I have to know old sony trinitron kv hw21m83 introducing year

Id you have no TV repair experience, play it safe and take the set into an authorized Sony repair place to estimate the cost to repair. Yes I know it would be nice to repair, but how much do you know about component level printed circuit board repair? You will need to first get a service manual, know how to read a circuit diagram, thats a schematic, and know how every circuit works with each other to make the TV set operate. I do appriciate the fact you would like to repair this yourself, but there is no magic fix in most cases when it comes to electronics. There is circuit diagnosise involved. Best advice would be to call in a pro to assist you in these types of repairs. Good Luck

The 2 blinks usually mea an over current problem. Perhaps the most common cause of this is a shortde Horizontal Output Transistor (HOT). If you can solder, you should be able to repair this yourself. Realize that there are potentially dangerous high voltages present inside the set even when unplugged. Look for a 3-legged ransistor attached to a heatsink close to the flyback (part with large red wire coming out the top). The part will be marked C5438 or something similar. Post that marking here nad I'll confirm the entire part number.

Keep us posted.

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.

ONE: Unplug it for at least 4 hours. That is what we call a hard reset.

TWO: If the hard reset does not help, then it will need further diagnostics.

The following bulletin may be of help in your learning about what is going on. Please refer to it below. Then let me know if you need further assistance.

Have a great day,

Sony Blinking Codes
Many of the later model Sony TV's have a built in Self- Diagnosis function. If
the timer/standby indicator is blinking, this could be an indication of the
problem with the unit. The diagnostic blinking will occur automatically with no
action required by you to engage it.
The timing of the blinking you see would be as follows: two to eight blinks
(depending on the fault) about a third of a second apart, then pauses for 3
seconds, then the two to eight blinks about a third of a second apart again.
Here is a list of the problems that might have occurred indicated by the
number of blinks. The words in parentheses are those which you will see for
each of these faults on a diagnosis screen described later in this article.
Unit is dead and there are no blinks---Problem in the standby power
section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should
show open)
Continuous Blink Once A Second, No Pausing As Discussed Above---
No reply from the jungle IC301 (data bus is busy, shorted to ground or held
high), IK video path is defective.
ONE Blink--- not used for the self-diagnosis
TWO Blinks---B+ over current protection (OCP) , unit goes to the standby
mode then displays the 2 blink fault. Could be a short in the power supply of
any of the circuits.
THREE Blinks---B+ over voltage protection (OVP), unit goes to the standby
mode then displays the 3 blink fault. This is also a problem in the power
supply circuit, check T603 and R672.
FOUR Blinks---No Vert. Deflection (V STOP), Screen goes to a single
horizontal line then the video signal muted. Check IC1509, Q1505
FIVE Blinks---AKB circuit (AKB), the timer/standby indicator blinks for about
30 seconds then goes to the self-diagnosis function. Something is wrong with
the video. Check video out, Q705, 732, 761 and other components on the C
board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking,
try turning up screen slightly.
SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking selfdiagnosis
function immediately. Check C515 & 516 and the jungle IC, IC206.
SEVEN Blinks---High voltage shutdown. The high voltage has exceeded 33k
and the unit goes immediately into safety shutdown. Check power supply
regulation and horizontal circuits.
EIGHT Blinks---Problem with the audio (AUDIO), unit goes to standby and
blinks the self-diagnosis code. Check IC406 audio amp, PS401 and 402.
Intermittent problems ?? This is a great feature. You can also bring up
these fault codes ON-SCREEN to see a list of the problem numbers with the
abbreviation of the problem and the number of times this problem has
occurred. This is slightly different than entering the service mode. To see the
diagnostic screen, Press the following buttons:
Display, Channel, 5, Vol Minus, ( Not plus ) then Power. This brings up
a screen with a list of the problems and number of times they have occurred.
Each of the problem names is abbreviated as, "OCP", "OVP", "V STOP", ETC.
We have repeated them in parentheses in the text for the "Blinks" described
above so you can correlate between the diagnostic screen and the blink
codes.
So, now that you know about these self-diagnostics, how do you use them?
Say that you have a set with a black screen. You see that the LED is blinking
4 times....This would tell you that you have no vertical and that is why the
video is muted. If it was blinking 6 times, you would know that you have a
horizontal fault.
It's not a sure cure, but it's a little better than a poke in the eye with a sharp
stick.
IMPORTANT: after you repair the unit, PLEASE clear the values on this
diagnostic screen. These codes do not reset themselves after the fault is
corrected, so if you don't clear them, you'll be seeing "old" fault codes the
next time you enter this screen.
Clearing is done by going into the service mode ( display, channel, 5,
volume plus, then power ) then press 8 and Enter, which of course returns
everything to the factory preset condition.
