SOURCE: I have a Grundig Lenaro

Hi.

If the flicker is given by backlight, then the problem is either inverter board or power adapter. In some case a defective PC board may also be responsible. A defective inverter is the part that gives this problem more commonly.

Parts for most models can be purchased online entering model number in one of the websites below:

ShopJimmy

PartStore

Here a summary description showing how to test inverter and PSU.

Parts must be tested before replacement. The job must be done by a trained technician.

Call Grundig to check warranty status or to get a quote on repair.

See: Welcome to Grundig

Regards.

Ginko.

SOURCE: my grundig lenaro has sound

Hi Mike,
Power on the unit in the dark room then shine with the flashlight directly in the screen, you will barely see the images. This is because your backlight is not functioning. The following reason is the caused.
1. Power supply - missing B+(supply voltage) coming from this board feeding the inverter board. This is caused by faulty transistor, dried/leaky electrolytic capacitor, open fusible resistor.
2. Inverter board - even the B+ is good from the power supply, if the fuse, driver transistor, driver transformer is faulty no output to the backlight resulting to black picture.
3. Busted backlight - even inverter board is good but if this is busted resulting to black picture also.
Diagnosing the fault is technical and if you don't have necessary tools and test instrument and can't fix it yourself, I would advice you to look for an experienced technician to isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

There is some loose contacts to the connection wires inside the TV. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electric shock. Instead, contact any experienced service technician, or the nearest service center.

Hi. I have had the same problem for the last 6 weeks on my Lenaro 32"
Have contacted the Grundig Support and they are balaming it on the Digital Receiver. They say that the receiver component is made by Beko and thay have carried out an Over The Air upgrade which has caused this problem. Grundig contract out their services as this is just a trading name.
Their support is not willing to do anything and say that it is down to Beko.

I am now trying to get hold of Beko. After that I am going to contact trading strandards and Watchdog.

I have grundig lenaro 32"tv


Sounds like you're only viewing analogue channels.
Go into Menu and find Inputs and select & choose DTV. This will restore reception of Freeview (Digital TV) channels.
