Re: pioneer plasma PDP-435PE
Thanks for the responses. So I guess I first have to find the error in the panel. After that I'll start building the serial device to connect my laptop to the tv. I already planned to use it only trough HDMI. Glad to hear it is possible.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

And the pixels on the panel:

Re: pioneer plasma PDP-435PE
With an programmable logitech remote I was able to get the system in service mode. At least i guess. The receiver gives a clic, the panel led goes to green and a few pixels on the screen (right top corner) light up. Hitting the power button on the remote gives me another click and the led on the panel turns on to red again.
After this I connected the dvi output of the receiver with an dvi-hdmi connector to my TV. When I put the receiver in service mode I get some scrolling blocks on the right side of the screen.

Re: pioneer plasma PDP-435PE
Hello Everybody,
Just purchased myself an PDP-435PE panel with PDP-R05FE receiver. The guy told me the receiver was broken. Not sure if that is correct.
When I connect everything the red led on the panel is burning and the green and red led on the receiver are burning. No flashing of the leds. In one of the manuals I read this means there is something wrong with the receiver. In the manual of the receiver is a table (page 182) which suggests it is in "trap switch operation" I've checked the switch and it works fine.
I've tried...

Re: Lenovo G50-80 Turns on and off within 4-5 seconds
Today I started all over again. Made a nice excel sheet to write down all the values with power button on or off. Sadely I get again different values as before. Therefor I don't trust my equipment anymore. The probes I use are a bit thick and my eyes a bit old ;-). So I have ordered a few special smd "needle" probes and get new reading glasses. Those pins on the mobo are so dammed small hi hi hi.
When I am ready to start again I'll be back. Thanks for all the help!!

Re: Lenovo G50-80 Turns on and off within 4-5 seconds
Ok I have done some checking
PLT_RST is 3.3 v when I push the power button drops to zero when I release it.
EC_RSMRST is always 3.3 volt
VR_RDY gives short pulse of 1 volt when I push the power button directly drops to zero. I'm not shure if the 1 volt is correct. My meter might not be fast enough.
ENABLE (pen 1 on PU908, EC_VR_ON or CPU_VR_ON) same story. Short peak.
Hope you can make something of it.

Re: Lenovo G50-80 Turns on and off within 4-5 seconds
Dr Piernov,
First best wishes for 2018 for you and your family!!
Ok, mobo powerd by the adapter. When I push the powerbutton I get 3.3 volt on SUSP#. When I release it it drops to zero. Syson the same and the 1.35v rail (PL307) also. So when I push the pwr button they have power and when I release it it drops.
I have tried to check VR_ON and VR_REDY but I couldn't find them. They should be on PU901 but where is it?
PCH_PWROK and SYS_PWROK give again 3.3 volt when pwr button is pushed....

Re: Lenovo G50-80 Turns on and off within 4-5 seconds
Ok, had some time tonight. I mesured the next things:
PM_SLP3-4-5# give 3 volt when I push the power button. Just for 2-3 seconds.
VCCRTC gives me 3 volt on PD703
+3VALW_PCH gives 3.3 v on J7
EC_RSMRST# gives 3.3 volt
PBTN_OUT# gives 3.3 volt
PL307 and PL701 give 0 volt on both sides
tried to mesure RTC_RST# on QE3 but couldn't find it on the mobo and I'm not sure how the mesure on the CPU (same for INTVRMEN and SRTC_RST#)
Thanks in advance! and...

Re: Lenovo G50-80 Turns on and off within 4-5 seconds
Made a bigger list now. Measured also the signals Mcplslg123 named. I measured everything three times because I got different readings as in my previous reply:
SYS_POWEROK pin 8 0v
SUS_VCCP pin 34 0v
PBTN_OUT# pin 86 3.3 v
PCH_PRW_EN pin 97 3.3v
PCH_PWROK pin 99 0v
LID_SW pin 109 3.3v
PM_SLP_S3# pin 18 0v
PM_SLP_S4# pin 21 0v
PM_SLP_S5# pin 106 0v
PM_SLP_SUS# pin 87 0v
EC_ON pin 111 3.3v
EC_LID OUT pin...

Re: Lenovo G50-80 Turns on and off within 4-5 seconds
Dear Pearnov,
Thanks for the reply. Just been reading and measuring. I get the following:
1. DPWROK_EC pin 35 --> 3.3 volt
2. PCH_PWR_EN# pin 97 --> 3.3 volt
3. + 3V_PCH couldn't find this one. Q25 has 5 volt on the source and 0 on gate and drain. according to the scheme that is correct because it switches 5VALW to 5VS. So I guess I am missing something here
4. PCH_RSMRST# couldn't find this one. Read page 44 again and again, blow it up to 200% but I guess my eyes are getting...

Re: Lenovo G50-80 Turns on and off within 4-5 seconds
Hi mcplslg123 and Smali,
I've got a simular problem. I have a lenovo G50-80 laptop with ACLU3/ACLU4 UMA NM-A362 rev.1.0 mobo. Whenever I plug on the power the power led starts burning for 4-5 seconds, fan and harddrive make a few turns but then everything dies. Tried al kind of stuf I found on the internet but nothing. So I opened it up. No water damage etc etc. Battery chargers works ok! I have taken the mobo out and I am testing it without ram, wifi, hdd etc etc. Just the mobo and power line. I Have read everything...
