DAMAGE REPAIR TELEVISION EXPERIENCE

 

LG 21 INCH BLACK PEARL RED COLOR ALL HIS SO, PTC IS CHANGING, AND TR C2330 N HIS REMAINS THE SAME RESULTS ?

                                                            SOLUTION
try to measure its output in  rgb oscilatornya output voltage when the 3 rgb over her on the red rgb try its factory settings remain the same if  ic osc replace it with a new bsa so ic is damaged

Polytron HBT 00 04G LED indicator continues to blink blink ..?
                                                           SOLUTION
Led blink blink, the voltage is also up and down, TR Horizontal Ok, FBT has also been replaced, Elco all okay (measured pake and capacitor ESR meter) whether the IC program with problems ..?
-  Check this voltage 5V and 8V eastbound HBT slh one leg may be TR, zenernya diode die, I've also   
   experienced the damage caused by the vertical ic dead and rather worn 1uf50v elco 402 c.
- try the tripe out 5v line, I have experienced similar damage to take 2 days, as good as tested components are
   not damaged, but when lit was experiencing voltage drop
   try to replace the elco, zener diode voltage and the coupler on the ac-matic

Diva TV Polytron Type PS 52V60 kira2 concave sides of what ?

                                                           SOLUTION

in my experience, positive elco elco c511 c401 positive jumper to TEG 5 volt, typically straight okay

I try to love HEATER external voltage .. if observed only once on a while the picture looks like a jagged lightning image in the middle ... There are other clues ...?

                                                           SOLUTION

Well if so could jd Chromanya IC, but not yet. Check voltage wrote first of all. Disconnect from the CRT HV SMPS Out to be good at all.

B +, Audio IC, TR Horizontal Normal. Bias Teg Hor of existing IC (5v).
Fly back but did not work. Could terprotek? but where?.
Maybe anyone have temen2 sekma / Chassis 21AXS250E this solution, IC Prog TDA12156H1/N2/3?
PROTECTION OF THE SHARP TV (TDA93xx) AND CODE blink
- TDA938x-IX3410 (wonder), TDA938x-IX3386 (universe)?  

                                                          SOLUTION

Protectionism / SENSOR ON TV SHARP 

As I recall the author, has long, sharp tv products are equipped with protection systems. If found irregularities / abnormalities, tv will protectionism by itself (for the security / user). And now, almost all TV brands also use the air-protection system. But when compared with proprietary protection sharp tv, no match. Therefore, the authors do not be surprised if a scourge for tv sharp tv repair shop.
Almost all parts / tv sharp block equipped with sensors and the type of protectionism by different methods, among others:

1. Sensor voltage: v heater, 115V B +, B + vertical, 12/16V and other stresses. Overvoltage protection   consists of overvoltage and NoVoltage. Components typically used for sensor voltage using diodes (zener / diode usual - 1N4148).
2. Sensor Output / input block: vertical output (Vertical Guard), H sync, etc.. TV will be protectionist if no output / signal or in the form of DC output voltage.
3. Sensor Sync: although rare, this protection is usually entered in the jungle IC / chroma.
4. X-ray protection: censor the ABL voltage, serves to censor the HV voltage (because ABL is minus HV).
5. and most recently, digital data protection. Because the circuit is designed  as possible (made ​​in one chip), the protection system is also incorporated into the IC. IC-ic is scheduled to send data to the IC-program if the system (in the ic) there's something wrong, then the program will protect ic / tv turn off the device.
