RGB Cuts / RB Drivers
Mulitple sets; Direct views have GB Drivers rather than R Driver; Centering of controls on
80 series and newer requires Key to advanced menu |
Minor Decoding parameters
found in H95 & X81's but may not have enough range … CLT and CPH labels |
Three Yellow / white wires connected to
board of three crt's. Better to pull the gray white power wire on center board.
Newer units glue down the yellow/white wires. |
Done with the focus
block…read block before twisting as some upside down |
String method from
front of set for most except 43" which is from behind.; Should not have to rotate
CRT's 180 deg. |
Usually needed |
Multiple Grids on H95
to H80 series.
Single grid for H81 and newer.
Don't Touch VPOS on X81 series 4:3 sets; you may not be able to center vertically with
Vpos, use Vcen instead |
Restack or remove on
all except 83 series
HDX units; unplug Touch focus to remove frame; screen taped lightly with scotch tape;
ALL BRANDS: If removing glare screen (vs restack) use 1/4 foam weather stripping to
tighten the stack. Lay stack face down a flat surface and put paper between the stack and
the flat surface to keep the stack from sagging prior to retightening the stack / brackets |
H80 series units need cinema 7 remote to
access ADDR menu; 70/80 Series need to check if 3:2 pulldown active in TV;Grounding wires
on some HX81 and 82 series behind speaker panel; Current 83 series prone to ghosting |

RB Cuts / RB Drivers 480i only; 480p is
done with a mix of 480i drivers and 1080i cuts parameters |
Two Parameters |
Red and White wires;
shut off from user menu in
post 49/51 models |
Glued - Be careful |
Behind Set - Open back
and reach in |
Usually needed |
Use Coarse to center
image; use Fine to fine tune;
If over scan is < 5 % you may notice "screen rip" on the left
vertical edge. Move the image slightly to the left |
56" restacks from front;
smaller must take entire
top off to access front
screen; screen taped with scotch tape. |
Don't take vertical overscan to less than
5% or so; need an HD signal to properly set up 480P |

In Service Menu; Detail
item may remove EE;To minimize EE / ghosting: turn SVM down, max up on detail, then
adjust sharpness down |
Done with the focus
block … read block before twisting; may cause grayscale instability to occur |
Front; slide full screen
left and right to reach crt's; on 3 series … must use strings |
Most do not need this |
Separate grid for all
modes, Center in DFA mode |
Elites remove from front;
take frame off for regular units; Elite glare screens easily removed, non elites must be
restacked. |
Beware of removing frame bezel on sets -
may be tight and can crack frame; don't use 1080i upconvert mode in newer sets as it adds
artifacts to DVD playback |

Case by case basis |
Do not reduce horizontal
overscan to less than 5% as the sets are quirky. Watch for wavy grid lines as once
they start appearing, may have to abandon work and shut TV off to reset. |
Magic Focus wires
attached to S series bezel. Be careful. Screen taped with black nylon tape,
some pieces glued together with two sided tape; 65" must do focus from behind the set
(no hooks to raise screen up); many screws to remove to do glare screen removal., use
weather stripping to shim; 65" Hitachi: only 8 screws to remove stack, no way to
shim, must do a restack...becareful to keep dirt and tape residue from between layers |
Keep eye out for pastel
