Hi
I have a philips 32pfl7623d the backlight comes on but there is no picture. The light at the bottom flashes but never the same amount of times it always different. The light sometimes atays on and the backlight will stay on then the light goes out and the backlight stays on.
The psu voltages all seem ok (I have not looked at ripple with scope).
Any ideas

Hi, got a couple for this fault on this model: check contacts of LVDS cable between SSB and t-con. Also, update software. Last is check transistor 7CG0 (SI4835BDY) on mainboard for dry joints.
Do you have audio?

Hi
I cannot hear any audio but will double check tomorrow. I tried to update software I put it on USB stick but nothing seemed to happen. Do I have to do something to force update.

Service manuals says:
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: e.g. 3104 337 04731 _FUS
_Q591E_ 1.25.5.0_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 the USB stick.
How to upgrade:
1. Copy “AUTORUN.UPG” to the root of the USB stick.
2. Insert USB stick in the set while the set is in ON MODE.
The set will restart and the upgrading will start
automatically. As soon as the programming is finished, a
message is shown to remove the USB stick and restart the
set.
Manual Software Upgrade
In case that the software upgrade application does not start
automatically, it can also be started 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 TV remote control or a
Philips DVD RC-6 remote control (it is also possible to use
a 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 the download application has been started manually,
the “autorun.upg” will maybe not be recognized.
What to do in this case:
1. Create a directory “UPGRADES” on the USB stick.
2. Rename the “autorun.upg” to something else, e.g. 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 the USB stick.
3. Copy the renamed “upg” file into this directory.
4. Insert USB stick into the TV.
5. The renamed “upg” file will be visible and selectable in th
upgrade application.
Back-up Software Upgrade Application
If the default software upgrade application does not start (cou
be due to a corrupted boot 2 sector) via the above described
method, try activating 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 “INFO”-button on a Philips remote control or
“CURSOR DOWN” button on a Philips DVD RC-6 remot
control (it is also possible to use a TV remote in “DVD”
mode). Keep the “INFO”-button (or “cursor down” button
pressed while reconnecting the TV to the Mains/AC Pow
3. The software upgrade application will start.
Stand-by Software Upgrade via USB
In this chassis it is possible to upgrade the Stand-by softwar
via a USB stick. The method is similar to upgrading the main
software via USB.
Use the following steps:
1. Create a directory “UPGRADES” on the USB stick.
2. Copy the Stand-by software (part of the one-zip file, e.g.
StandbySW_CFT55_35.0.0.0.upg) into this directory.
3. Insert the USB stick into the TV.
4. Start the download application manually (see section “
Manual Software Upgrade”.
5. Select the appropriate file and press the “red” button to
upgrade.
