[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]If the marking lost 1 (JF050
1-2515 ) is HR8730.
8029 to 19 chassis is ( for the diagonals more than 21 ") .
Look on the diagonal is less than or equal to 21 " - puts 8730 .
If more - 8029 .
JF 0501-2515 = HR8730 yes it is

flickers in time with him, but if you close the conclusions of
optocouplers (not from the hot side ), then the PSU enters the all
naprugi output in normal and normal on in the operating mode. tell my
people know what this could be the reason . optocouplers changed .
First, find out where ganch sits in the primary or in secondary housing .
Raise thyristor , or loaded on a light bulb 25 -40W. See how behaves PI .
In general, this topic is beaten , poroysya in the search.
By the way check quartz 3,58 (NTSC).
Try to put optocouplers with a lower CTR
about pisishki opornik teelpeshka or es eshka , or harness .
Are you talking about? Explain please, or we villagers do not understand .
The TV hush lok supply all the voltage jump
check food (st92195c7b1/oee), if it walks in the range 0 -3v, then I percent.
if there is a stable 5v , then check an external stabilization
check quartz 3,58 (NTSC).
And you have all these tips to repair BP ? ?
You optocouplers ( LED in it ), that is in control? See his administration.
pisishka - optocoupler
opornik - The voltage for adjustment
teelpeshka - it is aenka , steering errors , crap tripod 431 ,
es eshka - previously used SE110- 145 .
I finally can , it is also from the village , as all this is explained by the scientific tried obyasnt . Got it?

Conder
has changed in the secondary housing , tl431, but interestingly enough I
was shooting instrumentman and when soldered back tsykane stopped. I
have since D802 BA159 voltage jumps on the oscilloscope looked too

What are the impulses at the S829 ? Expressed himself more precisely.
You thyristor raised ?

What do you mean what ---- D889.
[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة] Changed to that fig Conder , often buggy .
And to know why raise the thyristor then go down to the search, it 's all there.
You PSU on a bulb sinkers ? ?

TV is almost new , burned diode D605 - BY228 replaced by an identical and D606 - UF5407 replaced by HER308.
I suspect that the configuration menu is not suitable for STV2248C.
Tell my how to enter the menu and change the options for adjusting the horizontal, vertical, and a pillow with the two sides .
"Menu " , 4. 7, 2, 5. Then it seems the red button. and everything is clear.
In
the menu came . The problem of such interpretation can be seen the
parameters options and last letters of their names. The top ends in SD.
Assuming from it which lines to change ?
Try the green button in servise.Dlya ak 36 rolls .
Green
Button has helped, and then that's what. Vertical adjustable,
horizontal as bonded and parabola is not regulated . Found the scheme .
What does the STV9306, can she covered ? Read the literature no .
Well, if there is no way out of , you can probably just too lazy to use search engines .
There
were a pre-sale repairs once two TVs are not out of the store , but
from another service center . They did not repair , so as not waited for
spare parts from the factory . Flaw - do not have all functions. We
opened both the TV. proved faulty D- 605 BY 228 and Q601 BU-2508AF. The
reason for the breakdown was a defective throttle L603 1mH in the chain
of EW in both cases. Crash ferrite , and therefore sozhenny winding the
throttle on both TVs. The original reactor was replaced by a homemade ,
wind it on the same frame of ferrite 2000.
Two sections of 78 turns
of wire 0.33 to one side and two sections of 78 turns in the opposite
direction. The ends of the windings soldered in parallel, as in the
original. Now , both the TV work , but the image on the TV screen size
has increased , so that the letters menu beyond the edge of the screen.
The image has barrel distortion - the image pitcher . Field-effect
transistor Q602 BUK444 defective . Have increased nominal capacity of
S627 with 0,47 mkF to 1,47 mkF - the size of the image came back to
normal , but barrel distortion survived . Adjustable via service menu
did not help . Who knows what 's wrong? Please answer a little more ,
without shortcuts.
check reistor 2.7Om in the chain of BUK- 444.pri defect L603 podgaraet.a new L603 turned 1mH.
than can be replaced BY228

In
what place there is a resistor to 2.7 ohms ? ? If , on short to short
container S648 3.3 uF at 160 volts, then the image on the 2-3 per cent
increase in size uniformly in all directions. Parameters of the throttle
is not measured , but the installation is consistent with the same
second throttle absolutely no effect on the image.
We tried to parallel the same reactor set - also no change of the image.
what
are you worth of short circuit in the OC. I wrote about a chain of E /
W.rezistor 2.7 ohms in the circuit between the diode modulator and BUK-
444.
if the radiator BUK- 444 cold it does not receive signals. I
have to work now, 11AK19-8A , and also the problem with the coil . Check
the inductance- slip off a lot of questions . I have a new 1.000mH.
what parallel / series another does not change suggests about its
unsuitability .
When it comes to resistor R612 in series with the chain L- 600 15mH and runoff Q- 602
BUK-
444, then we are in the denominations of the plant is not on the scheme
- for example, R612 for 33 ohms , and resistor R689 which vmezhdu drain
and gate at the Q- 602 - instead of 10 ohms is at 5.1 ohms. labeling .
Most likely choke L- 603 1mH all still must have accurate winding data .
But, at the plant it now
stock no .
The same problem , rewind L603 size bolshoy.Esche can add something that voltage from the
diode
modulator is underestimated and because of this chain of E / W not
working pravilno.Vse thought too about the throttle. Who will have the
opportunity to throw the other , write to reassure ( soul )!!!!
And initially the distance between the ferrite was about 1mm .
Throttle changed at TSR 1-1 ,
this izvraschalsya.I not to be confused 11AK19 and 37, they are different.
The original reactor was replaced by a homemade , wind it on the same frame of ferrite 2000.
Two
sections of 78 turns of wire 0.33 to one side and two sections of 78
turns in the opposite direction . The ends of the windings soldered in

