I wrote to Kef support about an identical issue. Their replay is below.
By the description you have given, it sounds like the power amplifier
board in the subwoofer has failed.

Unfortunately your subwoofer is no longer covered under warranty as the
electronics inside comes with a one year warranty as with all KEF
electronics, and the warranty card would have been supplied inside the
box.

However, you can return the amplifier section to us by removing the
screws on the very outer edge of the back of the unit and disconnecting
the cables inside. Once removed, carefully package the amplifier and
then contact the Service department on 01622 672261 with the serial
number to hand, they will then give you a returns number. Once you have
a returns number, you can send it to the following address with a
covering letter. When sending the parcel, please make sure that you send
it recorded delivery or get a tracking number if sending by courier.

PLEASE NOTE THAT ITEMS NOT BOOKED IN WITH THE SERVICE DEPARTMENT BEFORE
DESPATCH, MAY INCUR FURTHER DELAY.

The address is as follows:

THe problem is in the set top box. Or common called the tuner box. IT looses the 5 volts to the main display and thus the monitor will go into a shut down state. THESE boxes are factory repair only and must be sent off to repair.

No panel lights, no fan, flashing front left light


the blinking lights means power issue. If you already plugged the computers power cable directly to the wall and stll get the blinking power light then your probably looking at a bad power supply in the computer.
Just for measures go into the system and if you have a video card remove it and start the system up. Also take out the memory stick and put them back in just incase during the move some components got loose. Put on your detective hat and check all connects. if problem still persist replace the power supply. In Computers terms thats called the PSU (power supply unit)

TV won't work. Green light blinks continuously on front panel


Your particular bigscreen has a digital module located on the left rear of the unit, and is mounted vertically. This module can be removed and the shielding taken off. On the component side of the DM module is a small power supply circuit board which needs to have all five electrolytic filters replaced. The filters are typically 1000 micro farad at 25 volts and are easily obtained by you local electronics supplier or repair shop.

The reason your unit does not stop blinking is due to these out of tolerance electrolytic filters. They became out of tolerance when the unit was left unplugged during the move. Once the filters are replaced, and the module re-installed, the green blinking light will extinguish after about one minute, at which point the unit will turn on.

Red light flashing, no picture/sound!!!!


HI, this unit has 3 main fuse links on the main board that may be blown. the fuse links should be check before you move further into the diagnosis stage. once you have checked the fuses and they are still in a working state, this will confirm a power supply board failure. this board provides and regulates the current flow and distribution of it throughout the entire unit. If the fuses are fine and the power supply board is damaged, the green light will come on briefly then, the main control will notice that the power supply is not functioning properly. Once the main control board senses an abnormal current, it will shut down the TV rendering the red light warning. The list of fuses to check are below. Remember, if they are fine and working, the issue will be the power supply board itself and, it will need to be replaced.

Hp 1350 all-in-one


When power is applied to the all-in-one for the first time, the power light is solid and the check paper, check print cartridge, black copy, and color copy lights flash, the display will be blank, and the all-in-one will not respond. One or more of the following symptoms will also be observed: The all-in-one keeps turning off Cannot print, scan, or copy The print carriage will not move Windows plug and play (device detection) does not occur The all-in-one does not respond when buttons are pressed, including the power button. SOLUTION: This problem occurs for two reasons: the front panel cover was not installed or the ink cartridge access door was not closed before plugging in the all-in-one. The front panel overlay must be correctly installed before the power cord is plugged in. Follow the steps below to correct the problem: Disconnect the power cord. Lift the scanner lid and carefully line up and install the front panel overlay. Plug the power cord in. The print cartridge access door must be closed before the all-in-one is plugged in for the first time. The all-in-one cannot complete its first initialization until the door is closed. Follow the steps below to correct the problem: Disconnect the power cord. Locate and close the print cartridge access door. CAUSE: The all-in-one initializes when it is plugged in for the first time. While initializing, the all-in-one scans a bar code on the under side of the front panel cover requiring that the front panel cover be in place and that the scanner be operable. The scanner cannot operate when the cartridge access door is open On light (green) - On Check Paper light (amber) - Blink Simultaneously Check Print Cartridge light (amber) - Blink Simultaneously Black copy area backlight (green)- Blink Simultaneously Color copy area backlight (green) - Blink Simultaneously Issue Front panel overlay is not attached at all or not attached properly Solution Turn Off the all-in-one. Attach front panel overlay as instructed on Setup Poster. Turn On the all-in-one.
