Hi Everyone, I recently bought a Tv Box ‘Zidoo Z9s’ and own a Sharp Tv model: LC-32L400M. Nothing is display after I hook them up using Hdmi cable. But it works when I connect the box to my new Xiaomi Tv model: L32m5-5Aru. Could someone tell me what may the reason please? Is there any way to make my Sharp Tv able to display output from the box? Thank you

Set the tv box resolution to Auto or 720p resolution.

Hi Weeza77, thank you for your advice.
But the problem is there isn’t any display at all, so not able to set anything

I have a Sony KLV-40W400A, all of a sudden no power no led. Symptom is the same even after I changed cable to try (the cable is similar to those PC PSU or monitor type, without external power adapter box type.

Are there any cheap and good repair shop where I can bring the TV to go for an evaluation before deciding whether to proceed with the repair?

Thank you in advance!

Set the resolution when connected to the Xiaomi TV.

Do the setting when you have it connect to Xiaomi TV.

Your Sony TV is those with external power adapter? If yes, use a meter to check if the adapter still supply 19v (I think) DC output.

The TV doesn't have external power adapter, as I mentioned in the previous post.

Hello it's likely the powerboard that's faulty. Do pm me if you would like to have some estimates on the repair cost as my dad is in this industry. The cost is dependent on whether the powerboard is repairable or if a new one is needed

Yeah do pm me on the likely repair cost, and whether it is needed to bring the TV over for a more comprehensive evaluation.

Then you need a new power board.

my LG 55" TV just went partial blackout. Is it backlight issue and if so, is it repairable?

TIA!
