Manner kinds collection service fashion sharp
Manner. 1 (long model)

look for a switch normal – service
its for resemble switch that used in vertical part
location is on main-pcb backside close to tuner
to enter service fashion – move to position service

Manner. 2

power on
ascertain adjustment picture on course normal (with remot)
short- ja137 ja138 around 1 second then free again, so will enter in service fashion.

change ic new memory (empty)

power off
short- then temporary ja137 and ja138
animate aeroplane
wait around 30 second automatic default data kan written to into memory


manner. 3

main-switch off or pull power-cord (electricity cable)
press and hold back concurrently vol-down and ch-up in panel front
animate aeroplane
navigation uses ch and vol with remote
exit kill main-switch (data is kept automatic)

Manner. 4 (slim with uoc box)

power on

short pin-5 mikrokontrol around 1 second and free return (or ja483 with ja484)
will press menu to will choose fashion that mengadjust (adjust fashion, check fashion, option fashion etc)
navigation uses ch and vol
wait around 4 second before move to adjustment another so that data is kept formerly automatically

change new memory (empty)

power off
short then temporary pin-5 mikrokontrol to ground (or ja483 with ja484)
animate aeroplane
wait around 30 second and automatic default data will be written to into memory
if default data fails – possibility can be caused because abl britnes too bright or there problem in abl

circuit protektor sharp 20r200 with ix3098

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.

Opening HOTEL MODE on Sharp Tv Wonder and Universe

Posted by arjun cell on Tuesday, March 8, 2011

Today the arrival tv Sharp 14W20-type universe with damage to the auto / manual channel search can not be accessed, as well as CH-SETTING.Kerusakan menu as is indicated by CH-SETTING menu that changes color to purple is normally hijau.Sebenarnya things like this because HOTEL MODE function on tv in the position ON / Off function that automatically disable the AUTO / MANUAL / CHANEL SETTING.Mungkin you accidentally combines unique buttons with a remote control for remote on top of your body fall asleep when watching TV, or perhaps because of the remote control was made toys by toddlers fix this follow these steps: first use the remote control and press the MENU button scroll to scroll back to the BLUE FEATURE BACK ON position and press and hold -/-- button for 5 seconds, then input the password 1379 then press the V + to disable this MODE.Cara HOTEL for Sharp TV Wonder / Universe which already has a feature STEREO, while for MONO features through the following steps: use the remote control and press the FUNCTION button repeatedly until the set into BAHASA LANGUAGE and press the button - / - and enter the password 1379 then disable HOTEL MODE by pressing the V +. With the steps above, the problem difficult to access the AUTO / MANUAL / CHANEL SETTING can be resolved, may be useful for colleagues technicians all, keep the spirit and success for you all, thank you.

Alexander Sharp tv standby Dead

Posted by arjun cell

This afternoon get more service calls to fix the tv in his house Dafid father / mother Harsini, Coral, Mangge, West, Sharp brand .and Alexander type 51DXF200 type with a complaint if in turn the tv would not start at all so just wrote a glowing LED lights continuously, the front panel tv did not work from remote let alone! No response was unloading my sekali.end same tv, the first step I did was as usual at the first re-soldering all the parts afterwards checking the voltage, the voltage B + which should be around 116V 150V measurable, voltage of about 20V for normaly Audio, sedangan voltage 7V to 14V drop live alone, hmm .... what's this? Then I find the heatsink for IC regulator 9V 090RD1 series is very hot, also for the diode rectifier and R boundary is also very hot at all, woow woow woow what else is there? At first I thought this regulator IC is short, but after the change with a new, still tetep only, hot and hot, hmm ... what causes it? Finally I browse all the components associated with the output of the regulator IC, I finally found the source of the problem comes from a series of Stereo / Surroundnya located on the outskirts of the main PCB, with a socket and a standing position, when I pull this little PCB from the socket, can live tv normal, but when I plug it in again, directly stanby.YESS finally met also the source of the error, the SMD type IC with type MZ-01E, but unfortunately there is no IC in the market of this kind, asked SHARP SERVICE CENTRE  no stock he said, Haduh Iki haduh haduh piye? yes I've finally cut aja L3501 IC that is connected to VCC and I try to turn it on tv, hmmm ... can live tv flawless picture and mono sound is also normal but he he is not what is important-whatever her family could've Pak Dafid enjoy tvnya again, Okey success for EVERYTHING!
