Question about Televison & Video

Technika TV LCD26-207 died in service

Watching TV then 'plop' it died. No Standby LED.
Fuses OK (I am an EX broadcast TV Engineer at BBC / ITN)
PSU SEEMS OK as it produces 9 volts on some outputs (but no standby LED)
Unable to say if 9 volts should be 5v or 25 volts.
Unable to tell if there should be more than 1 output.
No evidence of heat, it smells like new. AC input and front end seems OK as PSU EM radiation can be detected from several feet away AND there is an output (of sorts) of 9 volts.

Technika is apparently made for TESCO and they claim the set is unrepairable and unsupportable (Good advert)
I suspect PSU but this is anonymous with no legends to identify OEM.
IF I had a circuit, I COULD fix it.

I do not suspect dried electrolytics as these typically prevent start up. Once running, the values can be wildly off.... At least that is my experience with SMPSU's.

It COULD be another part of the set but I'm drawn back to the standby LED (Which works if powered seperately).
I'm not aware that any fault elsewhere could cause the Standy LED to NOT light so we get back to the PSU.

Set is very clean and JUST over a year old.
Tesco don't want to know.
I even tried my local TV repair man (I gave up fixing stuff a while back) and even he says TV is a Crock without a circuit.
Any suggestions, which might be "Take it to the tip".

I made my living fixing VERY expensive kit used in TV Broadcasting... I don't like throwing stuff away for the sake of a few pounds of parts.

best wishes
Rick from Bures

    Came home from work my tv was dead no power at all. I am a sngle lady who saved to buy this tv and it is only just over the year old I have a technika LCD 32"HDready. I took the back off and the fuse was black so I replaced it in fact I replaced both fuses and bought a new power lead but my tv is still dead. I spoke to someone at Teco and they really don't want to get involved as it is 13 months old and just out of gaurentee, I can't afford to take it to a repair shop and feel kind of cheated.

    Funnily enough I have the same problem... the warranty/guaranty ran out 2 days before the damn thing stopped working. I was wondering whether I could replace the PSU but from reading different posts on the net it would seem this won't fix the problem...
    I will never buy electrical goods from Tesco again.

    Technika LCD TV/DVD/Freeview is dead. Only sign of life is flashing red standby light. It is father in laws and he bought in from Tesco in Aug 2007(£230). Now out of guarantee however I complained to Tesco HO Customer Service that a TV should not fail after 18months. They sent out an out of warranty repair assessment form which was sent back. He has just received a cheque for £95

I know the cause of the fault is R983 - it appears to be a pullup resistor that kickstars the PSU. If you look you will find its slightly burnt. I dont know the value of this resistor. But if you connect a 60w mains lamp in place of the resistor the standby light will light then can start the set by pressing one of the buttons on the side of the set. If anybody knows the value please let us know. The part will only be pennies. Keith

Not worked on this model but they are all similar.
You may have a fault on another board which is shutting down the power board. Usually dried up or blown capacitors

Using Ex Pat Shield, BBC progs no longer start and a notice, 'Task failed at step 0: config was empty.' (Or 'Task queue failed ditto' Everything worked fine just days ago.


I have exactly the same problem, same error message. I first noticed the problem yesterday (September 11). Error message appears when trying to watch live TV through iPlayer. BBC News Channel works OK from BBC News website. Live sports broadcasts work OK through BBC Sport website. I uninstalled and reinstalled Flash Player but it made no difference.

No picture or sound, standby led flashes 11 times when first turned on after AC plug has been removed and reinserted into the AC outlet. Every attempt to turn on after the initial attempt yields 6 flashes...


It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. The flashing LED is justa coincidence I would think.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.
