This is common in every single major brand. I have seen this same problem in Samsung, LG, Sony and Panasonic. It is a terrible system I remember I had and old CRT for 22 years and just ended up replacing it because almost everything nowadays requires flat screen technology in order to work properly. But this things are simply badly manufactured. It is not nostalgia gobbles it is simply the way things are nowadays prioritizing mass production instead durability.

Hello. Unfortunately, I have not found any information about the backlight in this TV either. In the event that I do not have LED strips for the TV, I replace the LEDs themselves. Admittedly, it takes more time and skill.

This is Ironic and Simply an Awesome Repair as I have had this same Tv for about 9 years with what used to be 8 white dots but now I have 17🙈 and now I know basically what needs to be done.👍 I was wondering (as others have mentioned) which glue is used to fix the Lenses back into place And see you have Divulged this information yet I must ask (as I’m in the UK) if the Glue is available on somewhere like Ebay. You have a new Subscriber because of this Upload and thank you Sir for the help and any info on the Glue used.🙏👍

добрый вечер Mister Romanov. Thanks for this video, which is very useful. I have the TX-55CX700E screen with light spots and shadows. 1- I fixed them using your video (open the TV, glue the lens of the LED, and close the TV). Unfortunately, I still have 1 light spot and some shadow areas. 2- I reopened the TV (yes :-) ) and tested all LED. One is brighter than the other is. It creates the light spot. How can I fix it? 3- The background with reflector panel is not very flat. That creates the shadow area. Have you any idea about how correcting this? Again, I thank you for your video :-)

Hello. Perhaps the lens was wrongly positioned and glued, that you can see a white stain now? Perhaps the optical lens is dusty, then you need to wash it. (I use * Clin * window cleaner, or a similar window cleaner may be used.) Later, dry the lens with compressed air.

@TechV.R Жыл бұрын

the white diffuser layer can be cut along the deformation, and glued with double-sided adhesive tape.)

@@TechV.R спасибо mister Romanov. “Perhaps the lens was wrongly positioned and glued”. You were right! I unglued and glued them back. Now it is far better. “the white diffuser layer can be cut along the deformation, and glued with double-sided adhesive tape.)” OK I will try this, but I am afraid :-) Thanks a lot for all your help!

I got DX900 model with vertical banding issue. Can I fix it with the same method shown on this video?

@TechV.R 8 ай бұрын

Unfortunately, banding is a feature of the LCD matrix product. The uneven application of a layer of liquid crystals between the glass layer creates banding. This is simply a complicated LCD matrix production. Every TV has this effect. Unfortunately, there's nothing you can do about it.

@TechV.R 8 ай бұрын

The DX 900 model has fans on the back that draw dust. You may need to disassemble the LCD panel and clean the diffuser layers. Additionally, I recommend cleaning the fans to avoid error 13 later.
