Servicemodesand DealerServiceTool (DST) For easy installationand diagnosis the dealer remote control RC7150is introduced.The RC7150can be usedfor all new TV sets, includingall set of the MD1 chassis.The RC7150is also called Dealer Service Tool or DST. The ordering number of the DST (RC7150) is 4€,22218 21232.

When the mains power is switched off while the set is in SDM, the set will enter to SDM immediately when the mains is switched on again'

The SDM has the Íollowing pre-deÍinedconditionsÍor all microprocessorcontrolledtuning and linear functions: - For recognitionof the SDM "SER" is displayedat the top oÍ the screen. - Tuning at 475.25 MHz (Secam on Multi-Francesets (with Nicam L), PAL on other sets). - Volume level is set to 25olo(oÍ the maximum volume level). Other picture and sound settings are set to 5096. - Auto switch off disabled (normallythe set is automatically switchedoff when no video signal (IDENT)was received for 15 minutes). - Sleeptimer is disabled. - All other controls operate normally. - When the microprocessor supports the "blinking LED" procedure (See 6.3) and an error code is present in the error buífer, the LED will blink the number of times, equai to the value of the last error code. This function will also work when there is no soud or plcture. 6.2.2.2 Seruice Alignment Mode (SAM) EnteringSAM: - By transmittingthe "ALIGN'commandwith the RC7150 Dealer Service Tool (this works both while the set is in normaloperationmode or in the SDM). - By pressingthe "MENU"and':" key on the local when the set is in SDM. keyboardsimultaneously ÊxitingSAM: - Switch the set to stand-bv. Note:

When the mains power is switched off while Íhe sef is in SAM, the set will entet SDM immediately when the mains is switched on again.

ln the SAM the following informationis displayed on the screen: - Softwareversion (the software version oÍ the microprocessorin the set is displayed.This software version identiÍicationcorrespondswith the software versions in the Software Survey as publishedin the Product Survey. - Error code buffer (see paragraph 6.3). - Options (see paragÍaph 8.4). - Alignment and geometry information (see paragraph 8.2.1,8.3.1and 8.3.2).

Note!

Note that it may take up to 7 seconds before the set respons to a DIAGNOSE contmand. lnterruption of the blinking sequence may lead to incorrect results.

lmportant!

Not all software versionsof the MDl.2E chassis support the blínking LED procedure and the DIAGNOSE 99 command. Software versions NOT supporting the blinking LED procedure are MlZBAx-x.x and Ml2COx-3.x.

Disconnect the SSP(asa resultthelinewillnot functionanymoreandthereforewill no longerbe a loadoÍ the powersupply)or disconnect the lineby removingjumper9400and R3400(if present)on the LSP. 2.

Connecta oscilloscope to testpointP4 at pin g ICZSZO. 4. Turnup the exteÍnalDCsupplyvoltageslowlyto 17V DC. Remark:

+SDb and +8Sc protectionof the microprocessor +SDb and +8Sc are the main supply voltagesof the entire small signal procêssingoÍ the set. At pin 34 the microprocêssorsenses whetherthe supply voltages +SSDbor +8SccomingfÍom the powersupplyare present.When one or both the supply voltages are míssing,the set switches to soítware protection.

Faultfindingand repairtips Note that Íor 21' sets, voltages and wave forms may differ.

6.5.3 Fault finding oÍ the horizontalcircuitry When the horizontalcircuitry itselÍ is defective,h can be simplifiedto a stand alone'switched mode supply"at low voltages (low risk) as Íollows: 1. Disconnectthe set Írom mains. 2. Discoínect the SSP by removingall cables to the SSp. 3. Conneotan eldemal 50V DC (or 40V DC) supply with current measurementpossibilityacross C2400. 4. Replacethe HDRIVE by an eliternal LF generator[fTL level (between0 and 5V); duty cycle 50olo)with a t6 kHz pulse at the base oÍ TS7410 (near LOT at the side of the PCB). 5.

ServiceModes,DST,Errormessages, 6.5.4 Faultfinding "no picture,no protection"(problemin

Thestartup phaseoÍ the setcan be identiÍied:

the video controller lC part TDA8366-4C) When there is no pictureand no protection,it is most likely that there is a problem with the BC_INFO caused by the ïDA8366, the RGB ampliÍiersor the picturetube. For measuring, connect a video generator (e.9. PM5518) at the aeriAl input with a white pattern to the tuner. Trigger the oscilloscope field ftequent. A stable picture is obtained if triggeredwith VDRIVE+at pin 4 511.

1. A bright white hórizontalline at the top; the rest oÍ the picture is darlt (sethangsin firstphaseoÍ startup procedure) pictureoÍ the voltageoverthe gunslooks Oscilloscope likefigure6.12. TDA8366(1C7119),picturetubeand RGBamplifrersare OK Thereshouldbe 4.5Vat pin16TDA8366.

Normal start up procedure 1. FirstphaseoÍ start up; 4 white measuringlines (lines15, 16, | 7, 18) and the main picture is muted (wave forms are better visible ff the picture tube is cold);

2. Smallhorizontalrcd, greenand blue lines at the top; the rest oÍ the pictuÍe is dark (sethangsin secondphaseof startup procedure)

Figure6.12: Red (pin 8 oÍ connector R43 on the CRT panel)and green gun (pin 6) 1O0V/divDC: 100us/div

TDA8366is OK

The total beam current is measured and fed back to pin 16 TDA83660C7119) The TDA8366 checks the voltage at pin 16 of the TDA8366 during these lines < 4.5V : set remains in this phase > 4.5V : set continueswith start up phase 2 2. Secónd phase of start up; each beam is separately measuredand the main picture is still muted. Line 15 is Red, line 16 is Greenand line 17 is Blue.BC_INFOis measured. - differencesbetween the lines (guns) are compensated - when the diffeÍencesare minimal the set continues with phase 3, otheruise it remains in phase 2
