I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with
troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one
circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

Sony tv model KV-HA21M80 is having problem front stand by L.E.D is blinking 4 times and stopping

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.

I am experiencing a distortion noise in my sony ha21m80 when i connect a dvd or receiver in the av input

Hi,
Difficult to tell without listening to it, but 2 things spring to mind.

Is the screening on the audio input cable OK?

Is the audio level going into the TV too high and thus overloading the input circuit?

Hope this helps,
Brian.

I THINK YOU MEAN RETRACE LINE. if your tv has retrace line the video amp circuit should be checked its a transistor or in other cases its a IC replace either of them.if its an transistor on circuit voltage measurements shoutld be 2.4 volts from the emitter amd 2.8 volts on the base.can also be a faulty inductor..good luck.if you are not a tech have a tech repair your tv.
