Top 20 Sony FD Trinitron WEGA KV-32HS500 32" 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/ Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty. Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any.

Check the audio settings. Whether it is muted or volume is at '0' stage. Check the speakers. Check the audio output section circuit.

bad heating filament.

the high voltage was shutdown the high voltage exceed to 33k volt which goes to safety mode.you will need to check the regulator in the power supply and the horizontal output transistor.

bad picture tube , new tv

Check this link to download the user manual to your Sony TV. It has all details, with illustrations.

It sounds like its in video mode to me if it actually did turn on. Press the video button 1 -7 times until it cycles to your screen. (manually press the video button on the front and just below your tv).

propably green not working. due to age its hard decision its worth or not to repair, but i recommend to sell for a few bucks to a hobby-freak and buy a new one...

This is a fault solution which can be checked and corrected by you assuming that there is no component failure. There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance.

The best way to check for loose connections is to tap lightly when the set is powered on , If there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points.

Sometimes the fault occurs when the set warms up, if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault.

Based on the above method you must be able to locate the area of fault and solder the sections. Sometimes large IC's- ones with more pins- tend to have drying in some pins and so cause faults related to the IC's protocol. Have a rough idea of looking into the areas to reduce the time of probing.

Check for tips to look into the SMPS unit with some of my tips:

Thank you for using Fixya.

hi,
Blinking led in sony tv is its self dioganising function. 7 blinks by it means the horizontal output voltage increased above 33k.
You have to check the power supply stage of you tv. Normally in sony tv dry soldering can happend in the power supply stage. It will lead to unregulated voltage output from the power supply. Resolder all the points in the power supply section it will solve your problem.
ok

flashing indicates a power shut down or an overloading occur in the horizontal stage section...have a qualified technician for servicing

well try replacing the h-out power transistor, hope it do the trick. thanks, please rate and vote

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.

On some models 3 blinks pertain to a lamp cover error, lamp cover is not attached securely or lamp is not set securely causing no picture or sound. There are switches or sensors that interlock and send signals to the board telling it is set securely.

The "D" board is the main circuit board assembly containing most of the set's power and deflection circuitry. It's the board that typically causes most of the problems because there's so much on it. Unfortunately, this board is no longer available from Sony as a part, and must be repaired to the component level. Many shops don't want to (or can't) get into that depth of repair, so they quote a high price on board replacement. There is no single part you could order to repair this board yourself, I'm afraid. There are some companies in the business of repairing boards, but you're still looking at $200 to $300. With the price of a 32-inch LCD set now around $300 to $400, there's no point in trying to fix a TV when it's just a few dollars more for replacement.

Hello

Your TVs anode cap is arcing. The sound you hear will be like "Ishhh", and a fouling smell of Ozone also be there from the top back side of your TV.. It will stop after some time, say after 10 or 15 minutes; and picutre will be oke thereafter. You must get it repaired without any delay, otherwise the final anode will get rusted, and will turn the picture tube irreparable.

The final anode of the picture tube is clipped into and is protected by a rubber ******, called anode cap. When the the humidity in atomosphere increses, the arcing also will incresae, and will take much time to get picture to come clear. Anode cap is a replaceable part, even though it is integreated with Line Output Transformer. Proper care must be taken when replacing it, and must be done by a well experienced technician. Do it atonce as fast as you can, otherwise thigs will go worse. The anode voltage of a 32" tv comes upe to 28,000VDC [28KVDC], so it is dangerous to handle by yoursef, if you are not experienced. The charge at that point will hold over for hours, even after the set is switched off. Anode must be well discharged before handling the anode cap. A well experienced on only can do this. Do it without any delay I advice you. OK.

Hello
Blinking of standby light on Sony TVs are fault symptoms. You just count the number of blinks exactly and keely, for switiching the tv with its FRONT PANEL POWER ON-OFF SWITCH; and not by the remote control hanset. Do it for atleast three times, and confirm the number of blinks, and inform me through Fixya. OK.

Sounds either like you have cold solder joints on the power supply board that after the set has been on for some time these connections heat up and lose contact...or it may be the power supply itself is heating up and going bad..causing the set to shut down. If you can solder...open the unit up and look at the bottom of the board...the solder connections should be clean and shiny..if they look like they have cracks around the pins of the components then they will need to be resoldered to resore the proper functioning of the set...if soldering doesn't help, then you will need to have it serviced at a shop

Hello
Seven blinks in Sony sets denotes there is some trouble in the power regulation system inside the TV. It is called High Voltage Shutdown. When the power regulator inside the tv supplies excess voltage more than normal, to the circuit board, due to some fault, the Extra High Tension voltage that goes to the final anode of the picture tube will exceed 33KV [33,000VDC], and the main system control Ic inside it it is so programmed to detect this state, and shuts the whole system in power off stage, and give indication through the LED on the front panel.
Normally most of the Sony TVs power regulator system is STR based, constant high accuracy regulation system. The STR said above will heat up to 75 degree C during working. Repeated heating and cooling may make the solderings at its legs to circut board, to get loose contacted. In most cases this was the fault I experienced. To rectify this fault, you have to open your TV.
If you are doing it by yourself, take all precautions we have to take before working with an electrical equipment. Never allow chlldren by your side, or not allow them even stand beside you. Be an adult beside you when you works, and he can assist you.
As high as 31,000VDC points are there inside your TV, while its is working, you must be vary caucious. Locate the power supply regulator section. It can be recoganiszed by following the AC input wire, which is connected to that section. There will be the power regulator, said above, screwed into a metal plate. Just pull out the board, take it uside down and examine for any loose soldering are there to the leg solderings to the STR. It is very difficult ot locate the loose contacts, as we do is resolder all the suspected points by applying a little more solder. In most cases this will solve the problem.The secondary regulated voltage in most 32" tvs come upto 135VDC. Check that voltage first, and then proceed.
Power supply regulatior board inside your TV has the problem. So concentrate on it very carefully. It is not an isolated section, that is it is always connected to the main supply, so be carefull when working with it. ok.
