Re: pioneer plasma PDP-435PE

Yep them readings roughly match pin outs on service manual

Good. Now what does it say about AC detect? Does it seem right?

(I'm trying to get you to do this yourself, so you learn a bit about the process.)

Re: pioneer plasma PDP-435PE

Have you tried plugging the DVI output on media box into an LCD monitor or another TV?

Ive no other tv available to try dvi cable..all ive got is hdmi ports on other tvs

Re: pioneer plasma PDP-435PE

Have you read the service manual?

Do the voltages roughly correspond to pin outs?

Never serviced one before... wouldn't have a clue.

Was at Robot Club - sorry I couldn't post.

Re: pioneer plasma PDP-435PE

Downloaded schematics for media box & them readings seem to be correct?

After reading quite a few findings about solid green & red lights on this receiver box its pointing towards the trap mode..i dont think my friend has had this opened before as it was heavily coated in dust..is there any other way of getting the tv to turn on without this box?..thx

Re: pioneer plasma PDP-435PE

My brothers got a samsung plasma with a media box..could i try his media box with this tv?..it wouldnt knack up any settings or owt trying this?..thx
My bros isnt a media receiver just a fancy dvd player..doh

Re: pioneer plasma PDP-435PE

On the media box. Use DC volts. Measure with power plugged in.

Try plugging in the DVI output to another monitor, too.

Re: pioneer plasma PDP-435PE

The AC detect on the tv?..if so is it taking a vdc reading from any of the pin outs with AC on the tv psu..thx tom

Re: pioneer plasma PDP-435PE

No idea, just check the AC detect. The key to troubleshooting is to check one thing after another (eliminating possibilities) until you find the fault, not to try random things! The message, after all, is MR-AC, which seems to me to indicate a fault with the power supply.

Re: pioneer plasma PDP-435PE

If i press both tv & receiver box power buttons at same time the tv led is solid red(standby) & receiver both green & red both solid..took measurements from receiver box & voltages seem to be correct on all boards...cant test the leads got no other source to try on..does it sound like tv at fault & not receiver..thx
The AC detect pin being 2.690vdc does that seem to high??

Im thinking maybe this receiver box needs resetting somehow..how easy is it to do & what would i need..thx
Its got 1 of those trap switches..maybe i will give him it bk..thx

Re: pioneer plasma PDP-435PE

Okay one DVI and one PanelLink cable. Fun, custom interfaces.

Check for good supply voltages - 3.3V, 6.5V, 12V, 17V.

Read service manual troubleshooting flowchart... follow all the steps.

Especially check the AC detect signal.

Plug the DVI output into a DVI monitor if you have one available... check if you get video.

If no DVI monitor use a DVI-HDMI cable and plug into a HDMI TV.

Re: pioneer plasma PDP-435PE

Obviously, first step check all supply voltages to media box.

How does the media box connect to TV? Does TV have any inputs on rear, or is it just one IO cable between media box and TV?

I have my own shed, dedicated to TVs...

Its a PDP-R05FE media box connects to tv with 1 cable split in 2..

It is because your pics exceed the restrictions below. Use manage attachments.

I keep getting upload failed when using manage attachments..you guys will have to bear with me on this 1..its all opened up on my bed & wife doing my head in...i need a workshop with a hammock..lol
Gonna get some more pics sorted

Re: pioneer plasma PDP-435PE

Sos for not using manage attachments it wasnt working properly last time..do you only need psu pics for now..thx
