Question about Standard (CRT) Televisions
hey Mr Fowgs!
Im writing you from Denmark, I have a B&O TV and am experiencing what sounds like exactly what you described. The TV was without power for a couple of weeks and then when it was powered again, the red standby light lit up as normal, but when I press the "on" button on the remote, it just goes out for a second and then comes back on. That's it. It also does this when I push the "step" button on the TV itself.
My boyfriend and I theorized that it could be a battery that needed to be recharged and perhaps leaving it plugged in would solve the problem. I can hardly believe leaving the TV unpowered is a fatal error. Perhaps it is a strange coincidence, I don't know. But then I read your post.
Can you tell me if you solved this problem, and if so, how? Is/was (hopefully!) your problem exactly as I described? If it was different how was it different? I posted this in the free forum, but thought I would try to get in touch with you directly. If you wouldn't mind you can email me at firstname.lastname@example.org .
Thank you for your time

If the TV goes in standby, then it is in protection mode.
Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.
1Theinternal circuits are jammed because of electrostaticcharges accumulating on capacitors, or because of a wrong voltage readby the main chip on your monitor controller board. this started theprotection circuit.
2 The protection circuit detected a wrongvoltage or abroken contact, identified an internal fault and kicked in, starting the flashing light.
If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
If under warranty contact the manufacturer ringing the number on the user manual

On LCD Payparticular attention at inverter and power board, power board can beinspected looking for bulged or leaking capacitors, then tested with amultimeter. The inverter is more difficult to test , there is need toread voltages, should be done by a tech. Also the LCD controller board can cause same problem
On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.
On Rear Projection : check lamp, lamp ballast, power board, and convergence.
On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.
