Table 1

Each kit part number begins with the acronym PSOL, meaning Protective Screen Over

Lay. Following the acronym are a series of alpha-numeric characters identifying the

screen size and intended unit type. In Example 1, “40” identifies the kit for use with a 40

inch screen size. “X1” indicates the kit contains all grids for any unit in that screen size.

Example 1: PSOL40X1

In some cases there are models with different aspect ratios within a screen size

category. In such cases, the letter “W” in the kit part number indicates use with wide

screen (16:9 aspect ratio) units. See Example 2 for details:

Example 2

PSOL50X1 is used with any 50 inch unit with a 4:3 aspect ratio screen.

PSOL50W1 is used with any 50 inch unit with a 16:9 aspect ratio screen.

Readme: The overlay dimensions are contained in the appropriate unit Service

Manual, as shown in Figure 1. If a particular overlay kit is not available, or there

is an urgent need for a complete convergence alignment before the kit can be

delivered, strings and low-tack tape can be used to achieve the desired results.

Readme: Backup data should be loaded only if corruption of the original data

is suspected or if the set is severely misconverged. Minor misconvergence

issues should be corrected by performing the appropriate alignment procedure.

To load back up data:

1. Enter Service Mode as described in the appropriate Service Manual.

2. Enter convergence alignment mode by pressing the “7” key on the remote.

3. Display vertical stripes by pressing the “9” key on the remote.

4. Load the backup by pressing the “1” key on the remote.

created.

10.Power the unit off to exit service mode.

Module No. TV-GEN-03

Page 7 of 20

TOSHIBA PJTV

Digital Convergence Alignment

Readme: Do not attempt to load backup data if the digital convergence PCB has

been replaced. Backup data in the new PCB memory is not created until

convergence has been adjusted and the CALIBRATION procedure has been

completed.

Something to think about:

It is important to know when a convergence alignment will not correct the unit problem.

If after following the correct procedure, the convergence cannot be aligned to factory

specifications, further troubleshooting is required. Table 3 lists a few of the many

possible symptoms.

Repeated Touch Focus errors

Intermittent loss of convergence

Repeated convergence drift of any color

Selected color will not adjust in either direction

Convergence crosshatch pattern will not display

Convergence crosshatch pattern is severely distorted

Touch Focus pattern is not displayed

Touch Focus pattern is severely distorted

Back up data will not load

Cannot enter Service Mode

Data cannot be saved after alignment

Table 3

Points to remember:

Familiarity and practice help the technician develop confidence in performing a digital

convergence alignment or determining the need for further troubleshooting. Having the

knowledge and necessary tools available are an important first step in the process of

gaining experience. While taking this first step, it is best to follow the alignment

instructions carefully and exactly. Back up data, if available, is a useful tool if problems

occur. It can provide a good starting point in certain cases, but it should not be viewed

as a “cure-all” for convergence problems. In most cases, only minor adjustments will be

necessary. Focus and centering adjustments will not be needed and the procedure can

begin in the GEOMETRY stage. Minor adjustments made in this way do not require

the use of back up data or an overlay kit. Simply make the needed adjustments, save

the new data accordingly, exit the service mode, and you’re outta there!
