If there's any warranty on it then I would grab it quick sharp
The panel will be nice and settled with around 900 hours on it, nothing to worry about at all.

1 year warranty on it. One of the last few at richer sounds if I get it home and there is burn in on the screen would I be able to take it back?

How can I check how many hours the set has had on it?

Check it with a white screen. Ofcourse any burn maybe just IR

You could use my freebie KuroTIME program here:
KuroTIMEsetup.exe - 4shared.com - online file sharing and storage - download
However, you really do need to use a PC with a dedicated 9 pin RS-232 port.
It does support some USB/serial adaptors but not all.
Also you need the correct serial cable to connnect to the TV. (not null modem)

I picked it up yesterday and its the best TV I have ever seen I can not fault it far improved over the V20. I will run the hours check this morning just out of interest.

I bought one of these from this ebayer
USB 2.0 to 9 pin RS232 COM Port Serial Adapter on eBay (end time 22-Jun-10 11:18:20 BST)
Please note I have no connection with this ebayer and I can't guarantee they are selling the same adaptor that I bought.
However, it looks identical in the picture

Assuming this RS232 adapter works, would you just plug the adapter into the 5090, run a USB extension cable from the adapter to a PC, then open the KuroTIMEsetup.exe program to automatically see hours ?

Sadly no...
You also need a gender changer adaptor or a serial cable with sockets at each end.
This is because Pioneer put a 9W plug connector on the back of the TV and the USB/serial adaptor is also a plug.
So you need a 9 way skt/skt serial adaptor. (AKA gender changer)
Just to complicate things, you need to avoid NULL MODEM cables as these appear to be exactly what you need (SKT to SKT cable) but they have a pin swap on pins 2 and 3 so this type of cable won't work.

Thanks for the info Chelsea Fan.
OK, so thats a serial cable (skt/skt) from the USB/Serial adapter (plugged into the PC) straight to the back of the 5090 ! Then, run the Kuro.exe program......
Can I assume that the KuroTIME program does not put a "flag" on the 5090's eeprom to show that the service menu has been accessed and therefore invalidates any outstanding warranty.

It doesn't need to access service mode to get this data
There's a whole load of RS-232 commands that can be sent to the TV without needing service mode including the ISFccc interface. You can also control the TV as if you were using the remote control. i.e. call up the usual onscreen menus and change channel or volume etc etc. The info to do all this is on the Pioneer website.
Service mode access requires a separate command and this unlocks loads more commands but no one really needs access to these.
The only possible exception is the grey sidemask control for 4:3 content. In order to change these to black you need to access service mode first.
I haven't released any freebie programs to allow sidebar adjustment for that very reason. i.e. the TV has to be put in service mode first.
I'm not convinced the warranty would be automatically invalidated anyway and I would be more concerned that people would want to explore service mode and end up adjusting stuff that should be left alone.

judethedude did you get it to work?

I'm still waiting to find out !
I bought a USB/Serial adapter (the one on eBay linked earlier in this thread) and an RS232 cable. However, when I tried to plug the cable in to my LX5090 I found that the TV wall bracket partially obscured the service connector on the back of the TV.
I have therefore ordered a Right Angle DB9 to DB9 Serial Cable Adaptor which, I hope, will solve the problem and enable me to access the TV hours menu.
I should receive the adapter within the next few days so I'll let you know how I get on.

Whoops sorry for the late responses as I didn't flag this thread.
If the SW can't see the COM port then any of the following could be wrong.
1/ The 9 way serial cable is incorrect. Can you remove it and bleep test it to make sure that
pin 2 goes to pin 2
pin 3 goes to pin 3
pin 5 goes to pin 5
i.e. check that it is not a NULL MODEM cable.
2/ Your PC has assigned your USB/Serial COM port a higher value than 16. Can you check this in Windows Device manager? You can change it to a lower number but it is a bit fiddly.
My software only works with COM port 1 to 16.
3/ The TV isn't set to the default serial Baud rate of 9600 bps.
You can check and change this (if necessary) in the TV's INTEGRATOR menu.
4/ Your USB/Serial adaptor (if you are using one) isn't compatible with the drivers used in my SW
Hope this is useful

The best thing is to go on the Pioneer website and navigate to whatever TV/appliance you require.
eg try this link
Pioneer USA - RS-232 Codes
Otherwise just google
RS-232 Pioneer
and you will find loads of direct links to generic RS-232 codes.
You can also get model specific RS-232 codes in the relevant Service Manual. Eg I obtained the service manual for the LX-5090 to get the codes for my TV.
There are other Pioneer docs on their website that aren't as easy to find. i.e. I think they are blocked from the usual online navigation. I had to resort to some sneaky methods to gain access to them ;-)

how do you do a bleep test with the 9 pin cable
Chelsea_Fan
Established Member
Sorry for any confusion, I just mean test it for continuity with a circuit tester. eg check that
pin 2 connects to pin 2
pin 3 connects to pin 3
pin 5 connects to pin 5
Some continuity checkers also make a bleep noise to speed up the testing. Hence 'bleep test'
