Top 10 Sony FD Trinitron WEGA KV-32FS120 32" TV Questions & Answers

This model does not have a G board. I will post when I have this solved.

I have a Zenith universal remote that i want to program to a sony 27 inch Trinitron, what are the codes?

My Sony KV36HS500 Trinitron is doing the same thing. Last night the next street over was hit by lightning. The "7" blink pattern was happening, so like the manual stated, unplug it for 4 hours. Which I did. The t.v. is back up and running fine. It's a nice t.v., better than the plasma I paid over a grand for, that's already shot. It's a good t.v. and good that Sony put in the stand by protection to prevent the t.v. from dying an unnecessary young death. Patience, don't rush it, unplug the t.v. and leave it sit. Also, don't use a power strip, that was my mistake, and unplug your t.v. if storms are in the area, I was too lazy to and now I had to deal with this, in 8 years, only twice did this happen. I'd buy another one tomorrow if they still made them.

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, 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 - 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 vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505
  
• Five blinks - AKB circuit (automatic kine bias), 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. In addition, unit could be in IK blanking, try turning up screen slightly.
  
• Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis 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. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

• Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negitive).

• Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.
  

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, volume 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 problems named, are 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.
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 four times. This would tell you that you have no vertical sweep, which 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..
IMPORTANT: After you repair the unit, you MUST 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 ). Press 8 and Enter,

Hope this may help;

Hello,
There are 3 reasons for 4 blinls
1.unit went to stand by mode because of h-pulse
2.Vertical defflection pulse stopped
3. power line is shhorted or power supply is stoped.

Solution:
1. check 13vdc on A board of powersupply stage
2. Check IC561 on A-board.

Good Luck

Hello,For model KV-40XBR800,

Pls check following area.

Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high
turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.

And NOTE: 6 blinks also can be Low B+ protection.

Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314

to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks.

Good Luck

Usually, pressing the display button on the remote will cure this. You may also check in the set up menue for any display settings.
Hope this helps,

You can only reset the TV when you have the remote as it requires holding down the RESET button on the remote control, then pressing the POWER button on the TV front panel. The TV will turn itself off, then back on again. Then release the RESET button.
Regarding your problem with the TV not staying on for 3 seconds, you can try unplugging the unit for at least an hour to perform a hard reset of the microprocessor. If the unit still doesn't stay on, you need to check the power supply or the entire board for any blown or bad capacitor, shorted terminals due to accumulation of dirt, or broken solders. It may be a tedious task and requires an electronic prowess to do.
Kudos and thanks for using Fixya.

Hi,
There is IC600 MCZ3001DB mounted on main board in power supply section, replace it. This will solve your problem.
MCZ3001DB is available in Part Store.
If you are handy with electronics stuff repair and can solder parts in circuit board then should attempt to repair TV by yourself and if you feel uncomfortable with working in TV, ask local tech to fix it.
Thanks.

Try a reset:

1. Turn on the television.
2. On the TV remote control, press and hold either the RESET or UP ARROW button.
3. While holding the RESET or UP ARROW button, press and release the POWER button on the front of the TV. NOTE: The TV will turn off and then back on.
   
4. Release the RESET or UP ARROW button.

If that doesnt solve it, you will need a repair.
