Hi, on the evaporator panel, you will have a code chart glued to it that shows what is wrong and where to go by how many times the led blinks. Look for this chart and they almost troubleshoot them selves. It may have a open pressure switch, or tripped roll out switch ect., so find this and it will tell you what to do. Let me know and please rate me on this. I know you will be kind. Thank you,

    Hi, just checking in with you. The circuit board that's blinking 4 times is telling you the is a low voltage control that's not working. This chart is there and will tell you. There are about 12 codes so I can't tell you unless I were to look. I know you will be able to do this. Hang in there and check it out.
    Sincerely,

Sony TV set, KV20FS120 BA6 chassis: light blinks, set isn't coming on. Why?


Sony sets like this have a built-in self-diagnostic function.
The blinks of the Standby LED are the self-diagnostic codes.
There may be more than one error. The blinks indicate only the first error.

Unlug the set. Wait 30 seconds.
Prepare to count the number of times the Standby LED blinks.
Plug the set back in. Count the blinks.

2 blinks
  • Diagnostic Item Description: +B overcurrent (OCP)
  • Probable cause:
    • H.OUT (Q506) is shorted. (A Board) (20"/21" models only)
    • RGB Amp (IC1751) is shorted. (CV Board)
  • Detected Symptoms:
    • Power does not come on.
    • Load on power line is shorted.
4 blinks
  • Diagnostic Item Description: I-Prot
  • Probable cause:
    • +13V is not supplied. (A Board)
    • IC545 is faulty. (A Board)
  • Detected Symptoms:
    • Has entered standby state after horizontal raster.
    • Vertical deflection pulse is stopped.
    • Power line is shorted or power supply is stopped
5 Blinks
  • Diagnostic Item Description: IK (AKB)
  • Probable cause:
    • Video OUT (IC545) is faulty. (A Board)
    • IC001 is faulty. (A Board)
    • Screen (G2) is improperly adjusted.
  • Detected Symptoms:
    • No raster is generated.
    • CRT Cathode current detection reference pulse output is small.

The above may be of little help. Your best bet is to download the service manual for the KV20FS120.

According to this article, 6 blinks means "No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206". Depending on your confidence in your abilities to repair it yourself, you might want to contact an authorized service center.

Led power light comes on but screen will not come on.


"Blinks a few times" implies the TV is flashing a fault code at you. If you can find a service manual for your model, count the number of blinks and look it up in the diagnostics section.

However, the most likely problem is a burned-out electrolytic capacitor in the power supply. These are usually easy to identify visually; the top of the can-shaped capacitor should be flat, but may be bulged out and may have brown or black material leaking from the vent scores. The photo below shows a bad capacitor to the right of a good one; both have black plastic sleeves.

If this is the case, replacement capacitors are relatively cheap. However, you should look for the following criteria in choosing a new part:
>Capacitance (uF): same as the original, or 10% higher if the original value is not available
>Voltage: same or higher
>Temperature: Maximum temperature should be same or higher
>Physical size: should fit in the space occupied by the original; if buying a taller unit, make sure it will fit when the back cover is reinstalled, and make sure the capacitor will not touch heat generating parts such as heat sinks, resistors or large transistors.
>Ripple current: get the highest available without compromising too much on endurance. Ripple current may be specified in mA or A; 1 A = 1000 mA. Sometimes you can get a better rating by going to a higher voltage part, but physical size may be a limitation.
>Endurance: Try to get 8000 hours or better.

I usually use Panasonic FR1 series capacitors, although United Chemi-Con EKZN capacitors are also worth a look. 25351068-tkog3zu3xmxabptjkcidpctj-1-0.jpeg

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.

Printer is not responding


This is the error light page from the S520. Not sure about this, but probably the same on the S530. 8 Blinks means replace the ink absorber and reset the counter. I think the ink absorber can be gotten at from the bottom, BUT NOT SURE. Try this at your own risk!

No Picture or sound, red standby light blinks six times


Sorry for how long it is but you should be able to find what is wrong in this guide

If you have any questions please dont hesitate to ask

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 0 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.

Lost oem power cord


You need to be sure the actual current supported by the generic universal adapter as some cant fit the requirements of your device so the nintendo will lack of current no matter the voltage you have.

Other thing you must take in consideration is the polarization of the plug as you can put inverse polarization and damage your console. Not like your case as you have a blinking light so looks more like and system error.

Try finding an original data for the current requirements in mA (i.e. 500mA) or the power also works before you make some calculations (i.e. 10w).
