This is likely a cycling clutch. It cannot just keep going or everything would just freeze up. Modern systems run until they build enough pressure, then cycle off until that pressure depletes, then starts up again. This nets much lower energy cost.

Car systems do the same.

3 blinks is the error code for the convergence ICs. You need to replace both STK392-110 convergence ICs. You can get replacement ICs at the following link and they provide installation instructions with pictures.

If the front power light is blinking three times then your TV has a problem with the convergence. You can get the correct replacement parts and full step by step photo instructions from www.TvRepairKits.com

  • 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 A2 slightly.

Panasonic tc p50g15 tv will not turn on tried 1 minute unplug reset and 20 sec power button hold in. Did not work now no led lights


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

My Sony KDS-60A3000 randomly turns off, then the red "Power LED" blinks three times repeatedly (not "Lamp LED"). We turn it back on, the process repeats again between 20-60 minutes.


3 blinks of Standby/power LED of Sony sets denotes a SMPS board [G-board] failure. .

Sir, carrier model42QG24-C comeing to off after 5 mint and then on after some time it repeate this cycle again and again. The red led on pcb is blinking regulerly..


More than likely it is cycling on its low pressure control.. It is an automatic reset device but each time it cycles off, the TDR (time delay relay) keeps it from restarting for approximately 5 minutes.

A steady and rhythmic 'heartbeat' on the circuit board typically means 'normal' operation. If it flashes, stops, flashes, stops etc, it would be giving you a fault code telling you what is cycling it off. You have to count the flashes, slow or fast or a combination of slow and fast and look up the fault codes.

GOOD DAY;

THIS COULD BE YOUR PROBLEM:

1. Red status LED, self-diagnosis error 44, check for open F9A06 on the Power PCB part # 283P128050 on the Power PCB 2. Red lamp LED, self diagnosis error 34. Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if missing replace the Power PCB part # 930B921002 3. LED stops blinking after 70 seconds of plug in but will not power on. This model is equipped with a keyboard lock feature, this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds 4. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector LE pin 3 and 4 on the Control PCB, if low suspect problems with the switches/buttons on the Control PCB part # 935D776001 5. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector LE pin 3 and 4 check good. Suspect the E2P PCB part # 934C121001 6. (LED does not stop blinking after plug in) Disconnect the USB connector from the card reader to the front from the Chassis, if the LED stops blinking after 70 seconds replace the Card Reader part # 299P271010. 7. (LED does not stop blinking after plug in) Disconnecting the USB connector from the Card Reader did not help. Remove connector FC from the FMT PCB and plug the unit in, if the LED stops blinking after 70 seconds with FC removed suspect a problem on the FMT PCB (part # 930B924002), if the LED keeps blinking with connector FC removed suspect a problem on the DM PCB (part # 934C116002). 8. (LED does not stop blinking after plug in) On the DM PCB (part # 934C116002) check C81A2, C81A3, C81B3 and C81B4 (1000 UFD, 16V, 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C). See Service Tip VS-78A 9. (LED does not stop blinking after plug in) On the FMT PCB (part # 930B924002) check C8F19, C8F21, C8F22, and C8F27 (16V 1000 UFD 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C).
