How to remove the vertical band out of your Optoma HD25?
Question from customers
I have a big worry concerning the appearance on screen of my Optoma HD25. In fact, in recent days, there is a very annoying vertical band. This is what I wanted to avoid when I’ve purchased this projector, it was one of the reasons why I opted for this Optoma brand. What should I do to your opinion?
Thanking you in advance for your assistance.
Answer from justprojectorlamps.co.uk
This problem is often due to poor contact at the motherboard. If you remove the cover of your Optoma (not recommended unless you are qualified), you will find the motherboard. When you turn on your projector Optoma HD25, it could indeed give you bad lines on the image. It is always caused by poor contact. The poor contact occurs when the motherboard and the various connections inside your projector is not properly connected.
Sometimes it also happens if a chip on the motherboard was not well-knit and in this case, some parts of the motherboard will be raised. The best decision is always to contact a specialist. Best regards,
