Deltavision TV Repair

Important notice from Deltavision TV
In order to avoid catching (and spreading) Coronavirus (COVID 19) and to minimise any risk to my valued customers and my family, the following steps are being taken.

Deltavision TV is now open for business but with careful measures in place.

You can still contact me in the usual way, either by phone, SMS, Facebook messenger, or by using the contact page.

I will be happy to take in any repairs you may have, but every precaution will be taken regarding prevention of spread of the COVID 19 virus.

You are welcome to bring your faulty TVs VCRs DVDs etc but please phone first.

These items will then be carefully wiped down thoroughly with a suitable mild disinfectant on delivery to me, and again when you collect them.
The disinfectant has been tested on many surfaces and products with no adverse effects to their surfaces, but if you have concerns about this, please do not bring them.

Thank you for your co-operation in these awful times, but I am sure if we all act responsibly and follow central government guidelines, we will eventually see the end of this.

Please be assured, if I or any of my family show any of the symptoms of COVID 19 infection, we will self-isolate and business will close immediately.

To all my customers, please stay safe!

Repair methods we use

EEPROM (NVM) file corruption

I had a 32" LED TV in for service with the "stuck in standby" symptom. This can be caused by a whole range of things from problems in the power supply, to a faulty main board (SSB). In this case the TV's NVM (EEPROM) ic was corrupted.

This is the main memory ic that has all the data to tell the main board microprocessor how to perform, ie, how to start up, what modes and levels should be loaded.

Any information in here that isn't quite right can cause many different problems, and the TV would not work properly.

We sometimes can obtain the file to re-program the EEPROM, and in this case I managed to get one for a very similar main board/ TV, although not exact, so it may work, it may not! This time I was lucky, and my valuable time not wasted.

LCD/ LED TV T-Con (Timing controller) repair methods.

Problems on Tcon boards usually manifest themselves as various picture anomalies, ranging from no picture at all (completely black or white screen) to weird "rainbow" effects. Not always are these problems repairable, but many are.

The gallery below contains images of some of the faults encountered in our workshop.

I will add more pictures to this section as i encounter them.

This is how I replace the AS15-F TFT buffer IC found on many T-con boards. This chip can be responsible for many varied picture faults (please see previous section.
