Hello, i have a planar pdp42bk with problems. When i push the main power switch, the standby light comes on red (never green) and then just turns off 1 second later. The green light on the power supply board also comes on and shuts off at the same time. Any idea what the solution may be?

Re: tv turns off will turn on then off right away
The internal overload sensor is engaging to protect the system. The parts cost to replace the faulty board is about $70 But you need the skills to open the tv and change it I recommend you get a professional to do it More expensive of course but a lot safer.

Power supply in set has a standby the runs 7/24 (all sets do and computers also) and the loss of power when restored may have damaged something there---a fuse is possible and should be looked at first---the Standby provides voltage for the remote to turn main supply and the set on.
There seem to be a problem that is why the television is not coming up and stays stuck on standby mode.
First try to turn on the television using the remote of the television and ensure that the battery of the remote is properly working, you can as well try to push the channel button on the television if the remote does not work.
If it does not come up both by using the remote and pushing the channel button, then it means it is a hardware problem, and that is from inside the unit of the television. Since the standby light comes up, it simply means power is reaching the main panel of the television.
This mainly used to be caused by a faulty or bad capacitor on either the main panel or the power panel of the television.
Check the 15v line that runs through all the boards, left, right and top.. If that has no power, then look on the ysus board (left one) there is a flyback reg (5pin) standard to-220 case surrouded by caps, it does dc to ac conversion, if you dont have the 15v output then the chip is bad. I just did 2 of these that had the same problem.
change the c97,c19 and c16 caps below is where I got mines.
