Toshiba 50HX81 Power LED Flashing

T,erry,
Been reading yur posts. Last night, I changed all 10uF caps on hyperboard? Plugged TV in (it seemed to power on when I plugged it in?). I noticed the remote would not work? Menu did work. Picture and all inputs appeared fine? After trying to figure out why remote wasn't working and repeatably unplugging, I now have flashing LED when plugging it in?
I don't know if I now have three problems after replacing caps on HB.
1) Remote doesn't appear to work?
2) I get flashing LED when plugged in?

Can you send me step by step for the flashing LED problem?

Thanks,

Jeff

Toshiba 50HX81 projection 'tv- blinking red light


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.

Toshiba TV 50HX81


Check fuses on Power Supply board (F850, F851, F852) and all other fuses. Replace blown fuses (will need an ohm meter to check fuses). I would also replace the two convergence amps (STK392-110's on the signal board, the big black ICs on the two heat sinks). This worked for me.

Toshiba 50hd82 Hyperboard


By your question alone the best place to start would be a good repair shop. The hyper module needs to be removed from the main chassis. After removing the two outer covers locate Cx261, Cx230, Cx270, Cz52, Cx178, Cx221, C514, Cx250, Cx670, Cx241 and Cx541. These are all 16v/10uf caps SMT but most techs simply replace them with the sub mini radial caps.
