problema con actualizacion 0.14.104 para 46pfl8606h

Hola, soy nuevo en el foro. Tengo un problema con la tv. Acabo de actualizarla con la ultima version de la pagina de philips, la version 0.14.104. Antes tenía la 0.14.99. Con esta ultima la imagen era perfecta incluso con los canales tdt generalistas. Tras actualizar, la imagen es pesima. Ha empeorado muchisimo. HE intentado cambiar parametros pero nada. No sé si se puede volver a la anterior versión que tenia. Si esto es posible, os ruego me digais de donde descargarla, ya que me he puesto en contacto con philips y me han dicho que lo sienten, pero no se puede volver a una anterior ni han querido remitirme esa version. No se que hacer. Supongo que solo esperar a una nueva actualizacion.
Ojalá me podais ayudar. Gracias

Philips does NOT advise to downgrade, that is why Philips does not provide older SW versions.
Better wait for a NEW SW version, which is published on regular basis!

If you insist however, it is only save to downgrade from e.g. 140.27 to 140.25 or 140.23 (same SW branch).
Do NOT downgrade from e.g. version 140.xx to 75.xx. This can result in a undefined TV behaviour requiring a Service intervention! So, be aware that downgrading the TV is at your own risk!

Instructions for downgrade to a lower SW version:

* Switch the TV "off": unplug mainscord or use TV's mains switch.
* Unzip file and copy "autorun.upg" in the root of an USB stick, and plug it into TV.
* Press the OK (or ARROW DOWN) button on the remote, keep it pressed, and cold-start the TV (with USB stick plugged in).
* You will now enter the software upgrade/downgrade menu.
* Choose the correct autorun.upg and start the software update/downgrade.

Automatic Software Upgrade
In "normal" conditions, so when there is no major problem with
the TV, the main software and the default software upgrade
application can be upgraded with the "AUTORUN.UPG" (FUS
part of the one-zip file: eg 3104 337 03801 _FUS _Q581E_
0.37.0.0_commercial.zip). This can also be done by the
consumers themselves, but they will have to get their software
from the commercial Philips website or via the Software Update
Assistant in the user menu (see DFU). The "autorun.upg" file
must be placed in the root of your USB stick.
How to upgrade:
1. Copy "AUTORUN.UPG" to the root of your USB stick.
2. Insert USB stick in the side I/O while the set is in ON
MODE. The set will restart and the upgrading will start
automatically. As soon as the programming is finished, you
will get the message that you can remove your USB stick
and restart the set.

Manual Software Upgrade
In case that the software upgrade application does not start
automatically, you can also start it manually.
How to start the software upgrade application manually:
1. Disconnect the TV from the Mains/AC Power.
2. Press the "OK" button on a Philips DVD RC-6 remote
control (it is also possible to use the TV remote in "DVD"
mode). Keep the "OK” button pressed while reconnecting
the TV to the Mains/AC Power.
3. The software upgrade application will start.

Attention!
In case that you have started the download application
manually, the "autorun.upg" will maybe not be recognized.
What to do in this case:
1. Create a directory "UPGRADES" on your USB stick.
2. Rename the "autorun.upg" to something else, eg to
"software.upg". Do not use long or complicated names,
keep it simple. Make sure that "AUTORUN.UPG" is no
longer present in the root of your USB stick.
3. Copy the renamed "upg" file into this directory.
4. Insert USB stick in the side I/O.
5. The renamed "upg" file will be visible and selectable in the
upgrade application.

Back-up Software Upgrade Application
If the default software upgrade application does not start (could
be due to a corrupted boot 2 sector) via the above described
method, you can try to activate the “back-up software upgrade
application”.
How to start the “back-up software upgrade application”
manually:
1. Disconnect the TV from the Mains/AC Power.
2. Press the “CURSOR DOWN” button on a Philips DVD RC-
6 remote control (it is also possible to use the TV remote in
"DVD" mode). Keep the "cursor down" button pressed
while reconnecting the TV to the Mains/AC Power.

1. disconnect power cable
2. insert USB
3. press keys {DVD} then {OK} on Remote Control
4. press and hold key {Down} on RC and plugin power cable

This boots the TV on the firmware upgrade page but I've found that it only recognises a firmware on the USB stick that's older than the one that you've installed most recently. It's good enough to get the TV working then you can run any upgrade version you want.

Si se pulsa con el mando: "123654"
aparecen datos con información del TV (versiones FW, etc ...)
(es de interés para saber qué tipo de versión de FW usa el TV -- Q5551, Q5553 .. etc)
