Tv repair worth it?

[cazowl]

Just a thought-if I turn my tv off with the remote (which leaves it in standby mode), but then later decide to turn the tv off completeley by using the on/off switch the following happens. When I next want to watch tv, I turn it on at the on/off switch and all it does is flashes like yours. This is because it has been left in standby mode prior to being turned off. Could that be the problem with yours?

 

Have yo tried using the remote to turn the tv on after turning the tv on with the on/off switch??

 

Yes, have tried turning it on/off by the remote and also the switch on the side of the tv loads of times, also unplugged it and left it a while and then tried again. Just keeps flashing at me - the cheeky bugger

Well I for one will not be poking around with it when I don't know what I'm doing! But interesting views, thanks. Upshot is, avoid Bush in the future. Got it

 

Do a total reset on that TV before you make any decisions. Almost everything now is controlled by software as well hardware and that can end up getting stuck needing to be reset.

 

Edit: read somewhere some bush also have problems with power regulator. At least in old days when electronics used relays for almost everything it was easy to sort the problem.

You're really selling it there:

 

"It's a cheap and easy fix, as long as you don't blow your arm off with a huge electric shock"

I'm well used to 'dangerous' CRT anodes with 20kvolt residuals and, if the OP's TV is not a CRT, there's very little chance of any "huge electric shock", unless one is dumb enough to leave the TV plugged in the mains during the repair (which, of course, I'm sure noone is).

 

cassity is right as a matter of general principle: most consumer electronics with a capacitor-related failure simply require a basic aptitude with a screwdriver (take off covers, put it back on), a soldering iron and pump (take off old capacitor, put in new one), and buying the right replacement at Maplins, eBay or somesuch.

 

The trick is in isolating the fault in the first place and, as many have posted on here, these days there's frequently a forum post, a Youtube vid or a similar online resource to be found if you search right. Alternatively, or in addition, get a cheap tester and learn to use it - it's a useful skill.

 

I've fixed all sorts of AV items that way, that would otherwise have ended up in a skip - but for the sake of a £0.50 component, a bit of time and not that much skill at all.

How do you do a total reset? Is that easy enough to do for the simple minded?

Very very true, too much waste is dumped that only needed a simple repair.

For that you need to check the manual, if you don't have one there will be manuals online. I don't know the model number of your TV. Put the model number down and I have a little online search for you what other people done with same problem.

You say no one is dumb enough to do it with it turned on but I'll put money on the fact there is plenty of people dumb enough to do just that.

 

Also the main dc filter cap will hold charge for a wee while and may not kill a fit adult but is going to hurt.

 

Telling people on a forum who you don't know to take apart a TV and fix it is stupid. You don't know the skill set of the person, you don't know if they are electrically safe they probably don't even know what a capacitor does!

 

My advice would be to spend time learning first before jumping into things, as in for an hobby or to make ends meet not to fix your TV that you know doubt want fixing asap

The expression you missed completely is "as a matter of general principle": I did not tell people to "take apart a TV and fix it", I suggested that people with malfunctioning electronics inform themselves about how to repair it, because it's not that complicated a task.

 

Basically, the same advice and meaning as your last sentence

Won`t the tv set need to be on to do the reset (which at the moment you cannot do). On my tv, the "reset to factory settings" is done via the remote with the tv turned on.

There are people that dump expensive large electronic items because the fuse has blown.

Done another search on bush 40" tv flashing light problem and keep getting many answers saying these have a known problem with the power supply and there are several people who have managed to fix it. The parts are not expensive but some knowledge and experience would be important to understand and fix these matters, If you don't have a solder iron and volt/ohm meter cap tester you better leave it to someone who does.

Ebay bush power supply board about £20 to £30

[cazowl]

yes thank you, I don't have any knowledge or experience, so may either get it repaired by someone if it is not too expensive or simply buy a new one (but NOT bush).
