[shelby5041]

hi i found this beautiful older plasma tv in trash

when i power it on

it powers on and then off immediately

you can see the plsama display light up for a fraction of a second and then powers off

led light on front flashes in sequence of 3 when tv powers off and plugged in

i have not taken tv apart yet..just seeing if someone has any ideas what issue could be before i tear it apart

thanks

Check this thread, Post #15 https://www.badcaps.net/forum/showth...+service+guide for the service guide. 3 blinks indicates a X Drive dc-dc error

Thank you did not see a service guide for my model

Re: Pioneer pro 800HDI plasma tv powers on and off immediately

Would x drive issue be the z or x board?

Re: Pioneer pro 800HDI plasma tv powers on and off immediately

I just took back off tv and unplugged power to x board and tv does same thing

Powers on then off immediately

I found a aerv man for pro810hdi

It says 3 green flash shutdown is power decrease of the digital dc to dc converter

Re: Pioneer pro 800HDI plasma tv powers on and off immediately

Here is a screenshot.....where the circled 3 is defines the area where 3 flash code exists

What is the digital video assy?

Re: Pioneer pro 800HDI plasma tv powers on and off immediately

Here is another screenshot...the 3 on left means 3 green flash sequence error

Did you look at that service guide? page 30: G3 PDP433CMX, PDP503CMX, PDP4300, PRO800HDI & PRO1000HDI
What color is the flashing led, Red or Green?

I also posted a link (in post #2) to the thread that has the training manual

Re: Pioneer pro 800HDI plasma tv powers on and off immediately

Which serv guide?

The pro800hdi service manual i found seems to be preety informative but im lost...im sure its very similar to pro800hdi

[shelby5041]

Re: Pioneer pro 800HDI plasma tv powers on and off immediately

I mean the pro810hdi i found

[shelby5041]

Re: Pioneer pro 800HDI plasma tv powers on and off immediately

When i plug tv in the red standby light stays solid

When intry to power on i hear a click and screen lights up for fraction of a second and then tv shuts down but led light is green and flashes continuously in sequence of 3 flashes

Re: Pioneer pro 800HDI plasma tv powers on and off immediately

Flashing green 3 times is DEW_DET, I suspect the tv got wet, there is a moisture sensor on the y drive assy, plug CN2002

[shelby5041]

Re: Pioneer pro 800HDI plasma tv powers on and off immediately

Yeah i just saw that..its diff than the pro810hdi serv manual

And thanks for the serv manual

And yes tv prob is wet...i found it outside lol....

Pretty interesting that it has a sensor like that...this model tv seems pretty sophisticated....its loaded with boards ....

Ill wait few days.....the person i got it from said it wouldnt power on but since it was outside its obviously giving an added error....

Re: Pioneer pro 800HDI plasma tv powers on and off immediately

The tv is in mint condition...i cant believe when i opened the back up all the boards looked brand new...no dust or dirt or anything.....very odd for a tv 13 yrs old....

[shelby5041]

Re: Pioneer pro 800HDI plasma tv powers on and off immediately

Well its not actually a tv its a monitor since it has no tuner in it...

update

i let tv sit for another day to see if condensation error went away and it did

however now tv would not power on at all and i had a 1 green 1 red flash on front now

..serv manual says its a shutdown that disables the power button so i reset it per serv manul by doing some key sequesnce inputs and tv would power on and then off again

i then found out that you can not have the back of tv off and power tv on..there is a switch that needs to be made so i taped the switch down and then powered tv on and the tv powered on and osd menu looks great....

very odd...but im not sure why the person threw it in the trash..i found it in the side of road in the snow...its a beautifl tv and in excellent condition...maybe it has long term issues?? or intermittent??? all i know is it piowers on fine right now

will hook up a dvd player to it and see if it actually functions for a while

Re: Pioneer pro 800HDI plasma tv powers on and off immediately

Good to here it works, It may have had an intermitint fault or the guy was just getting rid of it, who knows... Sometimes when the "trap switch" has been activated you must go through a reset procedure to make the tv/monitor work, It does'nt seem to apply in this case.

Re: Pioneer pro 800HDI plasma tv powers on and off immediately

I had to go through a reset procedure to enable the power button due to back off switch thatbwas triggered when i removed back of tv...the serv manual helped out a lot..without it i would have not known about the back off switch....have never seen that on any other tv i have messed with

But yes tv seems to actually work fine....i cant test since it doesnt have standard rca av inputs....it has some odd looking connectors..and itvdoes have hdmi but my dvd player isnt hdmi so....

Who knows why he threw it in trash but he just,said it didnt work....not sure what that means ....but itbdoes power on and has osd menu

Will test if i ever get a hdmi video source

Maybe the tv got a weird fault and just needed to be reset/cleared?

It was a tv video,store that threw it out in the snow.....lucky i got it before it sat too long in snow and got damaged permanently

Does this plasma have any value?

Re: Pioneer pro 800HDI plasma tv powers on and off immediately

What i can say is that its nice to know the fault blinking codes actually worked and pointed me in the right direction twice.....once during the condensation fault and once on the microprocessor fault
