I have a 3 year old, 65 inch toshiba, rear projection tv. The model number is 65NH84. Ther last couple of days, it has been making a loud popping noise. The screen gets blury and then the tv is normal. Now the tv cuts off after each episode. The red power lights blinks and the tv wont come on. I disconnected the cable box and hooked straight to the cable outlet. It still does it. Can u help me.
Thanks,
Wade

One thing that comes to mind when you say high pitched sound is the HOT ( Horizontal Output Transistor). You may be able to find one at fry's electronics. They are pretty cheap. If you are handy and know something about electronics you may be able to replace it. I am not a TV tech, I have a background in electronics and like to play with them from time to time. Not sure this will help but good luck

I have the same problem. I had someone come look at it and he showed me the problem but a terrible price, so i didnt have it fixed. The reason the light blinks is there is a problem and the safety mech is kicked in which shuts the TV off. If you take the back of the TV off, about 15 screws, you will see right in the front on the left side a part shaped like the letter "C". The number on top of mine is S5 19 2. That is the part that needs to be replaced. Now to find the part on the internet and figure out how to change it out. any suggestions?

The TV is on protect mode.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
Also
ensure that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem with no receiver box
or dvd connected.
If that does not work, and you keep having a flashing
led on front of the TV, and tv turning off by itself after a while,
that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.
1The
internal circuits are jammed because of electrostatic
charges accumulating on capacitors, or because of a wrong voltage read
by the main chip on your monitor controller board. this started the
protection circuit.
2 The protection circuit detected a wrong
voltage or abroken contact, identified an internal fault and kicked in
, startingthe flashing light.
If you are in situation one, then theTV 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.
Common faults
that can occur are a blown capacitor on power board, a
convergence IC has blown, or a fault on Digital board.
Check also
the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you
can get same flashing state because of the video cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.
I have the sames t.v you have to go in the back flip the power cord switch...then reboot the t.v.
