Pulsating static when using pro logic audio setting

When I use the pro logic setting in audio setup, i get a pulsating static noise that seems to fade in and out every few minutes. It works fine when I go to stadium or rock arena.

Re: Pulsating static when using pro logic audio setting

Replace audio amp? processor board. A filter in the Pro Logic IC is bad and does not detect proper signal cueing for surround panning.

Re: Pulsating static when using pro logic audio setting

There is an audio board that needs to be rebuilt or replaced as this is a common issue with these Hitachi's. It is the surround board.

Generally you can't run ECO or ALTO tubes (less mercury) in fixtures meant for regular Rapid Start/ Preheat tubes. Other than that Old tubes near end of life sometimes do that.

I have no Video, have power and there is a large pulsating sound coming out of the speakers, like a large pounding sound in sbout 5 second intervals.

The most likliest cause is a failed convergence board. Try unplugging the convergence boards wires and then try to power up the set. If it powers up then you know its convergence related. If it doesnt power up its probably a deflection board issue then.

My tv goes blank with sound only.

tough call. from your decription it could be the tubes the pulsating. but if i had it in the shop i wwould first look at the convergence curcuit. the fact that the on screen display come up in colors inidcates convergence problems. you might have multiple component falure there. as for cost it could be diddicult to say. average repairs like this barring piture tube problem at my shop run 200 labor and about 150 parts. this is just for convergence cuircit rpair

Most likely problem is the ACS panel if you have already changed the ICs and resistors.

I have the same set. I solved this by turning off the dynamic contrast or adjusting the contrast and brightness settings down.

Pulsating Picture

Your set might have loose conections ,a few places to check is the horizontal driver transformer and the convergence IC's,they develop loose conections and need to be resoldered,if you are familiar with tv service and soldering is something you could do ,some conectors might get disconected when you flip the board,but if you are not too familiar I would suggest you call for assistance from a servicer.Besides the places I mentioned I am sure the set has other overheated places that need resoldered as well.Let Us know how it goes.
