Re: pioneer plasma PDP-435PE

Panasonic GT Series are still made by the old Pioneer chappies!

How long will gases last for screen with it been 2005 model?
Its a very nice looking setup shame freeview not built in to MR box..What sort of money do these go for in used cond..im thinking of making him an offer as its better looking than my nearly fixed LG 42"

Re: pioneer plasma PDP-435PE

Well happy that you have got it going!

Pioneer make mint TV's. Just need to give it a clean up in side and it will be like new

Re: pioneer plasma PDP-435PE

Well ive took dog for a walk & to clear my head cos this set done my head in so far..ive stripped remote down & cleaned with isproponal..plugged everything back together & tried the remote sequence again & BINGO it fired right up
Once in the service mode i dont want to mess any settings up so i set time n date & left it at that...it dosnt have freeview built in so trying with a cheapy 1..I want to do a full factory restore to the set & could do with..thx

Ive sussed it out..what i did if any1 ever comes across this problem..
to enter service mode press display button wait 3secs then left arrow/up arrow/left arrow/right arrow then power button..then in service mode keep pressing mute button till you get to initialize page..then press & hold the display button untill the red led goes out from the MR..
Thx guys n gals for your feedback & help

Re: pioneer plasma PDP-435PE

Better pics of them diodes..also this card thats soldered in has a orange led lit when the set is on..thx..its the card behind the heatsink
Them diodes are measuring good out of circuit

Re: pioneer plasma PDP-435PE

Looks like tipex..when probing diodes etc on this tv psu there is 2 diodes D24&D26 which both measure .032 with a continues beep on diode check function..will i need to pull a leg to retest as all the other diodes measure a reading & OL..thx

Re: pioneer plasma PDP-435PE

What's up with that 4 pin black chip with a mark on it, top right of picture? It looks like an optocoupler but the marking on it looks like damage.

Re: pioneer plasma PDP-435PE

If the signal cable is unplugged the tv should have an orange light and it may flash.

The media boxes with these held up very well and I would suspect the small round signal cable first before taking anything apart.

look for bent pins. also this cable has the audio signals as well.

I have the 50hdt50m version of this tv made by pioneer for Hitachi (2003) with the updated power supply. I would not trade it for anything!

Find out if the tv power supply is an axy-1059. The updated version is an axx-1064 and will be tagged on the aluminum back of the power supply.

Your tv may vary slightly from mine pending the year. There were a few different models that used the media boxes.

Hi cadiman..theres now bent pins on either of the lead ends..heres a pic of tv psu model no..with the tv disconnected from the MR the leds on tv green & red flash together indicating MR unplugged..with the MR plugged in the tv led is red flashing 2 times indicating a problem with MR..all you get from the MR is both power on & standby led both been on together..thx

Re: pioneer plasma PDP-435PE

What is the trap switch? I would think it is actually illegal in many cases for a manufacturer to disable a product if the case is opened unless there is a justified reason e.g. a credit card terminal (anti-tamper), medical device... At the very least, it doesn't make sense: why would they produce a service manual then?!

The trap switch is tripped when the top panel is taken off & if powered on with lid off it disables the MR..when servicing the unit your supposed to tape it down..its not illegal from what ive read its an anti tamper device..something pioneer developed...allot of tv techs are stumped on this when the remote sequence does not work..so i guess im trulely stumped unless any 1 here likes a challenge..anyways fingers crossed this dvi ti hdmi might shed some light..thx

Re: pioneer plasma PDP-435PE

Hi tom..no harddrive or flash memory fella..will leave the set till cable arrives..have you ever come across this trap switch before?..all info on tinternet applies to remote sequence tried this & no good..1 tv tech said solid red & green & MR in some shut down mode??anyways thx 4 info so far mucka

Re: pioneer plasma PDP-435PE

Not necessarily... There are three signals there and at least two are important. One is PD Trigger, the other is AC Detect. PD Trigger makes me thing of a signal that fires when the power supply is about to power down. (Does the box have a HDD or flash memory?) AC Detect performs a similar function.

I would wait for the DVI cable and then if you get a good display I think you can rule out the media box.

Re: pioneer plasma PDP-435PE

Without the ac detect & the standby voltages the other voltages needed wouldnt be present..so because all the voltages are correct on the main pin out im presuming the psu is in working order & the fault maybe lies elswhere in the mr box..am i correct in assuming this?..thx

HDMI to DVI cable?

Re: pioneer plasma PDP-435PE

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.)

I will read over the service manual & see if i can learn owt..thx

Re: pioneer plasma PDP-435PE

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