Display powers of with power up of AVC


how many blinks does the red light give in a row? This would be an error code?

The problem for 7 blinks would be an Interface board. Apparently there is a glitch in the interface board that sends signals to the television. Basically the glitch shorts out the board and the t.v wont turn on and you will see the power light blink 7 times pause then 7 more. You can replace the board with a new one and update the software on the new interface board.


If is isn't 7, let me know and I will help you out with this

thanks

Toshiba Plasma TV 50HP95 while watching TV screen went black and power light started blinking. No response from remote or buttons on the side of the unit. TV is approx. 7 yrs old.


Blinking of the power button denotes an internal circuit fault. If you wish to get more about the blinking codes to Samsung TVs, check this link. http://electronicshelponline.blogspot.com/

Hi bschaub796,
10 times blinking of your unit indicated that the processor sense the missing 15v from the power supply. This problem is quite technical since I've already read your post that you have a reading of 15v in P25.
Now, we have to examined it deeply to determine where the fault came from between the two board.
If you have a 15v coming from the power supply but its go to 0v after a while which trigger the 10 blinks, you have to check the feedback circuitry of the power supply for faults. If you can't find any faulty parts on that section means that the feedback circuitry trigger to shutdown because it sense fault in the D board.
Remember that it has a good regulation output from the power supply, the issue here is the feedback circuitry that sense the fault. If you are going to ask my opinion I've suspected that the fault is in the D board.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

No Picture or sound


The lamp cover door was not secured tightly. Door does not "push" shut easily. Got a little rough with it and latched it shut, then the tv worked fine.

If your brand is not listed, use the following procedure to scan through all codes.

6. When the correct code is reached, the device (whether a TV, VCR, or other) will turn off.
7. Press the Address button to store the code in the remote control memory. If the code is valid for your remote, the mode light will blink 3 times.
8. Turn the device back ON by pressing the Power button.
9. Try some other functions to make sure you have the correct code. Occasionally the Power button may work when others do not.
10. If the other buttons work, follow the current settings procedure below to determine the current remote settings.
11. If the other buttons do not work, repeat the previous steps. The scan will resume from the last code stored.
12. The mode light will flash rapidly when the scan has returned to the starting point and all codes have been tested for that mode. The remote control may not control some device models.
