55H7B 1. Tv Off - red light indicator. 2. Tv On - "Hisense" blue flash after 3 secs, then screen goes black and no sound. 3. After "Hisense" blue flash red light blinks 6 times then appears off.
Cheaper to replace than fix, trust me on this.
Testimonial: "Please explain, why?"
Years of experience.
Thanks, but I'll try the ShopJimmy.com tutorial because it explains my situation and possible repair other than someone with years of experience.
Well suit yourself, let me know whether I was right. Have a good evening and god bless.

Check your users manual. Normally if it is blinking it is powering up, but may be different depending on model.
SOURCE: Red LED blinking after turn on the TV (Philips Plasma 42PF9631D
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.
