Question about Televison & Video
Neither green or red. When tv is first turned on via the power button (one on the lower right side that pushes in to turn on) the led is red. Then when you push the top power button to turn on the tv the red led goes to green, after a few seconds it blinks 10 times and the light goes out completey. This did not happen until after a security camera was hooked up to it via the av cables. The video channel will come on but is this tv safe to use this way? I got it free, so there is no loss but it seems like a good tv, at least it was until I hooked my surveillance camera to it. Please advise. Thank you.
The blinks are fault indication. If the standby light blinks 10 times and the set shuts down after that;
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

5 times flashing light shows following possible problems in your tv..
• G2 is improperly adjusted.
• CRT problem.
• Video OUT IC1800 is faulty.(C5 board)
• IC301 is faulty. (A board)
Most probably cause is G2 voltage adjustment. If you know how to do it, please go ahead or look a tv tech around.

Seven Blinks: High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into shutdown. Check power supply and horizontal circuits.

there are two possible defects in your circuit.
However, if the led blinks for about 10 times your tuner is defective 90%.
You will need a scope to check or you will need to take it in for service.
