Notice for problem for initial batch of TViX M-6500A
Dear TViX M-6500A customers,
Unfortunately, only after shipping the products we found several hardware related problems in M-6500A due to design error and/or low level of factory quality control.
You can use it as it is depends on the ambient temperature and usage of your M-6500A.
But, we understand that there can be many users who are not happy with current M-6500A.
So, we inform you the following information.
Some products may have all the problems below or a few of the problems.
1. Problem : Heat related (#1)
When HDD is not present inside the box, the unit will have incorrect air flow and the set will be overheated and picture will not be displayed.
Solution : Dummy HDD should be inserted and we are preparing it.
2. Problem : Heat related (#2)
Even when HDD is inserted, we observe a few M-6500A units becoming unstable due to heat.
Our recommended maximum operating temperature is 35 degrees C similar to other Blue-Ray players. It seems that there is a chance of few units becoming unstable even at 35 degrees C, even though all the sets we tested here works fine up to 40 degrees C. But we do not think 5 degrees is a good margin.
Solution 1. : Increase the FAN speed.
Solution 2 : Put a heat sink on the CPU(SMP8635).
We will use both the methods, because using solution 1 will make TViX too noisy and using solution 2 can only help cool the CPU not other parts of the unit.
*** To avoid the heat problem, we recommend the usage of M-6500A to be in a cool environment.
If you place M-6500A inside the cabinets, the internal temperature will rise and in turn the placed M-6500A may suffer from the heat problems.
If you place M-6500A on the top of hot devices like amplifiers, it becomes hot and may face problems.
In open environment conditions having room temperature of below 25 degree C, the M-6500A will work fine with least noise.
3. Problem : Clock related
TViX clock will be reset after a few hours of power off.
It was designed to last for at least a week or 2-4 weeks on an average, in the power off state.
Clock is not very useful because TViX does not shows clock when it's off. But it's essential when you use scheduled recording with the DTV Tuner(optional).
So, for those who has no plan to purchase the Tuner, it may not need to replace the set.
For those who is using DTV with schedule recording, the set must be repaired.
Solution : replace the wrong component with the correct one.
4. Problem : Not powering ON of the TViX with remote transceiver
Occasionally, M-6500A do not turn ON with remote transceiver.
Solution : some rework.
5. Problem : High return rate of working with USB target. (always USB ON)
Solution : some hardware rework
To fix all the above issues, the user needs to send his unit to a temporary AS center in Europe(and US).
The temporary AS center’s location is not determined yet and we are talking to a few of our distributors for help.
We are really sorry, but we cannot just issue a document to all the distributors for fixing on your own. This is mainly because the fixing points is are many and it needs special equipments to do it.
Due to this, we are planning to send our engineers to temporary AS center when it is decided, to supervise and help the repair processes.
[update] For those who do not reside in Europe or US, please return the set to the distributor in your country(we will notice them to you later). But please wait until our distributor has stock of replacement unit.(about 4 weeks)
All the users who want their set repaired or replaced will need to register on our web site first.
And this registration page(it's under construction, it's not normal user registration page) will be notified later.
[update] There is no V2 of M-6500A. One distributor mentioned this factory repaired set as V2 and it's misunderstood by some. There is no fully modified set in the market yet and we will be able to ship new(modified) unit after 10-20 days. Since, it takes time to for the goods to reach each country ,the availability will vary depends on where you live.
We understand that this is 100% our fault and DViCO will bear two way shipping charges and costs for repair.
Before we ask the customers to send their units, all the related parts should be sent to the temporary AS centre in Europe(US) and this AS process can only begin after 4 weeks.
[update] The detailed plan will be announced later, and some plan can be changed according to the parts delivery and other situation change.
We are really sorry for this and apologize for all the trouble and inconveniences. |
