WARNING ( KV-21M1L/21T1L/21M1U/21T1U only )
The flexible mains lead is supplied connected to a B.S. 1363 fused
plug having a fuse of 5 AMP capacity. Should the fuse need to be
replaced, use a 5 AMP FUSE approved by ASTA to BS 1362, ie
one that carries the mark.
IF THE PLUG SUPPLIED WITH THIS APPLIANCE IS NOT
SUITABLE FOR YOUR SOCKET OUTLETS IN YOUR HOME.
IT SHOULD BE CUT OFF AND AN APPROPRIATE PLUG FITTED.
THE PLUG SEVERED FROM THE MAINS LEAD MUST BE
DESTROYED AS A PLUG WITH BARED WIRES IS
DANGEROUS IF ENGAGED IN A LIVE SOCKET OUTLET.
When an alternative type of plug is used it should be fitted with a 5 AMP
FUSE, otherwise the circuit should be protected by a 5 AMP FUSE at the
distribution board.
ASA
T
How to replace the fuse.
Open the fuse compartment with the
screwdriver blade
and replace the fuse.

• REMOVAL OF ANODE-CAP
Note:
Short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield or
carbon paint on the CRT, after removing the anode.
* REMOVING PROCEDURES.
a
1
Turn up one side of the rubber cap in
the direction indicated by the arrow a
2 Using a thumb pull up the rubber cap
• HOW TO HANDLE AN ANODE-CAP
1
Don't damage the surface of anode-cap with sharp shaped material !
Don't press the rubber hardly not to hurt inside of anode-caps !
2
A metal fitting called as shatter-hook terminal is built into the rubber.
3
Don’t turn the foot of rubber over hardly !
The shatter-hook terminal will stick out or damage the rubber
b

REMOVAL AND REPLACEMENT OF THE MAIN-BRACKET
BOTTOM PLATES.
For safety reasons, on no account should the plates be removed
and not refitted after servicing.
— 19 —
(1) REMOVING THE PLATES
In the event of servicing being required to the solder side of the D Board printed
circuit, the bottom plates fitted to the main chassis bracket require to be removed.
This is performed by cutting the gates with a sharp wire cutter at the locations
shown and indicated by arrows.
Note : There are 5 plates fitted to the main bracket and secured by 4 or 6 gates.
Only remove the necessary plate to gain access to the circuit board.
FOR SAFETY REASON THIS
PLATE MUST BE REMOUNTED
AFTER CUTTING AND
TAKING AWAY.
Fig 1
(2) REFITTING THE PLATES
Because the plates differ in size it is important that the correct plates are refitted in their
original location.
The plates are identified by markings A-B-C-D-E on their top side.
1. Identify the plate by locating its marking.
2. Turn the plate over noting where the marking is located.
3. Locate the corresponding marking indicated on the main chassis bracket. See Fig 2.
4. Refit the plate as indicated in Fig 3 with the markings located next to each other.
FOR SAFETY REASON THIS
PLATE MUST BE REMOUNTED
AFTER CUTTING AND
TAKING AWAY.

2. (Moving horizontally), adjust the H.STAT control so that
the horizontal red, green and blue dots coincide at the
center of screen.
3. (Moving vertically), adjust the V.STAT magnet so that the
vertical red, green and blue points coincide at the center of
screen.
