Hi forum --
I can use some help with troubleshooting a Samsung Plasma - I tried to search the forum for like issues but they all vary from one set to another --
Here is my TV issue; When the set is plugged in the red power light is illuminated ON. When I press the ON button the led flashes OFF and ON 3 times before it goes into a red double flash 5 times sequence. There are no other indicators as far as Picture or clicking. No Evidence of any bad Caps or Burn Markings - This TV is dead --
I took some photos of the TV with the cover removed and I took some voltage measurements to display to the forum for direction. Also there is no green flashing LED illuminated on the Main Controller Board.
Please let me know if there are additional information needed -- Thank You..
On the PS Board there are 2 connectors that I was able to take measurements during the events --
CN802 - Is ties to the right side of the PS Board
1. D15V - 15.4V then turns off and then ON again during the initial 3 O3/Off then 0V during the 5 double flashes.
2. GND - (0V)
3. VA 0V - No matter condition
4. GND (0V)
5. N.C.
6.VS 0.9V then to 0V - It was trying to come up during the 3 time seq but went to 0V during the 5 double sequence.
7. VS - Same as above
Next Connector - This connector is tied to the controller board - Right Below the PS Board. 18 Pin Connector --
1. PS ON 3.3V - Turns Off During the 3 On/Off and then to 0V
2. STBY - 5.25V Steady ON no matter condition
3. GND (0V)
4. D15V - Same as the above Pin 1
5. GND (0V)
6. GND (0V)
7. D5.3V 0V no matter what condition
8. D5.3V 0V Same as above
9. GND (0V)
10. D15V Same condition as above
11. D5.3V 0V
12. D15V Same as above Condition
13. D5.3V 0V
14. D5.3V 0V
15. V5 - ON 0V
16. GND (0V)
17. V5-ON 0V
18. GND (0V)
Thank You,
Richard
