Sony Grand WEGA KDP-65WS550 65" Rear Projection HDTV - Answered Questions & Fixed issues

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. https://homenol.blogspot.com/ https://electronicshelponline.blogspot.com/ If blinks continue without any pause, the main board is faulty. Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Hi,
Can you paste snap of distorted picture of tv here to understand what kind of distortion is this.
Thank you.

Hello MikeI don't know what else have you done with your TV. Yet, from the number of blinking code, I do understand that its video out board has the trouble. But, before going forward with you I want to know whether you are aware in electronics and have some experience in serivce TVs, and can follow the schematic diagrams, if I send it to you. If you aren't aware in electronics and cannot follow the circuit diagram of this set, there is no use of going forward. If you are confident, inform me. I'm ready to assist you. OK.

Hi,

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue.
Few examples are given below; some of the issues may be resolved without the need for service.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power problem.
6 blinks: - This indicates that there is some kind of audio problem with your set.
7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
If the issue continues to occur, service may be required.

Thanks for using Fixya.

replace the convergance ic chip on the board below the crt of whtever color is not working

Go into Setup menu and look for speaker settings, make sure "speakers ON" is selected. If you still have a problem, post makes and models of any connected equipment. Hope this helps

First check the Hori output Transistor,then small blue capacitor 2k see if it has a burt hole in it, if they are OK the replace Both STK ICs they are big black ICs and will have Part number on them STK392-110 Mats sales ICs 1-800-628-1118

Hello. I can tell you that the blinking lights are a diagnostic system that help the TV repair man diagnose the problem for servicing. Nine blinks indicates a Panel Module Error or Thermal Error which is a complicated thing to repair if you don't have any television repair experience. My suggestion is you call Sony or a television repairman for service as attempting to repair this on your own without knowledge poses a risk of bodily injury. Wish I had better news for you but I want to tell you the truth. Best of luck to you.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• 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.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some pics of convergence problems.

Common 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.

Hello
Your Sony tv is locked I thinks. Try to reset your TV by the flollowing method.

Unplug your TV from AC mains wall socket, and let it be in that state for about 10 minutes or so. Plug it again, and switch on the TV.
While holding down the "Reset"button on the remote control, press "Power" button on the TV. [The TV will turn itsef off, the back on again]. Release the reset button. [NB: You must hold down the Reset button on the remote control until the proess is over.]
OK.

We have good news and bad news ;)
The bad new is that the four blinks you see usually indicate a failure of the vertical hold circuitry and you will need a diagnostic visit from a technician to figure out exactly which IC or board has gone bad.
The good news is that, if parts are still available for your unit, it's certainly cheaper to repair than to buy a new LCD LED TV, especially one as big as yours.
You should call Sony for the name of repair companies in your area. A diagnostic visit from their rep will usually run about $150 in the US. They'll take that amount off of the total bill if you go forward with the repair. Replacement of the video IC boards run about $250 each in parts, plus the initial $150 labor charge, for a total of $400 for a typical repair. If they can't fix it, you're only out the initial fee.

Hi,
KDP-65WS550 model does not have any "G Board", below image shows board names and location inside this tv, however, there is "G2 board".
Thanks.

hi

it is the problem of cathode ray tube,,or jungle ic in D-board,,replace it..

your problem will be solved thank u..//please rate it

High voltage protection. Either transistor Q8014 04 Q 8013 is shorted along with R8051 on the D board or IC 8005 is defective on the D board. Let me know if you need more assistance

First check the Hori output Transistor,then small blue capacitor 2k see if it has a burt hole in it, if they are OK the replace Both STK ICs they are big black ICs and will have Part number on them STK392-110 Mats sales ICs 1-800-628-1118

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.

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

COUNT THE NUMBER OF RED BLINKS THE TV SHOULD BLINK THEN PAUSE AND BLINK AGAIN. THE NUMBER OF BLINKS WILL INDICATE A POSSIBLE FAILURE.

same here what's the fix

When tv is turned on you can only hear the audio and no picture. It shut off after 10 seconds
