Question about Pioneer PRO-99 TV
We have an older pioneer elite pro-99 and a few weeks ago it shut itself off when we were watching something. Ever since then when we try to turn it on, the power comes on for a split second ( no picture or sound though, just the green power button comes on) and then immediately shuts itself back off (the green power light turns to red). Any ideas or suggestions on how to fix this or what the problem might be? We have the same problem. Also, a click is heard inside when the power button is pressed and the standby/on light turns green to red.
This is a very common problem with these sets. I just had the same problem fixed on mine. Too bad Pioneer's service line is always busy and too bad they don't post the answer online. I couldn't believe it myself, the circuit board (approx. 12x13) needed to be resoldered. No parts required. The very reputable tech just turned the board over and started applying solder to about a hundred of the solder points. The set is working fine now.

The click you hear is safety switch tuning tv off because it detects there is a problem.
Only simple thing you can try is keeping tv off for two hours, this will drain power off from TV resetting it, can fix some problem.
More likey your tv power supply is gone and need replacement, if it is not apower supply, then is some onboard component that has blown.
A call in for a technician will cost you $80, see if it is work.
Try unplugging first.

It is most likely a problem with the power supply module and it will need to be replaced

Your tv's hardware might got the problem. this should fix with an expert technician that they have a tools for fixing this problem. if repairing will cost you alot then i suggest that you have to buy a new tv insted of repairing your old tv. hope that helps!

SOURCE: have a Pioneer pro elite
Your power supply board is 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.
Hoping this will help in solving the problem....

the problem with pioneer projection tvs is that when they made the boards they never used enough solder for the circuits and you get cracks in the runs. thats why heat and cold will effect it. I had the same problem and I took out the board and resoldered every track I could and it works good now but my remote wont work if anyone has any info or prints to this tv please post on here
