Question about Bush 2871NTX 28" TV

Open Question

Bush LCD32TV022HD LCD TV has lost power and gone blank.

Hi

Hope someone can help?

My Bush TV is just over a year old and has basically turned off whilst in the middle of watching it. I assumed the usual things....fuse.....trip switch...etc but when checked these were not the problem.

The first time it happened I changed the fuse and the TV came back on but when I tested the old fuse I found that it hadn't blown.

The second time it happened I did the say again but the TV has not come back on again. There is no red standby light on as if the TV has no power.

I don't have much technical knowledge so if anyone knows what the problem is and can describe what I need to do please keep it basic.

Thanks in advance for any help you can offer.

Dom

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.

Hi I have a argos brought bush led tv that is only a year old and very rarely used but now for some reason it will not turn on at all I've changed fuse etc but nothing I'd say the tv has only dine abo


When you say not turning on is it completely dead, or has it gone into stand by mode, needing the remote to fire it up. Might sound patronising but are you sure both fuses are good?? Might have been in a spare room and got damp on the circuit boards and blown a internal fuse.

The TV is in protection mode. An internal problem was detected and the set shutdown to prevent further damage. If the set is only 9 months old, it should still be under warranty. Call and request warranty service.

Hi. If you leave your tv in standby try switching it off properly at tv switch leave a few hrs then switch on. Have you got hifi speakers or anything that is magnetic near tv if yes move it away from set switch set off wait a few hrs then switch on. Or if the above has not sorted problem the set has a fault with the degause circuit. Its not to bad to repair but you will need to use soldering iron.
