Sanyo DP42849 no picture but has sound


Sounds like an inverter problem. On some of these sets, the inverter and the power supply are on the same board. These boards tend to be quite pricey, $100 + range. I've worked on your particular model with the same problem, and it was a bad inverter/power supply board. I would recommend you get a diagnosis to be sure.

I have a Aquos LC-37GP1U new out of box. Have the blinking light issue. Power on for 2 seconds and then shut off. Replaced the power supply board as it was cracked. Still didn't help. Should I be...


Hi,


You have to check if the replacement power supply board is the same part no. as the original one, it is printed on the board itself.


I don't think that the fault came from defective electrolytic capacitor because like what you have said, the unit is new out of the box and you've already replaced the power supply board which is most of faulty electrolytic capacitor came from that board.


You've mentioned also that the original power supply board has cracked, I've suspected that the main board also has been damaged because the blinking led light error codes will be encountered if the power supply board or main board gone to malfunction. If you've confirm that the power supply board is the same part no. like the original one, then I would advice you to replaced the main board.


Please let me know if you need further assistance.


Have a great day!

I have a phillips plasma tv model # 50pfp5332d/37. It has sound but no picture. I changed the 4 capacitors that appeared bad and still no pic. There is one blinking led in the middle circuit board...


You've still got bad Capacitor(s) somewhere out of the 50 or so that are in their. If you're replacing Capacitors then if space allows its always better to try and increase the voltage rating a level 16V to 25V etc to help try and prevent them blowing again.

Phillips model#42PF7320A/37 no picture ,no sound red light blinks 7 times


Hi tileman5,
Your 7 blinks (error code) means that your 8.6 vdc in the power supply section is faulty.This was sense by the standy-by power supply's initial test. This voltage is easy to locate in the power supply board, each output voltage is written in the board itself. Concentrate in its regulator circuitry. Look for open fusible resistor, shorted transistor and leaky/dried capacitor. The unit is disable unless you fix this 8.6vdc fault.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

No power to my Phillips 42 inch Plasma 42pf7321d/37, just a red blinking light


Most likely it going to be a power supply related problem. The red blinking light is a code for a TV tech to diagnose the problem on the power supply board itself or the board that regulates the power for the screen. Some manufactures call it a Backlight Inverter Board. A TV repair shop should be able to look at it for you and tell you which board is bad.

Philips 42PF5321D/37 Error Codes


replacing ssb for 4 blink error was correct as error is communication failure specific to micro processor on ssb. getting an alternate error after replacing ssb would suggest either wrong ssb or defective ssb. verify vendor number on ssb tuner on original and new ssb and if same reorder that board and if not order per original board
