listing) and costs around $10. If you know how to solder, it is very easy to do. I just replace the convergence chips on myPRO-610HD and it works perfectly.
I had a similar problem with my Phillips 42 in. LCD HD TV.
Here's the problem. The Power Supply Board. I opened my TV
up(warranty was up of course) and found several bad capacitors.
Phillips and several other companies were sold capacitors that although
were highly rated failed within 5 years because of a lack of
preservatives. All sorts of electronic equipment is now being effected
due to these defective capacitors.
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.
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 www.avsforum.com. 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. DO NOT ALLOW IT UP TO NORMAL OPERATING TEMP AGAIN - EVEN ONCE - UNTIL FIXED PROPERLY. 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.. Mr Bob510email@example.com
You may need the power supply board resoldered as I had the same problem. The guy listed below can do it for you as I shipped mine from Illinois to him in California... Piece of cake getting the board out of the back and it's not too fraigile... Just pack in bubble wrap and it will be fine. My TV is now working great.
BUT DON'T DELAY AS SOONER LATER TV WILL NOT RESTART..
