Old Sony · Joined: 19 Feb 2008 Posts: 12

I'm really not anywhere near the league of most of the set ups posted here! Embarassed

But I was wondering what maintenance the gurus might prescribe for My Old Sony. I've never done anything with except the flash focus since I've Had It. Or maybe the suggestion might be don't bother.

Not that I'm having any noticable problems with it, but do the tubes need regular cleaning or other things such as that? I bought it new around 2000. I might not be looking in the right posts but didn't see anything on RPTV maintenance exactly.

Here's what I'm using by the way.
Motorola DCT6416 III hidef cable box
Phillips DVP 3960 up convert Dvd
(Add Pioneer Elite VSX 94-TXH)
HD fury Gamer
Steren 1 foot vga to Rgbhv rca
Sony kp-61hs10
(Was using component but switched to Fury for HDMI)

Thanks for any direction ahead of time!

While I don't know anything about your particular model, there are a view things that apply to all rptvs. First, if you have been using it in a dusty area, or if it is fan cooled, then it may be helpful to clean the lenses if they are dusty. If the lenses seem overly dirty, you might want to check the mirror and tube faces as well. (however I recently went to clean my 1995 rptv for the first time, and it didn't need it.)

More importantly, you should getting a hold of a calibration DVD, and do some touchup convergence, and calibration of all settings that are available to you. Is there service menu/ do you know how to get into it?

RPTV's pick up all sort's of dust and grease in the air. The tube faces, the lenses ( especially since they aim upward ) and the mirror in the back of the cabinet are the 3 main part's to clean. However you don't just start spraying Windex in there. ( never windex )
Here's the proper formula for the lens cleaner: http://www.curtpalme.com/Lens_Cleaning.shtm

Along with cleaning the optical path you can also clean out the dust on the electronic's. Use a 1" paint brush and some lint free towels.
Remember to unplug the TV from the AC power 30 minutes before servicing. Then hit the front power button once to release any pent up charge in the set.

Make notes, use a video camera, shoot Polaroids ( of the TV not your wife Wink

) or grab a cheap digital camera. Take lot's of pictures so if you do have to take anything apart you'll know how to put it back together.

After you have it all cleaned up and if the hours are not too high on the tubes ( should be listed in the service menu ). You may want to consider a calibration. Either learn to do it yourself of ask around to find someone close by that has a coloromiter and a few hours to spare. You could even hire a profesional ISF guy to properly calibrate your set. It makes a world of difference.

Good luck.

i have a sony kp57ws500 a little newer than yours but they
are probably equal units.
i clean my dust out once a year and the lenses as needed
mine is liquid coupled as are most rptv so no dust gets on
the tube face but the glycol can get nasty (easily changed)
i am including a link to the info i used for my sony and it will
probably work for yours just be careful and read read read
before you start
i can get mine to the point where hd can look almost 3d

very helpful the convergence is in this service menu and
and it can make a huge difference over the flash focus
