Xbox One busted at only sixty days out with a grinding noise from the DVD/BlueRay

Xbox One busted at only sixty days out with a grinding noise from the DVD/BlueRay.  Won’t play anything.

Remediation

  • Maybe you can (still) get a replacement unit from M$.
  • Percussive maintenance; as shown here

Concept

  • ZigBee LAN.
  • Android (& iOS), availability on tablets and phone.
  • Cloud access: optional (remote hacking of your home is optional).
  • Color & brightness control on every lamp, individually.

Suitable for

  • indirect & mood lighting.
  • 600 lumens max (equivalent to a 60W incandescent; i.e. not very bright).

Product Line

Reminder

  • These are suitable only for indirect & mood lighting.

Gotchas

  • Philips has some sort of embargo/exclusive retail deal with Apple; so their products are only available and/or are much cheaper when bought through Apple Store (contra Amazon or 3rd party resellers, who often turn around and just buy it at the Apple Store and ship it to you with the Apple Store receipt in the box that you receive).
  • There are some similar Philips lighting products that come with their own proprietary remote controls.  e.g. Friends of Hue, Bloom has effect with Philips 709986048 Living Colors Aura Table Lamp, White. The older products are not “Hue” products and do not interface to the ZigBee base station.
  • There are minor protocol incompatibilities among the sublines of product.
    • The Hue products can have 50 devices per ZigBee subnetwork.
    • The Friends of Hue use the same protocol, but one can only have 16 of those per ZigBee subnetwork.

Availability

Initial availability was in the Apple Store only (but it’s universal, has nice Android support and Apple has “free shipping” so hey why not!).  However, come 2014-01-01, the embargo seems to be off, and the products seem to be available from Amazon at 1x to 3x the price of the Apple Store.

Actualities

 

Samsung LN40C650 “failing” with black vertical stripes (SOLVED)

Correct Diagnosis

  • Faulty seating on HDMI1 affects video arriving from HDMI4.

See Configuration and Specification below.

Remediation

  • Reseat HDMI1 (independent input from TiVo).
  • See the signal from HDMI4 (the Xbox) clear up.

Observation

  • HDMI1, HDMI2, HDMI3 are all “horizontal”.
  • Connections into these sockets have a tendancy to “droop” and place pressure on the female side of the connector.
  • Unless the inbound connector and wire is supported, the force of gravity, over time, will cause these connections to become loose and failure prone.
  • HDMI4 is “vertical” and will have less of this effect.

Actualities

These are barely acceptable when they are black.  When they become white, the display is unwatchable.

Indications

  • The behavior commenced after The Focus Group rerouted some video inputs and then replace them “as they were before.” See History below.
  • The behavior occurs independent of any video input signal; with no input video signal.
  • It occurs even in “Self Diagnosis” mode where the TV exhibits its own internally-supplied image.
  • There has been no internal intervention (never opened up the back).
  • The device has been mounted on a wall and cannot be jostled or insulted. But see History below.

Did you reboot?

Well, first of all, the display devices don’t run Windows, they run Linux. Rebooting isn’t generally remediatory for anything. But of course, I did a hard powercycle and replugged the power cables.

Therefore

  • The behavior occurs without a video signal => it’s not an HDMI decode issue.
  • Tough to believe that internal cables became spontaneously unseated.

History

  • Recently, The Focus Group decided to experiment with daisy chaining the video signal as Comast->TiVo->XBox->Samsung to give XBox One the pride of place
  • That’s the product vision/promise/aspiration for the XBox One: “The One Box for the living room” (think: as with the Windows monopoly; one ring to rule them all).
  • Of course this failed.
    • XBox One can’t control the DVR features of the TiVo.
    • XBox One can barely redisplay the live TV;
      It can redisplay a signal only if it’s previously decoded with the CableCARD that’s in the TiVo.
    • XBox One can’t play recorded programs or direct the TiVo to run its applications.
  • Thus, the XBox One, again, stands alone feeding HDMI to the Master Display. It is the Master Display that rules them all; as that is what provides ultimate the value.

Teaser

What are the chances that during this plugging, unplugging, replugging of HDMI cables, that some aspect of the HDMI male/female seating in HDMI1 through HDMI3 became loose enough?

Complete

  • Run (ahem) daily 8+ hours with sporadic intermissions.
  • Purchased 2013-08-01 (TV is 3.5 years old)

Configuration

Specifications

Samsung Series 6, Model L40C650; User Manual; 60 pages (10MB, huge)


But what did “the net” say?  Anything helpful? [tl;dr => Not really]

Consensus Diagnosis

  • The LCD is failing => it is not fixable, throw out the unit.
  • The LCD builds of that era were low quality and/or had low lifespan anyway.
  • Samsung makes “cheap TVs” and this is the best that can be hoped for, or something like that.

Rebuttals

  • Rly? => TVs should last “a decade” or so; that’s a problem that the TV vendors are actively trying to deal with … that people buy cars more often than they buy a new TV.
  • ahem => Isn’t it the case that the “cheapie TV makers” just buy their parts from Samsung’s remainders, not the other way around?

Alternate Diagnosis

From random prattle on the forums; it’s fixable, but …

  • It’s some fuse, caused by a “voltage surge.”
  • It’s some (internal) “tab” connecting to the LCD.
  • It’s some (internal) ribbon cable that as come loose.
  • It’s a “T-Con” board (every poster spells & abbreviates this part name differently).
  • It’s a firmware issue.
  • It’s an HDMI decode issue => replug the cables, powercycle (these were perilously close to correct)

Trumark RRT Slingshot Powerbands

From Tuning Your Slingshot from slingshot-shooting.de (melchiormenzel.de)

Read it…

From How to install Trumark® Slingshot powerbands in slingshots.com

  1. Dip the band ends into approximately 1/8 inch of ordinary rubbing alcohol that does not contain glycerin or lotion. Do not use soap anywhere on the bands, as soap will cause the bands to deteriorate.
  2. Slip the bands about one inch onto the slingshot prong-ends. (Be sure that both bands are slipped on an equal distance).
  3. Immediately (before the alcohol can dry) turn the entire one inch of rubber that has been slipped onto the prongs until the leather pouch is adjusted properly and “sits” straight. Your slingshot will shoot straighter if this is done properly.
  4. Do not shoot or pull backwards on the slingshot powerbands for 24 hours to allow the alcohol to dry.

Question: But will it work with Linux?
Answer: No.  [2012-12-28] It does not; it does not “work on Linux.”   It might, but it does not “just work” on Fedora 17.  You get a green screen, but nothing else (nothing in randr, nothing in /var/log/messages.  There is folklore that if you turn off kernel modesetting then something good happens.   This device still does not “work on Linux.”   Without further hacking, tricking or development.