Can the magnetic field of 2 windings vichitivayutsya ? Already prompted by becoming TSR - 1. [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

Cause of the defect was found in a makeshift
drossele.Prichinu so - have karskas from the old throttle and wire
wrapped so what was at hand ( 0.33mm ) in one side of two sections of 75
turns in the opposite direction , too, two sections of 75 turns and
soldered them in parallel . Vytkiv had to wind the wound was less than
at the factory ( from 78 turns ) otherwise would not go . According to
the theory of the exact number of turns on Q drossseley affects slightly
- much more important than what is used in the manufacture of ferrite
choke .
Therefore, carefully collected all the remnants of the native ferrite and glued them as superglue = =.
They put the throttle on the board and to handle a service menu barrel distortion .
Now television is on the run - but there is one but
whether
in working condition bask ferrite drossselya ? ? By the way sink
instrumentman heated too - hand suffers 10-15 seconds . This is after 20
minutes run . Maybe these ferrite chokes torn from heat ? ? In any
case, the perimeter of ferrite wrapped it in 4 layers of duct tape .
Everything.
Adding
to the previous one. Corporate throttle at 1 mH to get hard - they are
long gone , even in stock plant. Therefore the yield is only one rewind
choke on the same frame as described above 0.3-0.33 mm single wire
winding on two sections in one direction for 72-78 turns and winding
back the other two sections of 72-78 revolutions sealed their paraller .
Then all the pieces of ferrite carefully glue superglue = = so that the
glue would have dried up . Next, if there are some small chips of
ferrite and difficult to put in place then , after bonding the ferrite
around the perimeter of frame must pull him with a material that is not
afraid of overheating and rupture of the high temperature . In this
case, the new home-made throttle does not burst from the heat . And the
TV will work fine . Possible small distortion of the raster in the
corners of the screen . Visible only when you connect the generator test
signals.
Interesting all the tips than replace the throttle of
the domestic corporate counterparts ? ? Here are tips to try to change
our corporate throttle throttle
DRT -1 -1 wound on the same block of
line scan MS-3 from our TV 3 USTST . We tried not come. The effect is
the same if the reel homemade throttle at the same frame but with a
ferrite with pronitsemostyu 2000NM . Throttle is not included in the
saturation and it and the radiator instrumentman remain cold. The TV can
operate for days but the " barrel " better " pitcher " remains, as it
does not regulate the service menu.
P.S.
In the forums there is a new board than to replace the corporate choke - choke supply DC -1
from UPIMTST leaving 1 / 3 revolutions . Who will test result please ! |
Hello
. Once again, the replacement of corporate choke L- 603 1mH in chains
EW large -diagonal TVs VESTEL and clones . We found the most simple
reshenie.Pokupaem exactly the same frame with 4 sections and W shaped
core 2000hm, consisting of 2 halves of a letter S. Then pulls the two
sections of 75-78 turns of wire 0.3-0.33 mm in the direction of
clockwise ends the first winding of two sections Seal to pin on a frame ,
then shakes his second of the two winding sections of 75-78 coils of
the same wire in the opposite direction and the ends of the second
winding Seal to the same two pins. The ends of the ferrite is not glued
together yet. Then instead of the capacitor in the circuit S627 PL- 601
0.47 mkF x 400v ( on the scheme is marked as 0.82mkF x 400v) solder in
circuit board capacity to 1.5-2mkF x 400v. Installing a larger capacity
in the new home-made throttle reduces the size of the image. Next.
Begins to decrease ( select ) constant throttle podkladyvaya between the
ends of W -shaped iron plate from the PCB . Some within the total
thickness of 1-1.5 mm with both storon.Posle what we see that the "
barrel " is adjusted by remote control through the service menu. Then
glue the choke.
Or wraps around the perimeter of duct tape which tolerates heat . Throttle set at cost.
Homemade throttle compared to the brand is heated much less than about 40 g Ts
Radiator instrumentman also runs cooler . Picture
on the screen when applying the test signals on the " good " . The windings on the throttle swung in bulk in your hand .
Then fine tune the accelerating voltage G-2 Flyback transformer on the smaller side (turn at 10-15 degrees counterclockwise
