20 Most Recent Sony FD Trinitron WEGA KV-34HS510 34" TV Questions & Answers


These 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. http://electronicshelponline.blogspot.com/

THIS IS NORMALY CAPACITORS IN THE POWER SUPPLY THAT NEED REPLACING

Dust rarely affects this kind of set---this model had high voltage problems---and if popping I would unplug it.

To be honest this set weighs a ton and is expensive to fix, average repair can be well over 200 dollars.


A lot of them now are being retired and replaced with LCD sets etc.

Are your headphones blutooth or infra-red? Is your Trinitron Blutooth or infrared enabled to allow you to listen to it thru your headphones? If so, there must be an on/off switch that would actuate the Blutooth or infrared meachanism on the Trinitron itself. Otherwise, you WON'T be able to hear sound.

1) the main problem is lack of Raster
2) see the block diagram, test Video Detector, the transformer or flyback, horizontal output transistor, rectifier HV,,

Check the video output section circuit for any loose soldering or component failure. Check the voltage at the green cathode of the picture tube. Can be measured by using a multimeter. At present, this voltage will be lower than other tow cathode voltages. In most cases, the cause for this fault is found to be with loose solder terminals itself.
Check all the solder terminals at the video output stage printed circuit board. You can locate this board at the picture tube base itself. Will be plugged to the back of the picture tube neck. A rectangular board. Normally, it will be very difficult to detect loose solder points, as they might be microscopically small to detect by ***** eye. So it is recommended to re solder all the suspected solder terminals there, by applying little more fresh solder, without making any solder bridge short in between adjacent solder terminals. This must solve the problem you faces with your TV

if no any power light indicator that blinks or lit, the cause it could be the primary power supply failed or the horizontal deflection circuit has shorted component. you must need to trouble shoot those circuit to fix the problem. however if you think you can not do it with your own, just leave it to the trained tv technician. at least you have an idea what to expect when you decide to hire for somebody to fix the problem.hope this can helped.

The set may have a self check mode or error buffer--most of these that do with the set turned off: Display, 5, vol. down and then power.

If it has the buffer a box will appear in middle of screen with several items listed-----------all should have a 0 to the right of them---a number indicates a error detected and noted.

If no error found or no display for that contact Sony for the reset code which usually is gained by going into tech menu (different from error menu) and with remote pressing 7 and enter---this does a hard reset and returns set to all factory defaults--if that did not cure it you have a interesting trouble...........

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as 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. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit from TvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

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.

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 TvRepairKits.com . It includes replacement coolant,step by step instructions, support, etc.

replace two chips, cost you about $10.00

Sony FD... | Answered on Jul 11, 2011


I would question that diagnosis, Did you get it online somewhere or did you have a tech check your B+ voltages ?
6 blinks is almost always caused by 2 chips on the "D board", they are both marked MCZ3001D you can order them here if you are a consumer not a tech 800-575-9833. Not to say that the jungle IC & those 2 caps couldn`t cause a dead set symptom but these 2 IC`s are notorious for the 6 blink code, I have personally fixed approx. 10 sony sets with the 6 blink code with those IC`s, hope this helps

Sony FD... | Answered on Jul 11, 2011


HI:
Count the number of red blinks on the power led, if it is 6 or 7 blinks then pauses and then does the same amount of blinks then ther is a problem with 2 IC's that needs replacing on the D board. To repair this including parts should not cost more then $150.00.

Sony FD... | Answered on Jul 05, 2011


The Standby light flashing that you see is the built in diagnostic program signalling an issue. This particular one means that the D board is not getting the 15 volts it needs, and normally IC5004 is causing the issue. It has been awhile since I dealt with this repair and I therefore have no idea what it will cost you to have it resolved.

If you have some experience working with TV's you might want to take a run at fixing the issue. You would have to ensure you have the tools you need as well as a copy of the service manual, which you can purchase or download of the Internet. I would not advise trying the repair yourself if you have no experience with the inside of a TV. There are lethal voltages and amps inside that must be dealt with in the correct way so that it is safe to work inside the TV.

I would suggest calling your area Sony repair shops, let them know what the flashing code is and what it is signifying, and then asking them for a quote to fix the issue. As most electronic repair center charge from $85-125.00 an hour for labor I would get an estimate and then decide if it is worth fixing, or would it be less expensive to buy a new TV.
