NOTES AT THE TIME OF PW BOARD EXCHANGE
These models corresponded to the printed circuit board exchange in the PDP unit.
Therefore, this service manual describes only the information relevant to it.
For details other than those described in this manual, please refer to the GD-V4210PZW,
GD-V4210PZW-G, GD-V4210PCE service manual (No.51767 2000/10) and GD-V4211PCE
(No.51767B 2000/12).
It will become the cause of failure if dust adheres to the inside of a connector, or a flat wire and a
point-of-contact part.
When the PW board is exchanged, be careful of the dust and dirt of the inside of a connector, or
a flat wire and a point-of-contact part enough.

4. INSPECTION OF POWER ICS
According to the following procedures, measure with a circuit tester and check OK or NG.
COMMON PWB SCAN PWB
The allocation of power ICs to be checked is shown below.
Check the pin 4 or pin 5 of the connector [CN8] on the SIGNAL RELAY PWB (lower left).
OK: Open

Detac h the connecto r [CN8] or [CN9 ] on each of the SIGNA L
RELAY PWB s (for exampl e : lowe r left board ) and chec k the
conduction between the pin 4 (or pin 5) and the ground.
In case of "short" , one of the data ICs connectin g the SIGNAL
RELAY PWB may be defective, and you should check whether
ther e is an y trac e of damag e on th e dat a IC' s surfac e afte r
removing the heat-sink on the data IC.
