I get error code 3 from my sony wega kv-32fq86e TV


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

Tv sony stop after 20 min standby led flashes 3 times


HI,
By three blink it means the B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is because there is problem in the power supply circuit. Check for any dry soldering in the power supply side. If the tv is working properly for 20 minutes then its sure that there is some dry soldering joints in the power supply side. You have to resolder suspected soldering contacts using soldering ion and solder. The dry soldering joints will look like on in the picture.

Sony KV-20Fs100. Same problen as #4620488. TV


Hi,
4 blink of power led shows problem in vertical deflection section and most probably vertical output IC is defective, replace it to fix the issue.
Regarding .rar file type of service manual files, download winrar software trail version from internet, install it and use it to unzip .rar file to get pdf manual file.
You wont get +B volts because tv switch to protection mode and power supply shuts down. Service manual has blinking standby led error code details as well.
Thanks.

Power shuts off 1 second after tv is turned on


Good Day,

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times.
1 - 2 = no error detected
2 - 1 = X-ray protect (high voltage or beam current)
2 - 2 = Short protect (short protect monitors low voltage supplies)
2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection)
2 - 4 = Vertical protect (usually loss of vertical from the source)
1. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB (NOT SHOWN IN THE SCHEMATIC).

2. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT.

3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB.

I hope this was helpful, BIG IRISH.

Will not turn on


When it shuts off. Try doing what's called a self-diagnostic test.
As soon as the television shuts try these steps.

Pressing on the front panel's ?INPUT? and ?MENU? buttons at the same time, and holding for 5 seconds,
activates the Self Diagnostic Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem
has occured since the last Initalization.

Please do Note: The front panel buttons must be used, NOT those on the Remote Control.

? The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
? The flashing then pauses for approximately 1/2 second.
? The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
? The Error Code is repeated a total of 5 times.
Example: If the Error Code is ?24?, the LED will flash two times, pause, and then flash four
times.

The Error Code designations indicating a malfunction, or no malfunction, are listed below:
Self Diagnosic Code Description
1 - 2 = no error detected
2 - 1 = X-ray protect (high voltage or beam current)
2 - 2 = Short protect (short protect monitors low voltage supplies)
2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection)
2 - 4 = Vertical protect (usually loss of vertical from the source).
