Question about Sony KP-53S65 53" Rear Projection Television

5 Answers

Need Service Mode instructions for this mode 1998 model!

I have performed the lens cleaning with surgical cotton and alcohol free cleaning fluid. I also used the same products on the mirror. The picture is amazingly brighter now! Like someone put a rejuvenator on the set. This is a 1998 model. Can the image be improved further? The user convergence still shows some overshoot of color on the cross hatch no matter what I do. The service mode instructions,I currently have appear incomplete or I am just not knowledgeable enough to understand what it is I am looking for in the Covergence adjustment nor how its done nor how are you sure its done correctly? I may ultimately call in a ISF Tech to align it and my new Pioneer Pro-1140HD. Though in the meantime. Any suggestions would be appreciated.

    I thought this forum was for Solutions and how too's. Your comments offered none of that and served no purpose other than to bad mouth and cheap shot. This set is in a guest house on my property and it works fine and provides a satisfactory viewable TV for weekly sports enthusiasts. A little TLC will make it satisfactory for some time to come, thank you.

    I'd love to drive a Mercedes 500AMG Twin Turbo 12 cylinder, however practicality is more important than ego in this instance. Being able to put aside childish "I must have now at all cost", is what separates adults from spoiled brats. I do have a $4k HD unitas well and can also give credit and appreciate from whence I came viewing wise, which is more than YOUR response has provided!

    No I have not yet. I have a ISF Tech due to come on 2/9 to calibrate my new Pioneer Elite 1140HD and to align, Repair and generally give this Sony a proper going over. It still performs wonderfully for the most part. Pictue is bright, just that I may have not been as careful as I thought I was when cleaning the lenses & mirror. It owes me nothing since 1998! I'll keep you updated when its completed. Thanks for asking!

    This is to inform all readers that my worse fears were just that - fears! I had the services of an ISF technician on site to calibrate my new Pioneer Pro-1140HD and he offered for a few $ more to check/align/calibrate the Sony RPTV. (Mind you the set was never touched by anyone since it was delivered nearly 10 years ago!) Absolutely nothing wrong that its internal focus couldn't fix so he said. He gave it complete 3 hour servicing and found it badly needed 1)Internal Focus, 2)Internal convergence alignments for every axis, 3)Adjustment for overscan, blooming, 4) plus the usual ISF alignment using, signal generators, Test DVDs, and various test gear including a laptop PC with programs to autotest settings.

    This RPTV is better now than the Day it first arrived in my home. Thank you to all the forum contributors who offered REAL help in solving my issues!

I just did the convergence myself using this site as a guide . I have other problems with the set but the convergence mode is easy to access and adjust. Good luck.

With a set that old, it is unlikely you'll get the convergence that close to perfect anyway. You may even make it worse if you go too far in your adjustments. How you could manage to even watch it after looking at a HD set is beyond me anyhow. I would sell it "as is" and stick with HDTV.

take the back off oh unplug it first and then read the label that says no user serviceable parts inside its kinda like the tag on pillows the three delta lenses can be cleaned with a soft cloth dampened with windex they are an optical grade of plastic like the screen so all those caveats apply if you are really brave you can take the lense assemblies off and clean (gently the concave) portion of the top of the crts they are filled with coolant and should be treated with care if you are really brave use windex on the plate glass mirror if you are nice to your tv it will look real good when you get done it will look even better if you know how to refocus the focus block and the screen controls all the home theater dvds wont make up for zen and the art of projo maintenance

SOURCE: Picture cut off

No adjustment needed on these LCD projection. Your problem is in your setup menu. Your default is now is set ZOOM. That is why the bottom of the picture is cutting off. Go to Menu, setup and screen size or something close to that.

Best regards

SOURCE: Convergence Problem

most likely cause is one of the 3.5 amp picos have blown when the old Ics failed. You can get replacement picos at the following link, and they also have the service manual which will explain how to adjust the colors through the service manual. Here is the link.

Skips when playing CD or DVDs

First try a cd head cleaner. It has to work well enough to ffwd to track 4 or as instructed. If that does not work you need to open the case. Unplug power as the laser can blind you. 5 screws on the back and one each side. Lift the lid from the back to about 30 degrees and pull/ wiggle it off. Use a cotton bud wetted with alcohol (Isopropyl or surgical). You need to wipe the glass lens very very gently. wipe dry with other end of cotton bud. Recover and try.
While covers are off look for bulging capacitors or signs of black overheating.

