20 Most Recent Sony KP-53V80 53" Rear Projection Television - Page 2 Questions & Answers

The problem you are having with your Sony KP53V80 is called convergence. The good news is that your set comes with a feature called Flash Focus, which is designed to correct convergence more or less automatically. The bad news is that if this automatic procedure has no effect, then you have failing/failed solid state components inside the unit that will need to be discovered and replaced, a job for a qualified tech.

Follow these steps to perform Flash Focus for your set:

1. Press the MENU button
2. Use the joystick to select SETUP
3. Use the joystick to select FLASHFOCUS

A cross pattern will appear while the adjustment is working. When the cross turns white, the adjustment is complete. Pressing any button while the adjustment is being made will terminate the adjustment procedure.

I hope that helps.

Projection TV sets have several common problems listed below.

Problem #1) Convergence

Symptoms:

• Screen Looks 3-D
• Colors wont align
• Screen may look distorted
• No Audio/Video - makes a chirping sound.

Usually in the back part of the manual are instructions on how to reset it.

There may be an open fuse. The typical fuse for the application is a 3-amp, and may not look anything like your typical fuse. If you have sucessfully replaced the parts that you indicated, the convergence should be very close to what it was before the failure. The fuse may look like a small rectangle of black or white plastic with a wire through it.

Hi


Thanks for using FixYa. Heat is the number one enemy of electronics, and these sets operate hot. This problem is caused by the power supply being overloaded. This is often caused by failed convergence ICs. I don’t think the issue is with the power supply of the unit as the sound is coming fine from the unit. This model of TV has over 3,000 parts which include millions of transistors inside the integrated circuits. Over time the capacitors will change value, leak and become defective. Resistors will change value and burn. This will cause other components to become defective. This can has a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The typical cost to get this fixed by a pro is about $300 - and it doesn't mean that he/they will do a job better than you do. The parts are less than $100 (about $20-$30 for the IC's) if you want to do it yourself. Replacing only the IC's MAY solve the problem; however, many people have also had blown resistors requiring replacement. Why would you ask should you replace both of the IC's if only one is shot?! If one is shot the other one is not far away and for that little price of the chips it worth changing them both at the same time. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice.


Please do accept the solution if the issue is resolved or else revert for further assistance.

its protecting ... the system just detected some other problems 2 ur system or power supply.. modern television has an auto shutdown protector circuit... i just said whwt i know... tnx

This set has 3 screens---the outer one is really only for glare--clear plexigalss--no longer available from Sony.

Sony 4-070-602-01
SCREEN, FRESNEL Sony 4-064-343-11
SCREEN, LENTICULAR Sony 4-058-894-11
SCREEN, PROTECTION (CONTRAST)Outer one is (Contrast) the other two inner ones are showing as available and about 180 each.

You would have to either have someone dismantle or do it yourself---most of these sets you have to remove all three screens from the rear of the set---then remove the outer contrast one if it is scratched or cracked--

If you get it out and measure it: It is possible you may be able to find a company who can cut you a plexi-glass piece to replace it with--lots of work to do this and you have to use extreme care when you remove the two inner screens--easy to damage them---Usually the inner two are taped along all the edges to keep dust etc from getting between them and the front one is a short distance forward of them.

The front protective screen is really only there for glare and to protect the inner screens from damage---I have seen people who had a cracked outer one just dismantle and remove that one---put the others back and use the set that way---have to be careful as the inner screens are easy to scratch or damage with the outer one removed.

Also---I have seen several where someone removed the outer one and got a piece of plexi glass big enough to put on the outside of the front of the set---secured all around the edges with velcro--does not look as good as the original but prevents glare and protects the inner screens.

YOU LOST VERTICAL DEFLECTION THIS WILL REQUIRE PARTS REPLACEMENT

Sounds like a faulty capacitor in the unit. The only problem is knowing which one it is. We usually use an ohmmeter in the ohm setting and check the resistance of each cap. If you find one with very low or no reading, that is the bad one.

First unplug the DVD and plug the satellite in the place where the dvd was. if you get sound the problem is with that particular TV input or the wiring if you get no sound the problem is with satellite. Check the sub volume for the Satellite or call satellite provider for assistance

Replace Both of your convergence ICs They are big black ICswill have part number on them STK392-110 Order the same # as your STKs have on them Call Mats for Parts 1-800-628-1118 also CK pico Fuses they look like resistors will be green or yellow they are fuses.

I removed about 6 or so screws took back cover off and used a duster to clean the inside screen it cured my cobweb problem.

Easy way to deal with this is to unplug set and remove back cover-----with one of the Swiffer type dusters(there should be plenty of room inside this set) gently reach up and get all the webs out---also a good idea if you do this with a lens cloth or paper towel with windex clean the three large black lens you will see when you remove the cover---they usually need to be cleaned about once a year(if they are dusty the picture will be darker and not a clear)

If this has been helpful give me a vote here.

Shorted hori output transistor and bad 1200pf 2k volt capacitor.

What input (any or all) does this happen on? If it is an SVHS input, reseat the SVHS connector... The SVHS connector separates the Chrominance (color) from the Luminance (b&w), so it may be as simple as a new connector or re-seating the existing connector.

If it happens on ALL sources, then a similar situation may be occuring internal to the television itself. Re-seat any ribbon cable connectors, molex connectors et Al.

The repair tech used cheap parts or did not replace both convergence chips.


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.

When you first turn it on,Count the flashes on the standby/power button.

Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground,or held high), IK video path is defective.

Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.

Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This isalso a problem in the power supply circuit, check T603 and R672.

Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted.Check IC1509, Q1505

Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on
the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.

Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits
.
Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback
transformer), or the associative components in the high voltage circuits are defective on the D board.

Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times
you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negitive).

Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors
are bad, check R8051 and IC8005, also on the "D" board

You can clean the screen from the back - take off the access panel. I clean mine once a year whether it needs it or not.
