had the same problem with an s80 this week- no warning lights nothing. was the regulator. when you have it fixed cancel all the trouble codes as when voltage is low everything registrs low signal input and makes the car go into get me home mode.

You either have a Faulty Horizontal Oscillator IC? OR something, on that 1.3 V Output, is dragging that output down and on that output, something drawing too much current, and causing the IC, to not be able to drive to it's full potential, usually 5 V DC in a logic circuit, but if CMOS, then even 12 V DC.
All one can really do, is find the "Cause" of the low output, remove the "Fault" and/or change the IC, too (It's most likely damaged anyway? So I usually do)

You need to get the parameters of the IC & Semi's that you are working with and check the output against what it should be.
Also, you did not indicate if you were using a service manual. If not, then I implore you to obtain one, as without it, one really cannot work effectively.
As I always used to say to my students: Are Your Voltage Correct? Specifically, starting with the PSU, as if this isn't 100%, nothing else can be. Anyway check all voltages around your IC's & Semi's. Also remember the technique of "Cut & Test" too, isolating parts of the suspected circuits, by cutting a trace, or chopping a Leg or Pin, on a Semi or IC, can be useful in tracing where the fault is going. One other thing is Current Measurement, cutting into a circuit, and inserting the Ma meter, into the circuit, will also soon show you where the problem is, reduced current usually indicates a "Short", a high current usually show a disconnection, or "Open" circuit.
Hope this helps.

No Standby voltage and no led


The standby voltage comes from the main power regulator board itself. If there is no standby voltage, there is no need to go further. Replace the main power supply board [SMPS] as card basis. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

I have a Kohler 12 RES home standby generator. Once in a while when the power goes out the generator will start and then immediately shut down with no fault codes. When I flip the control in the unit


Check the inlet fuel pressure, on exervise there is no load, when power is out it is loaded and demands more fuel. Also check for bugs blocking gas regulators vents etc

RED FLASH AND TV URNS OFF


  • 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 IC406audio 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.

Model # wd-62725 reset light will not reset, keeps blinking rapidly.


This is an indication that you have a problem on the power supply section or on the load because of the following reasons :


1. Over Voltage - the regulator might be cycling on over voltage due to lack of load.


2. Over Current Protection - excessive load or faulty power supply cycling will

trigger the over current protection circuit.


3. Leaky Capacitor - a dried up main filter capacitor or other filter capacitor in the power supply that is producing an out-of-regulation condition. A bad filter capacitor on the output of a series regulator may result in excessive/drop of voltage once sense by the processor it will not power up the unit unless isolated.


4. A problem with the microcontroller, relay or its driver, or standby power supply.


This is not DIY and quite technical so I've advice you to look for a qualified technician or send it to repair shop to isolate the problem.


But first check if your unit is under warranty then avail it because the manufacturer of your unit will fix it for free or with a little charge only.


Thanks for using fixya.

Standby light blinks 7 times and tv will not turn on


Hi,


Thanks for using FixYa. Standby light blinking 7 times means high voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. You’ll need to check power supply regulation and horizontal circuits. Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Sony 50 Wega LCD flashing red light


Hi

How many times is the red light flashing? The number of times the red led blinks means---


  • 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.

My 61 In sony xbr flashes the standby light 5 times


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 a 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 nine blinks, (depending on the fault), about a third of a second apart, then a pause for 3 seconds, then the two to nine 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, 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.

  • 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 GA_googleFillSlot("TL-IMU-Article");blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402.
