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

TV won't come on, it just stays in standby mode The red led just blinks when you try to turn it on and hear a little whistling noise if you listen closely. I was thinking it could be a power supply issue...


Hi.

The TV staying in standby and the light flashing indicates that the TV is in fault mode (often called protect mode). This happens when an internal fault is detected, and the main board set the unit in forced stand-by with the led color changing.

Before doing anything else try disconnecting TV from power for ten minutes. Restart the TV with no device connected, leave it on for a while and see how it goes. Test the TV with different devices (eg. DVD, VHS,sat box, console etc .)

In your case it looks like there is no clear indication toward a particular fault. The TV coming on at random times, may point at a defective PSU, but other failures such as defective main board, overheating, defective inverter, or faulty Timing controller (TCon) may result in the same problem.

The most common fault that may cause the symptom you described is PSU. Unless there is clear sign that the PSU is damaged, this is still far from being enough to decide that PSU is the culprit. The power supply must be tested before replacing parts. Testing is done reading PSU out on different voltages. This is an operation that must be done by a trained repairer.

The high pitched noise may be given by a defective PSU capacitor. In that case the bulged or leaking capacitor is usually easy to spot looking directly at the PSU.

To book a repair call the manufacturer at the number listed on the owners manual.

I have lost BBC 2 and all free view since Didital switchover


Well, I would say that this is how the cables company encourage you (the elegant way) to purchase their services. I know that there is a plan, in several countries, to stop all free broadcasts of various channels for people who do not have cables, especially if they don't have digital cables. There are devices which will allow you to receive the digital broadcasts to your TV. You can purchase one of these devices through any electronics store
