http://youtu.be/gO8m2AuK5NA - A video I made to make this explanation plain and simple.
Model No: LN40B530P7F
Model Code: LN40B530P7FXZA
Issue: When turning on tv, start up audio plays, Red LED begins to flash for a total of 5 times and then goes out, the screen also comes on for approx 1 second then off for 5 seconds it does this about 4 times then the screen stays black. I then can push the power button and it makes the sound of the tv shutting off.
The menu only shows when rest of the picture can be seen.
TV history is unknown for it was given to me, but I believe it was ran pretty much 24/7 till began to have issues.
I have done some research and this seams to be a common issue with this model of tv how ever most everyone has had burnt transformers on the power board and this does not seam to be the case here as I have recorded my ohm readings at 02:01 and seams as if they are within acceptable range.
I do not have the correct equipment to completely test capacitors as well but have done the dmm test by going to ohms and charging the capacitor and reversing my leads and watching the numbers go negative then to positive and all capacitors reacted as I would expect.
If there are any other tests or ideas on what I should dig into I would be very thankful in the help I get.
Thank you.
