How many times the standby button blinks before going OFF at one time switch ON?

Check the tuner. Check all supply voltages to it. It is a skilled job. If all voltages are OK, replace the tuner.

Hello mvadima11,Welcome, and thank you for using FixYa!To answer your question: The white balance isn't the issue on this set, in my opinion.I would be more inclined to believe that someone had placed a speaker or large magnet too close to your television.If you have speakers right next to the set, move them away. If someone set a magnet on the set sometime recently, you will have to rebalance the tube.To try rebalance of the tube, find the largest magnet you can find. Then starting from the outside edge of the tube, go in clock-wise circles, slowly, all the way to the center of the television. Once you have arched the center, pull slowly, straight out. Now turn your color back up to normal. This should fix your issue.Have a great day!

What seems to be your problem?

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.

sound like fly back transformer is acting up or screen voltage is abnormal.

Hi,
I can provide you required info, can you replace parts in circuit board that requires soldering work.
Thanks.

If TV model is Sony KV-32HS420 then mostly it requires to replace 2 ICs on DZ board, let me know if you can replace ICs on circuit board and know about TV repair to provide you more technical info.
Thanks.

Hi mtennant6wv,

This is an indication of out-of-regulation in the power supply section. The very common caused of this fault is the leaky electrolytic capacitor in that section. It will drop the supply from normal voltage and will disable the unit.It needs a little warm-up to make itself stable but the symptom will get worst. Sometimes it has a bulged/dome at the top but not all, it is better that you have a capacitor checker/tester to determine its condition. Your unit will back to normal again if the leaky capacitor is isolated.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.

Also check if your unit is under warranty /extended warranty, avail it because the manufacturer of your unit will fix it for free. Don't open the back panel, this will void the warranty.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

Overcurrent protection mode - this is usually a horizontal output failure, best bet is to check the flyback transformer, the horizontal transistor(s) and the tuning capacitors in their collector circuit as one or more may have dropped in value - giving rise to the protection. Either way it's a high voltage failure. I would recommend also checking the power supply - to be sure there are no shorts or blown components there as well.

Better to be safe than sorry. Repair could be expensive, but you won't know unless you submit the TV to a service centre (preferably authorised Sony agents) for a free quote, then you can decide after that if it's worth spending the dollars on.

The blinking standby LED usually is an error code - indicating possible overcurrent protection mode. It can be either a short-circuit in the power supply, the HT rail, or the horizontal output transistor(s) could be shorted along with the flyback transformer. Or it could be a combination of all of the above.

Assuming this is a model with a CRT, I doubt it would be the 'bulb' - it would most likely be a circuit failure. Check the flyback transformer, the horizontal transistors and the tuning capacitors in their collector circuit - one may be shot.

Check the power supply and HT thoroughly for shorts and open circuit components - burn marks on the board, dry solder joints etc. Look for obvious things first.

Once you are satisfied that one or more parts have shorted, and you don't wish to replace them yourself, submit the TV to a repair store and insist on a FREE quote - this way, you can then decide if you want to pay that estimate to fix it or not.

Sounds like a diode may have burnt up or if your really lucky it might just be the fuse.!!! You might want to get a secound opinion .But if you know what to look for , which is any component on the motherboard that appears as if had caught fire sader it out amd replace with exact same component which can be ubtained at radio shack.GOOD LUCK TOO YOU!!!!!!!!!

The 7 blinks on this model indicates that the horizontal section of the TV has stopped working. Horizontal Deflection Stopped

Occurs when either:

1) a +B overcurrent is detected (IC5007), or
2) overheating is detected (Thermistor TH5002).

I have the serrvice manual if you need it. Let me know where to send it to.

Hello
Your TV has fault in the oiwer regualtor board. As it is intermittent 9 blinks means some times your TV is gettin on, an other times flashinig. There is some fault to the switching regulator on the "G" borad or its connections.
If you intent to do it by yourself, take all necessary precations when we work with an electrical equipement. Keep children away from you, and never let them even stand beside you. Let an adult beside you before you open its back cover. Pull out the power chord of your TV frm wall socket to isolate it from mains supply. Stand on any non conductive meterial spread on the floor, or wear shoes made of rubber or plastic. Don't use any metal chair.
Normally switching regulatror can be located on the "G" board of Sony sets. Sometimes in your set, the location may be different. Anyway locate the power regulator board. Pull it out, and examine whether there is any loose solderings in it or not, especially to the solder legs of the STR. Resolder its joints and suspected dry soldered joints.
Power on the set. If this does not help, you should replace the STR [Switching Regulator Transistor], fitted on that boar. It will be screwed to a metal heat sink. Unscrew and desolder it out from the board, and go for the same type and number, replace it. Ok
As much as 28KVDC [28,000C volt DC], points are there in your TV while it works. It is dangerous to touch. You must be very caucious.
Wish you sucess.

more loose inside your tv that is a reason for your tv shut off you need to resolder the printed board

HI. I would start by checking the state of the thermal fuse first. Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

Note: It is recommended by most dryer manufacturers to replace a hi-limit thermostat when replacing a thermal fuse.


Now, once you have verified that the fuse is indeed operation, move on the the actual burner assembly.


On the gas valve are one or two coils (solenoids) used to open and close the valve to control the flow of gas. If a coil fails, gas will not flow and the dryer will have no heat.

The easiest way to diagnose a problem in the burner assembly is to observe the burner operation. Remove the small access panel at the bottom, front of the dryer, select a high temperature setting and start the appliance. Watch the burner assembly, shortly after starting the dryer the ignitor should begin to glow. Next you should hear the click of the gas valve coil and a flame should ignite. The flame should be mostly blue and it should remain on for a minute or more.

If the ignitor glows for several seconds (up to 15 seconds) and then goes out, the problem is probably the coils (solenoids). If the ignitor glows and stays on, then the problem is usually the flame sensor. If it ignites and then quickly goes out, it is most likely a problem with inadequate air flow.Test the coil for resistance using a multimeter. Set the multimeter to the ohms setting X10. Place a probe on each terminal. The multimeter should change from a reading of infinity to roughly 1300 ohms (+/- 150 ohms) when the probes touch the terminals. If the reading is infinity or substantially different from 1300 ohms, the solenoid should be replaced.

here this worked on mine read the ansewer part on this page
