20 Most Recent Sony KP-53HS30 53" Rear Projection HDTV-Ready Television - Page 9 Questions & Answers

Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Solution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

Solution #2


What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

ok i was looking over your manual for your specific tv it doesnt show that you can program this particular remote for the product listed
my suggestion is go out and by the fancy universal remote since you have the better quality tv universal remotes have a better way of programing everything together
hope this helped

There is a secret service menu to converge the Sony KP53HS30.

Caution: Be careful, there are many settings that can be tampered with. Some may be hard to undo.

Procedure: (use the remote control for these steps unless noted)

1. Turn TV off with System Off (under flap on remote)

2. Press: Display, 5, Volume +, then Power. If successful, service text will appear on the screen.

3. Use 2 & 5 to select the PJE Category.

4. Press 9 to get to fine convergence adjusting.

5. Press 6 several times to get the convergence screen of choice. I like the grid.

6. Use the remote's arrow keys (joystick), move the brackets around until you have found the area to adjust. Press the center of the joystick to change the bracket from white to a color. Use the joystick to adjust the color. Press 3 to change color to adjust. When done, press center of joystick again.

Note: Try to keep the grid even and squared up.

7. Repeat steps 5 and/or 6 for all parts of the screen that need it.

8. Once done, you need to save your settings. Press: Mute, Enter. Then on the TV, press "Flash Focus"

9. Turn off power.

TV is ready to use.

correct, both ICs would be replaced for better performance of TV.

heres a link to where you can get the service manual.

There are products such as VideoSecu PC to TV Presentation Converter. I haven't used them. I'm not sure you are going to get the resolution that you want. A DLP projector does a pretty good job. I know that is not what you are looking for.

Type "PC to TV Converter" in Google. They are about $40 to $60 bucks. Before you buy one, read the reviews.

Hi and welcome to FixYa,

Appreciate the direct "Ask Me".

For any TV model with a CRT or 3 tubes and your description of "red is getting too bright" indicates that the controller transistor or power pack IC for that gun/CRT/tube has shorted. Another possible indicator would be fine diagonal white lines and an overly high contrast.

Often this controller transistor or power pack IC would be heatsinked and located at a squarish PCB (printed circuit board) right at the very small end of the CRT/tube. Corrective action would require replacement.

If the "plastic box with 6 poties" you described would look like the image below, then that would be the Focus/Screen Adjustment for the three tubes.

Unfortunately I do not have a schematic or a service manual hence I could not be more specific. Should you be interested, a service manual is available here.

Good luck and Thank you for using FixYa. Happy Holidays.

Hello,

There is a loss connection in your TV...Try to open the circuit and resoldered all the connection. else if you can not dare to fix at your own then contact nearest service center.

Try first to reset the unit for about 6 hours being unplug from the power outlet and after that plug it back in and check if you still have the same problem,...

As you told big picture freeze is working ,then there could the problem in the main processors which not to able pick video input signal ...If you would like to attempt a DIY, you will need a service manual to guide you. You can find one here:http://servicemanuals.vstore.ca/ which also contains the part number incase you need a new part...

Good luck.....

HI,
No this is not a fuse problem, Audio is OK but video is not present.This shows that problem may occurred in various section like Horizontal section Video procession section But one thing is important that this is due to miner components like Resistance or Capacitor.So,you need not to much worry about it.Just contact any expert nearby.
Thanks

Good Day,
It sounds like your TV is experiencing a convergence problem. You should contact a Sony Authorized Service Center and have them come out to your home and give an estimate before they proceed with the repairs on your 2001, $1,900.00 TV.
Good Luck, big IRISH.

Does it blink a certain amount of blinks pause a second or just blink constantly with no pauses? Let me know it will blink a code if its going into protected shutdown. And it will blink constantly for another reason.

Hi,
    Please don't try to touch them.These are for the adjustment of picture position.If once you disturb them it will not adjust to.So, my again friendly advise is to u that contact any expert.And if u want to do by urself then try when find me online.
  Thanks 

this might possess giving an arm and leg for new screen glass there might be a way to fix it and its a long shot

glass repair for auto mobiles that little filler they use for cracks is what i can suggest off hand
i hope this can be of use

This TV is a projector - not a plasma. I can't see how you would get "burn in" on this set. It should handle an HD picture fine.

I have a Philips Rear Projected TV and the time mine did something similar it ended up costing me $400 NZD to get the main board replaced. Sorry samsunwest, you may have to call in a service agent to take a look. It would be worth your while checking out the warranty for your Sony before you call though as it could possibly be under warranty.
