You could replace the CRT tube socket, there is a function for the Focus which might be damaged so that the image is not focused.

I can't comment on the projector, but I can tell you that paper-mounted slide will warp, due to the affects of temperature and humidity. Warped mounts will mess up the auto-focus in any projector.
Good Luck !! Jim

Turn Camera off then On Again


it sound like you have damaged the focus part of the lense i am not to sure if you can replace this part as i have never come across this problem with a camera before but the problem could be either the lense focus has become damaged or it could be that a chip on the board has been damaged without taking the camera apart and looking to see if the lense and lense motors can be replaced or do come out their might even be a way of adjusting the lense once the camera is apart to get it back in focus their is nothing you can do yourself as the equipment will cost a fortune to buy. you would need to test the board and all chips and also im sure if your camera can be adjusted you will also need a special tool to do this. i do know on some of the top end cameras you can adjust the focus from inside the camera to bring it back into view but at the end of the day you need to think is it cheaper to repair or to replace also if you take it in to get repaired you might also get problem sources the spares. but at least you know the screen and memory is working fine so it could just be that it need adjusting it is not worth taking the camera apart yourself as their is an order to undo the screws so as not to warp the board also when you put it back together these need to be done in order and torqued up to the right tension else the board will get warped i suggest you take it into a good camera shop and these will tell you of a repairer in your area im sorry but their is nothing you can do yourself witch isnt much help i know but im sure you just need to get the lense auto focus adjusting this will be cheaper than replacing the whole unit at least they can take the cases off and look at it witch i cant do from here so i am advising you the best i can from where i am sorry cant help you more but im sure other experts will tell you the same answer good luck but choose a good camera shop as you are less likely to gut stung on the price of the parts.............................

We went to auto focus on our tv. It shook wildly the when the picture came back the picture is bent. When looking inside the tv the green and red are being projected bent at the top and bottom. Please...


You need to replace the convergence IC stk392 -110...2 resistors and a fuse. located in the deflection board of your tv and after you can press auto focus and the picture will be normal.

Everyting was working fine, came home and picture would not come on, next day picture comes on but blury. see three colors just not in alinement, tried auto focus did not work, plus image loos curved


KP-53HS30 uses two of the STK-392-560 convergence IC's--if auto focus will not correct one or both are bad--there are also some fuses that protect these parts.

Both chips need to be located (Location numbers in this model are IC8001 and IC8002----they are on identical metal heat sinks side by side.

If depends on if you can do the repair yourself--total parts cost on the internet is less than 25 dollars--you need to be able to get at the chips and also need to be able to unsolder and solder the new ones in--most of the time just the chips need to be replaced---most of these sets have 2 five amp pico fuses on the POWER SUPPLY board that protect them and there may be as many as 5 more fuses on the board with the chips---all are pretty easy to locate and test--like checking any fuse.

Let me know if you have questions or need advice--I am here to help people.

Green Out Of Focus


Your TV most likely a convergence 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 are some photos of convergence problems.

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.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Rear projection tv screen warped


Hi, this TV is repairable and you will have to replace two devices. the first is the Convergence board. this device regulates the convergence of the RGB stream so it can be projected evenly. it works in conjunction with the CRT's and deflection assembly and the Focus pack(module). The second device that will need to be replaced is the Focus pack(module). This module is malfunctioning and is causing the smudges and warped look at this time.

Replace these two devices and it will fix this set. i will post the Part numbers below along with there respective prices as well.

Focus Pack(module).--- Part Number-- BP59-00005A--- $38.95


Convergence Board assembly--Part Number---BP94-00383A---- $165.95

Please rate and god bless:)

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.

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.
