Question about Sony KP-53HS10 TV

I have a convergence problem

The t.v. is a sonykp53hs10 april 2001. problem is although all three lamps work fine. the images do not align properly. ie almost an hour glass shape where you have 3 pix in red green and blue that do not line up so i had a sony authorized rep come out to fix. he said it was the convergence amps stk392-020 were bad so he ordered them up and replaced them. we had also checked the icp's for blown fuses but they all check out fine on main board and the power supply board. picture is still the same. there is power going from the power supply board to the main board but is lost when it gets to the convergence amps. if i remember it should be about 15 v but there is no voltage at either amp. i was hoping for a relatively easy fix but it does not seem probable. is there another chip i should be looking for. i do not have the schematics for the tv, neither did the repair tech how do i get schematics. i do know abit of electronics and can use an ohm and voltage meter well but need to know the path of circuitry. i do not have faith in repair tech as he now wants to send the whole board out for rebuild. if it needs to go out is there a place i can send it that would be affordable or a place i can get another rebuilt board if that is what is wrong. thank you in advance for any help you may send my way -dave

I thought i might need a lamp for my mitsubishi tv--model VS 60607 when my tv is fuzzy when turned on.should i simply replace the lamp or is there something else i should try? thank you!

This TV is a rear projection television and does not have a lamp. It has three CRT color guns (Red, Blue, and Green). You have a convergence issue (the red, blue and green color guns aren't aligned properly) and it doesn't sound like a very big one. You should be able to adjust this through the CONVERGENCE Menu in ADVANCED SETTINGS.
More details can be found in your manual, here. The model number isn't exactly the same but I'm sure the process is identical or really close. The other option would be a bad IC (integrated circuit) for the convergence control. This is unlikely unless your picture looks something like this: captainhawk1_15.jpg

I changed my two IC chips and three resistances on my Hitachi TV to fix color alignments. Now the problems is that yellow and blue double image are seen at the bottom of my screen with no much effect on...

Ur tv still have dead resistors parts,test all 12 resistors parts around the 2 STK convergence ICS and changes some more dead resistors parts or changes all 12 resistors parts for sure.If tv still have the same problems after tested and replaces more resistors parts or all 12 resistors parts.Than some how when u handling and replacing the 2 STK convergence ICS and resoldering the 2 STK covergence ICS u short it out the 2 STK convergence ICS by resoldering without proper grounding ur self not to allow for static electricity to kill the 2 STK convergence ICS or u using a soldering iron to high of a wattage for doing soldering ICS work.

I have a Sony projection TV KP-53HS10. From one

It is most likely the convergence board. Rear projection TVs use three lights to display the image. The image is aligned via the convergence circuit. After many many hours of use the capacitors and resistors on the board lose their tolerances. It is very expensive to repair if you take into account the price for a new TV and the quality of the image you will be getting if you do have it repaired.

Tv out of foucs

These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

Rcs hdtv multiple images

The problem you're having is due to the failure of the convergence amplifier circuit. In that circuit are some components which amplify or control the signals to the dynamic convergence yokes, which line up the red green and blue images to superimpose them over each other to create a proper colour picture. When you get a failure in that circuit, it no longer aligns the images properly, and generally you get what appears to be badly set geometry in multiple colours. In some cases you will also get a problem with the part of the power supply that supplies the convergence amplifiers, or the digicon, which is the digital convergence control module.

Color Alignment

the most common problem when the tv felt is the shadows all over the screen (maybe the tv didnt show it imm but looks like now is there the problem)
second:there is a circuit in the tv that works when the tv turns on every day. prevents the tv showing shadows on the screen.
the answer is this: if that system that prevents shadowing is working then the CRT is broken and say bye to the TV. But if the expert tech can make sure the D' gauss system is not working and can repair it then you get tv back.

Cant get convergence board settings

I suspect that the convergence board may be defective. If the convergence was okay before and then went out, this is a fault and not an adjustment! Adjusting only compounds the fault.
Look up the Sanyo home page on the net, and get their tech support. You can order a new convergence board, and the service manual to start.

It may be more practical for you to let their authorized service rep service the set for you. It is possible that you start buying the parts, and end up needing to troubleshoot for more faults. You will need the proper tools and training to get involved in troubleshooting your set.

Lines, colors, delayed images

Had the same problems.  This was after the a power outage.  Had green vertical and horizontal lines, like a checkered shirt.  But I searched online and found the simplest solution.  Just unplug the power.  And it worked.

Red and green lamps look off center

Intermittant convergence alignment issues are quite common.
Either solder the convergence IC pins or better yet , change out
the IC's with first quality OEM spec or upgrade..............T.
