SOURCE: re: standby mode???

No really the standby mode dosent mean the sets fried or unrepairable. It just means that the sets in a shutdown mode till a power supply problem is corrected. They have shut down protection when the power supply dosent regulate the b+ and if it didnt shut down it would give off tons of X type radiation. thats just a safty on the set. seek a pro to assist you in repairing the set. Good Luck

If you have Hitachi model number 50UX58B, 60UX58B, 50UX58K, 60UX58K, 50SBX78B or 60SBX78B and you have the following symptoms you may want to grab a repair kit from www.TvRepairKits.com. They have put together a kit that includes the parts and instructions to fix these models. This is a fairly common problem with the above model numbers. It is typically caused by a blown capacitor and pico fuse. Again, you can get a kit from the above address. 
Here are the symptoms...

Primary Symptom: No Audio or Video. Power light will come on briefly then shut off.
Other Possible Symptoms : The green LEDs on the circuit board light up for a few seconds then turn off.

Hope this helps,

Flashing stand by light and tv does not respond to any swithc or remote


Hi.

If after the fault the TV went in standby and does not wake up, staying there with led flashing, then the TV has on protect mode after detecting a fault.
When this happens higher voltages are shut down to prevent further damage. Only the +5V line will stay on to keep the TV in standby.

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.

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.

Power off is when you press the switch.
Shut down is when you turn off from remote and TV stays in standby with led on.

Red led stays on after turning off.


Aren't you talking about the standby led? cause that is perfectly normal... when it's on it means you can turn the TV on by remote, usualy it goes away when you turn the TV off manualy by pressing the OFF button on the set, but is this really your problem?
