Hornby turntable

From what I can remember when I had one of these,
if you put a small flat screwdriver in the 2 slots at each
side of the top deck and gently prise outwards the deck
should lift off.

Might help

Thank you very much Rog (RJ) for the service sheet. Extremely helpful. Thanks also to Davreb05. Finally managed to get the lid off. With the help given I was able to get the gears sorted out. The "grease" (more like glue!) in the unit was adding resistance to a area that the unit was having a little struggle with so combined slowed the motor right down. Cleaned it all up and lubricated everything. Runs well now.
What you achieve in one hand gets taken away in another! Found now that one rail on the TT is not receiving power. Checked conductivity through the tabs on the inlet track so the problem is not the contact between the tab and the rail. Looks as though that the TT will have to come out after all. Thanks to all for your help. Got it running only to discover a further problem.
Just had a thought. Might be the contact of the rail on the TT to the supply underneath. Back to the Engine Shed to check this out.

Tried the check on the rails on the TT. The fault must be inside. Checked the continuity of both rails. One was okay. Turned the TT round by 180 set and the other rail was then faulty. So it would seem that the one supplied with one polarity is at fault.

Just an update.
Managed to get the TT apart. Had to lift a few rails, took my base out from underneath, unscrewed the centre screw and then managed to take the rotating section out. A test on the centre contact strips indicated a discontinuity between one and the incoming rail. Further inspection revealed a dry joint on the supply at the contact strip. A new lump of solder sorted this out. Thanks again to Rog(RJ) for the service sheet as this gave me the detail of what the inside of the TT looked like.
Pity a simple thing like a dry joint from a professional company has caused a lot of pain to sort out. I must add the concept of the overall TT is quite ingenious in its simplicity on how the track lines up and pauses at each possible rail inlet and outlet.
I have included the update to complete the whole story so that if anyone encounters a similar problem there is is solution there.
Now back to repairing the "damage" I have done getting track and TT out.

Thanks for the update. Glad you got it fixed.
