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

Push power button and it stays on for a couple seconds and then shuts back off. No picture comes on. Thank you Jeanette


To determine what your problem is:

UNPLUG TV ANDTHEN PLUG BACK IN---TURNON---GREEN POWER LIGHT COMES ON FOR A MOMENT ANDGOES OFF.

PRESS AND HOLD "device" and "menu"buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

Let me know

My Sony Wega TV does not turn on the first time i try.


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.

Hi,
Symptom shows Lamp is weak in result and causing restart of TV again and again. Your TV requires new lamp as per following part number...
A1085447A* LAMP BLOCK ASSY XL-2200U
It is available in Sony Accessories Store for $200 and replacement procedure is written in instruction manual of TV.

Always buy Sony original lamp for TV and avoid aftermarket / cheap lamp for TV safety.

TV shuts off and red standby/timer lights blinks red until I power the set off. When it shuts down it does so with a very loud snap. When I turn it back on the screen is blue and has light blue...


The most common cause for what you are seeing is a shorted gun in the picture tube. When 2 elements (heater and cathode) of one of the guns inside the neck of the picture tube touch, that gun goes full on and overloads the flyback (high voltage) transformer. If it is in the blue gun, the screen will go bright blue with light blue "retrace" lines in it. The computer senses the overload and shuts the set off. At 2 years old the tech most likely tried removing the short by arcing between the elements. This works sometimes but the short often comes back a few months later. Another attempt at removing the short could be tried, and it might work this time, but it may or may not work for long. The ony other solution is to replace the picture tube but that would cost much more than the set is worth. A qualified tech will be able to tell you if this is the problem in your set.

TV Shuts off, Screen Problems


The problem could be the power supply, the flyback trasformer or simply a bad connection. A repair cost for this TV set could run any where from 75 bucks all the way up to 225 or so, depending on the problem. Good Luck
