Sharp TV universe that protectionism

Posted by arjun cell on Tuesday, July 29, 2014

Nearly 4 hours made ​​dizzy by sharp universe, so complex protection system, langakah to overcome the sharp tv universe Proteks, please refer to either - well my story below,
Incidentally sharp tv universe can service TDA9381 IC / IX 3368, said that had the tv, lights lednya not as usual, was that if a flame red color standbay green, LHA is why the color is so yellow, and can not catch the broadcast tv, just get to watch vcd,
after the owner can curhatan from now I try, it turns yellow berwarana lednya Ko, instead of the screen can not live aka dark
owner vent again, it was the most damaged mas lights ...
hmmm '' ... !!!
After loading it directly aq, well it turns out really gross profit in it many homes 2 & dusty black
Now it's time for action, 'see ya good either'
The first step is to clean all the dirt that is both dust and earnings spider, use a brush, as well as his tv motherboard, to the motherboard (PCB) that is used to clean the copper lines using paint thinner, paint thinner good use,
after we cleaned with thinner re-solder it all starts from the regulator power supply
Once completed we re-solder all the time in on again. good.Jreng pray ... still do not want to live TV led      
yellow LED if it might be because ic memory error or corrup
Replace the memory IC 24C04, after ic memory in dressing now in his tv jreng try again ...! red LED ni wah good sign, immediately push the power on in the remote, the LED turns green but just for a while only a few seconds, waaaduh ... ass again nich. If the red LED then berwarana reddish green and back again or standby means terprotek tv, tv terprotek because there could be a slew voltage up or down
Protek foot pin IC TDA9381 IC / IX 3368 at number 8 3,2Volt normal voltage or 3.3 volts

then locate the point where that happens protectionism by releasing one - by one diode protection "for shortcut to remove all the protection by removing the jumper 223", and met also turns off when the D503 vertical ic voltage protection for the tv after tv in on the flame, and it turns out there is slack in the foot solder elco 100uf / 63v directly re Selder, after trying to re-solder at the moment and keeping new 5 minute tv standby lED changes color again ... what else ni merah.waduh
tv in onkan tetep happen again could not protectionism, jumpers off 223 I can be on tv led green but the screen dark tetep tetep not flame heater, horizontal osc worked briefly then off but the led is still green sign tetep berwarana tv on.kemudian I put the jumper again 223
try to enter the menu faktori, by way of a short two jumpers sort 122 to 124, tv flame but also tetep briefly returned to standby
From the dizzy and weve already dizzy, I replace all the filters elco for supply voltage and the results remain the same protectionism standby.woow ... wait - wait, I take a break for a few days stay hope to meet again the idea
Use elko size 470uf / 35V I try, one - one with a parallel manner in cacis on foot Elco ic supply filters in each path, and it worked well not have thought - would have thought it small elco petite size 100uf / 6,3v as the culprit, located at the foot lanes 3 TA48MO33 3.3V regulator ic, whereas in physically look good, in measuring the voltage on the line also good, ie 3.3V control ic also be working normally at the time marked on the button on the remote at the tv could push the flame though briefly, the current position may want to flame voltage drop occurs. 3.3V voltage supply ic used for control, without the tv on onkan voltage can not, in the remote also will not be able to,

circuit protektor sharp 20r200 with ix3098

  • sharp 20r200 with ic program ix3098 and chroma m52340 be old fashion, but sometimes still there that enter ketempat service.
  • this model is to steps into service fashion uses a switch (s1006) the location there membagian hind main-pcb near tuner linked to pin-37 ic program. to step into service fashion so position switch mempindah to “service” to menshort pin-37 to ground.
  • ic has pin-protek input in pin-38 program, where in the tension normal condition “nol”. to paralyse protektor so pin-38 can menyhort direct to ground
  •  circuit protektor relate to tension heater from flyback


there 3 condition kinds that can causes protektor active work, that is

  • first x-ray protektor that active if tension flyback exceed normal. if tension flyback over so will causes tension heater also will come to rise so that causes zener mengode d610 penetrated and pin-protek get tension “high”
  • second protektor that active if tension heater drops or lost caused among others for example because flyback broken, horizontal part problem, or def yoke short. tension heater drops or will lost will causes transistor collector q603 there tension “high”. normal tension in collector q603 “nol”
  • third (this matter stills question mark for we) problem ic memory


experience 1.

  •  technician friend ever see difficulty (asks to we) with problem protek in this model. circuit protektor inspected there is no problem. memory has been replaced.
  • obvious problem caused because vcc ic program a little drops. the cause capacitor bypass in stripe vcc 5v a little short (leak)


experience 2.

  • this is experience kamisendiri. after aeroplane at “power” - a moment then green indicator lamp will turn red and glimmer
  • but -power again – led green meyala again sebantar – and then turn into red and glimmer again
  • ic also circuit protektor there is no problem. even circuit protektor paralysed.
  • surprisingly when switch s1006 in mempindah on course “service”, aeroplane can normal alive – flame green indicator lamp then. and if switch be returned to normal position – led red winks will to return
  • after dizzy seven arounds 2 days mengubek - obvious problem lost self when do we do re-solder in x-tal oscillator ic program.

sharp with tda9381 there is no picture, normal voice

Posted by andaripa cakep

case:

  • sharp with tda9381
  • problem there is no picture and raster dark
  • osd appear
  • normal voice
  • picture cheque via av-in permanent there is no picture
  • analysis:
    • this case differs from problem “raster blank”. where raster same dark, but in case raster blank osd doesn't appear
    • here pin-rgb out measuresed all in once tension, in case raster blank pin-rgb out tension all zero
    • because voice stills there so mean part tuner and video if still ok.
    action:
    • from analysis result after study skematik, so suspicion falls in circuit abcl (automatic brightes and color limiter)
    • tension cheque in pin-abcl there is no (normal around 3v)
    • tension cheque abcl in pin-1 foot flyback – needle deviates towards negatip. normal must there tension around 4v
    • conclusion: resistor part abl to suply vcc certain in that broken off.
    • cheque r604 broken off
    • pin-1 pin-abl flyback
    • r605 get tension from b+



Note:

  • damage there is no tension abl the phenomenon in model other not yet sure same. for example in la76810 there is no tension abl causes thin contrast and can not mengadjust.
