Question about Televison & Video

Open Question

Wharfedale DMP82 mini hi-fi unit. It's stuck in standby. When the standby switch is pressed, the display lights up then goes back to standby. LCD display is on as the 5v line is still present. The 2 x 14v lines are at 4v and rise momentarily as does the 12v line. The standby line is 0v then rises to 2.5v when the switch is pressed. Not an easy unit to take apart and I've only managed to get the back (PSU) off. Any ideas?

SOURCE: Power on problem for My Syntax Olevia LCD TV 23"

I have a 24" Olevia LCD TV. Same symptoms (Stdby LED is on, press power and it flashes off, then back on). The USB cable to the Service Port also worked. But being of sound technical mind, I figured this means that the PC is supplying the +5v to the circuit. What I did was disassebled the TV, carefully disconnected all the cables, and opened it up to reveal the circuitry. I looked over the circuit and noticed the 1000uf/16v capacitor at position CS21 was failed and bulging. I removed the cap, tested it and verified that it was indeed failed. I went to a local Radio Shack and picked up a 1000uf/35v electrolytic, after all, the value is what mainly matters as long as it's not lower voltage than the original. I replaced the new CS21 capacitor back in the circuit (it is polarity sensitive, so pay attention to what the original mounting position is). I reassembled the TV and Viola! Works! No need for the USB cable to the Service Port!

I hope this helps someone!

Sky box green light on permanent


Sounds as if the software is corrupt. Try a forced software update...

1) Switch the digibox off at the mains power, so no lights are displayed on the unit
2) Press and hold the BACK UP button on the digibox (not the remote control)
3) Whilst holding, switch the digibox back on at the mains power so the red standby light is displayed
4) Wait approximate. 10-20 seconds for the remaining 3 lights to display, at which point you can release the BACK UP button
5) Allow the digibox to download the latest software, which can take 10 minutes before returning to standby
6) Leave 60 seconds then power up as usual

A software update/refresh will leave your recordings intact. You won't lose anything.

If this doesn't solve your problem, then the next step is more drastic. It's a Full System Reset and Planner Rebuild. Be advised though: Your recordings are at risk!

1) Switch your digibox on
2) In sequence, press on your remote 'SERVICES > 4 > 0 > 1 > SELECT' (this will access the hidden menu)
3) Select the relevant option (usually the bottom two) and follow the on-screen prompts (note that it's likely your digibox will reboot between processes)
Applies to Sky+HD Digiboxes only, running latest EPG
1) Press Services on your remote control. 'Options' in the Top Menu will be highlighted in orange.
2) Press the Right arrow once to highlight 'Settings' in the Top Menu.
3) Now press the Down arrow once to highlight the 'settings' tab in the Middle Menu.
4) Press 0, 0,1, Select on your remote in quick succession. The 'Setup' tab will then be highlighted within a hidden menu.
5) Select the relevant option and follow the on-screen prompts (note that its likely your digibox will reboot between processes)
Sky Digibox Planner Rebuild / Full System Reset (if stuck in standby)
Applies to Sky+ and Sky+HD Digiboxes only

Same as above, but applies if your digibox is stuck in standby and you cannot get to the hidden menu:

1) Switch the digibox off at the mains power, so no lights are displayed on the unit
2) Press and hold the 'right and left arrow' buttons on the digibox (not the remote control)
3) Whilst holding, switch the digibox back on at the mains power so the red standby light is displayed
4) Wait approximate. 30 seconds for the blue Sky+ ring of lights to display, at which point you can release the 'right and left arrow' buttons
5) Press 'SELECT' on the digibox (not the remote control)
6) Now the system will format the hard drive, the blue Sky+ ring of lights should spin backwards
7) Allow the system to format, which can take 10 minutes before returning to standby
8) Try to power up!

Your hi-fi is not part of a hard drive or a shuttle computer. If you have a problem with your Hi-Fi, it would be best to tell us the make and model and ask in the Hi-Fi or stereo section.