Sony disc player just hissing not plalying

Hello, i just found one of these decks yesterday with the same problem. The deck loads a disc correctly, but cannot read the TOC (doesnt display the title or track number)
The hissing sound is actually the sound of the laser lens vibrating in a unfocussed manner
The solution: 1.Use a minidisc lens cleaner if available.2.If not, eject the minidisc and open the deck. Take a good look at the laser lens. Is it dusty or seems hazed over (cigarette fumes)? (Mine was)
If yes, clean the laser lens directly with a cotton swab to which you add a drop of isopropylene (100% alcohol) or (2nd best choice) window cleaner.
Take care to not bend of break the recording head (the white and copper arm just above the lens)
use a dry cotton swab to pick up any remaning humidity on the lens.
3. Try again to read a disc. any success? No? try, if available, a pre-recorded disc
any sucess then? Chances are it might work with a pre-recorded disc because of the better reflectivity of these discs.
No luck yet? Doest it read some discs, others not? well, it's time to re-adjust the deck. The service manual is available here: for free. BTW the site is an exellent source of all information available about minidisc.
First let the deck tell you what the problem is! Page 2 explains how to enter the self-diagnosis mode. Enter the Error DP (display) mode. Look at the error history. Most probably you will find the code E06 (as i did) which means Focus error.
The service manual explains how to enter Adjust mode.
Keep an eye on the C1 error 7350= doesnt read correctly 0-50=adjustment ok.
Do C(ontinous)-play checking: 5-6-5 MO error rate check (Page 38)
Perform focus bias adjust (page 41) (5-12) This is a manual adjustment Keep an eye on the C1 error 7350= doesnt read correctly 0-50=adjustment ok.
Keep in mind that you have to adust the setting "A" with the AMS button to obtain C1=220, and "B" turning the AMS button downwards (anti-clockwise) to obtain C1=220 the deck calculates automaticaly the adjustment "C".
Perform autogain control level output adjustment for MO discs
(page 42) (5-15-2)

If this doesn't work, reset the deck to initial settings / Initial setting of adustment settings (page 39).
Perform focus bias adjust (page 41) again (the deck displays the adress and C-1 and ADER errors)
Check if the adjustment is ok with C-play checking 5-6-5
Perform autogain control level output adjustment for MO discs
(page 42) again (5-15-2)

MO-disc= recordable MD

Hopefully you can re-adjust your deck. You don't need any extra tools for this, the deck displays the error rate. In C-play mode, a pre-recorded disc shows nearly always 0 C-1 errors, a recorded disc should not show more than 50 C-1 errors and no ADER errrors.

Of course this is at your own risk. I can only say that i needed about 1 hour to find the setting which worked with different recorded discs.
There is also the Continuous recording mode to check that the error rater during recording stay within tolerance. If you use this mode bear in mind that the disc will be (partially) erased regardless if fully or partially recorded. In test mode there is no safeguard against accidentaly erasing, so use a new disc or one with a recording you don't care to loose.
Simply unplug the deck to exit the service mode.
Check if you can record after adjusting the focus. Check if you can enter a title to the disc. Is the title there when you eject and reload the disc? If yes, you succeded!
Hope this helps!

P.S. Yes, i once was working for Sony as a repair techncian...

Blu ray player will not play any disk. Player stays in "load" mode. Open an close controls do not work. Have unplugged and replug. Player tries to load even without a disk in the player. Wireless...

Try to clean your player with a lens cleaner. Insert the cleaner to the player for 3 minutes or until cleaning process is done. If you don't have lens cleaner use a cotton buds with alcohol to clean the lens. Open the cover of the player and dismantle the upper assembly that protects the player. Using the cotton buds clean it with extra care.

Auto focus doesn't work anymore. I can shoot only in manuel focus mode.

Take off the lens and clean the contacts on the camera body and lens where they meet with a cotton swab lightly dampened with rubbing alcohol.

My autofocus has stopped working even though it was set to AF mode

Try cleaning the contacts on the camera body and the lens where they meet with a cotton swab lightly dampened with rubbing alcohol.

My lg DVD player model rc199h will only play one home made dvd. It will not play the dvd's that we purchased, rent or even the instructional one that came with the unit.

Hi try cleaning the lens.
If the lens is dirty or opaque, the player may read only few media types, for example only recorded DVD-R .
You can first try cleaning the lens with a Cleaner Disk. If that does not work clean the lens with isopropyl alcohol and cotton stubs. Disconnect power and remove top cover to clean the lens directly. Be careful because if you put too much strength and displace the lens pickup you may make things worse.

If all that does not work, the lens pickup must be replaced.

Sometimes does not take pictures using any mode but m(manual)after taking at least one shot at m mode starts working normally.

Clean the contacts on the camera body and the lens where they meet with a cotton swab lightly dampened with rubbing alcohol.

I have a philips magnavox 60 inch model 9p6034c103 dark pic

Sounds like a lamp, but its free to open the back and clean the 3 color lenses and the big mirrior that will be directly behind your head.

Taken from the service manual:

2c) Using denatured alcohol on a cloth made of 100% cotton or a lens cleaning tissue, gently clean the Celement (fisheye) lens, coupler and the CRT faceplate..

Caution: Do not use soap or detergent type substances to clean the coupler and its related assemblies. assemblies must be completely dry prior to reassembly

ALSO: I have heard that a bacteria grows in the color fluid and coats the lenses. the fluid is VERY Poisonous, so please please dont dont clean the inside without research and reading the service manual!!! I've read posts where unknowning people opened them and it poured out.

Manual Library you should find all you need here:

GOOD luck...

Help! My Nikon lens (18-55mm on a D60) has stopped autofocusing even though it was previously problem-free! The lens is set to autofocus but it is still not working.

The first thing to do in this situation is to check that the auto focus assist light is coming on and that both the lens and body are set to auto focus mode.
Assuming the above check out, then check the electrical contacts on the camera. In a dust-free environment, remove the lens and look into the camera body towards the top of the camera. You will see several metal "fingers" which make contact with the lens. Be sure these are clean, free of grime, and not bent. A cotton swab with a small amount of alcohol will do the trick, though a foam swab with lens fluid is probably a bit better.
