Open Question

I have a Pioneer PRO-FHD1, it has been giving me a twice blinking red light during start up lately. When I reset the main power button, and restart the TV it works as it is supposed to. It has been happening more often lately. Any help would be greatly appreciated.

SOURCE: plasma turened off and red light flases twice

Red flashing x2 = Panel power supply fault

It would be easier to replace the power board than attempt a repair at component level (dangerous voltages)

SOURCE: Monitor does not sutn on, power button flashes four times fast.

Sorry I know your model number and its a Power Down trouble with the Scan IC's that are in the unit. You need a tech to look at it and he will most likely find a bad Scan IC and it will need to be replaced. This a is a relatively easy fix for him.

I am sorry to hear regarding the problem. Disconnect the power supply for few minutes, say 30 minutes and then turn it ON.If you still do not see any picture, than it is an internal failure and needs repair.

There could be few probabilities.What has happened most likely is your Y or Z sustain board has failed and needs to be replaced; both of these are about the same price to have replaced as well. The average cost of replacement for these is $550-$750+ tax, the repair price, however can vary depending on the part of the country you live in and the shop you call out. Sometimes smaller shops that are less dependable will charge less than the large outfits with big overhead costs. If you have electronic repair experience, and test equipment let me know and we can troubleshoot this together, however if you do not a repairman will be required. These sets are fragile and you MUST know what you are doing when repairing them or damage can be caused to them, or you!
This is an unfortunate problem because these televisions should last a lot longer than they do, however the age of them doesn't seem to affect this problem at all. We do warranty work for most of the major manufactures and I cannot tell you how many 1 week old televisions we have done major repairs on. Also the same problem that might have happened to one person's television at 1 week old might have happened to someone else's at 3 years old. These new sets are a shame to be honest with you, nothing is made the way they used to, or the way they should be for that matter. The average span of time for a new plasma or LCD television to last before its first major problem seems to be anywhere less than 3 years.

I am sorry that I do not have a quick fix or easy answer for you on this one, but this set will require board replacement in order to get it running again. Please let me know if there is anything else I can do for you, I will be happy to assist in any way possible.

All of these boards are board level repair,you need to replace the defective board in order to repair the tv set.

I'm not sure about your electronic or tv repair background,but if you have any,and some equipment(multimeter),you could try to fix this yourself.

The Y sustain board is the one to the left from power supply(from the back).

Check any fuse on this board-if any is open=replace the Y sustain.

Same thing for the Z sustain-the one far to the right from the back)

if no open fuse on any of the Y sustain or Z sustain-then some voltage readings will be necessary to diagnose the defective board.

-Vy,is a voltage on Y board-if is too low,disconnect the Y buffer and check again.I voltage comes back up(around-190V,see the exact value on the panel label),then replace the Y buffer.

If still to low,then replace the Y sustain.

It may seem confusing,but these are the steps for a complete diagnose!

There is a least probability of screen being bad. However, the above causes seems to be the main.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Pioneer Pro-118 won't turn on

Take off back cover. The problem power board is to the right of the board where the power plug feeds into the TV. There is a large white fuse right bend the power plug. With a meter it read ok; about 8 inches deeper into the TV on that board was the resister next to two fuses. My 4 amp 125 volt fuse did not read on my meter. After replacing, it worked fine. Check all three fuses while you're in there.
