REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

  2. SUB CONT : For CONTRAST adjustment (fixed)
  3. BIAS R : For R BIAS adjustment (Changeable)
  4. BIAS G : For G BIAS adjustment (Changeable)
  5. BIAS B : For B BIAS adjustment (fixed)
  6. GAIN R : For R GAIN adjustment (Changeable)
  7. GAIN G : For G GAIN adjustment (Changeable)
  8. GAIN B : For B GAIN adjustment (fixed).
SAA7118
  • It is a VIDEO DECODER and used to adjust a picture quality for VIDEO/DVD(480i).

MISC TSTPTRN AT:
  • Cycled patterns from R à G à B WH every 1 minute automatically.
  • TST PTRN MA : Cycled patterns from BK à WH à R à G à B by pressing volume up key.
  • AT PWR : ON - Condition where turning AC power on, automatically turns the SET on.
  •   OFF - Condition where turning AC power on makes the Set STAND BY, and POWER of Remote-controller on turns the set on from STAND BY state.
JACK:

INFOR
MICOM VERSION.  (year 4 digits, month 2 digits, date 2 digits and time 4 digits : 200309222030 )

RESET.
EDID SET
  • [Note] Be used to set to write EDID data (After setting it is changed to “EDID DONE”). Before setting EDID, you have to short jumpers of JP710. After setting, you must remove jumpers, and then, turn off and on main power. If “EDID WRITING ERROR” is displayed, Try again. But, in DEUK, you don’t have to set EDID set (After removing jumpers, EDID DONE is changed to EDID SET).

  1. LEVEL 1 : Be used to initialize all of the data including adjusted figures for W/B.
  2. LEVEL 2 : Be used to initialize all of the data except adjusted figures for W/B
  3. FACTORY : For User menu initialization, is actaviated by choosing a language on AC ON mode. (Menu Display, VOL, OSD Background and Input mode (VIDEO 1) initialization).
PANEL
ISM : 
  • Used to minimize Image Sticking (ON/OFF).
  • ON : When Still images or regular patterns have been displayed on screen for some times, the luminance of screen is going to decrease as below. (But, only when pattern area is over 50% and it is lasting over 5 minutes).
BWINV:
  • Used to minimize Image Sticking (ON/OFF).
  • ON : Inverting the original images.(in Digital image data, “0” à “1”, “1” à “0”).  If Still images have been displayed for some periods, this function can minimize Image sticking, by displaying it on BWINV mode for some times.
GAMMA:
  • Can choose one in 4 gamma tables.

  1. BRIGHT : Adjusting Peak Luminance
  2. 100% : Full Peak Luminance
  3. 63% : 63% of Peak luminance
  4. 40% : 40% of Peak luminance
  5. APL: Average Picture Level
SCROLL:
  • Minimizing Image Sticking (ON/OFF) by Shifting whole screen BRIGHT
  • Adjusting Peak Luminance. (same with PXL SFT function in 6)MISC) ON : This function moves1~8 pixel with a regular rule, up, down, left, right every 10 sec.
BRIGHT:  Adjusting Peak Luminance.
P SAVE:
  • Controlling power consumption by changing Luminance level of whole screen.

  1. 100% : Peak Luminance & Maximum Power Consumption mode
  2. 87% : 87% mode
  3. 75% : 75% mode
  4. 50% : 50% mode
linear : linear mode(Constant luminance without regard to APL)
# WARNING!! The choice of these modes can cause difference of Power Consumption.

  • MOVING:  Setting display mode of Input channel except PC input.
  • STILL: Setting display mode for PC input.
  • [Note] PIXEL SHIFT function is solution to characteristic phenomenon of PDP, so-called “Image Sticking” problem. Leave this function ON, when displaying many fixed screen like PC screen. When this function is ON the screen will move a little for every fixed interval but a human eye can not recognize it well.
