Pioneer Pro 700HD picture distortion

I rearranged furniture in my living room, picking up my pro-151fd elite, plugged it in to have no power, tried everything I could think of including an overnight reset. Thought of what could be the common denominator with most of the issues that people have, it's that they picked it up, felt under the front left and turned the tv on. The switch is not labeled, is part of a sqaure protrusion at the very bottom of the tv, 1" to the right of the "Pioneer" label, hope this helps someone who just has a dead tv without the blue flashing lights.

ya u just plug in hd antenna in qam in antenna in cox cable style then scan for chs in tvs menu ok

EITHER you have bad filtor capacitors in 5 & 9 volt circuits or you have bad electrolitic capacitors in vertical circuit. J.D.W.

just wait it, because it is processing the display data

The failure is not on the power supply but the convergence amplifiers STK ICs have the 24 volts shorted.
If that fuse is blowing, de-solder the convergence ICs and put a new fuse to power up the TV; you should see distorted video when the TV powers up and the fuse should not blow.
The service manual migth not help much in this case since the failure is easy to pin point.

Good Luck.

if the tv is more than 10 years old no its not worth replacing the power supply.if its 5 years or newer yes it owuld be worth the money

I am still awaiting someone to give me advice on how to proceed, or where I can go to get help. I have contacted Star Electronics here in Suwanee and the owner, Nafiz came out and took my chassis back to the shop with him. His prices are very reasonable and he is really pleasant to work with. I hope it all works out. Please keep me informed if you have any other suggestions.

Thanks,

i was just working on a set with the same problem .. i found a east west correction curicit with a falty transistor. something in that cuircit has failed.

convergence sys. Usually they use STK ICs in there, replace them.
