sony tv power supply rapair techniques


Techniques through the power supply. Sony.
repair the power supply in Sony KV 2165 MT is usually not difficult, but if there is an explosion. Of the device. When the power supply. Styling ... shall be subject to long. This is chilling me if we get rid of the waste, not put on the IC's Sci Chongqing STRS6307 to this work will be bombed twice repeated three certain
cases, this has been sent in from friends so when the battle comes. No solid plans to print the piece. (Not bragging), I have compiled the repairing process model. A real treat to see step 10 emphasizing the resolution is considered to have 10 steps following this
one. The basic procedure before repair.
2. Conversion process. Transistors large the transistor chip
. 3 steps to measure IC OPTO or IC to control the six leg
. 4 steps to measure IC SE115 (EREOR AMP).
5. process measurement IC and science Chongqing STRS6307.
6. process testing department. basic power +300.
7. The real test by the IC STRS6307 dimmer light
8. Process control systems, fire
9. The 100% inspection with inspection plug light.
10th. Process equipment waste as a storage and work
to see that I can share it all are 10 steps to get to understand each topic and can also be applied and used instead of other more really. spell of reading .. then its success is as follows.
1. Be mindful of yourself that are committed to fix it by indefatigable
2. When finished reading, read it at least three times.
3. learned the principles of the book that each thread will have something earthy.
4. Everything you need to repair your own hands with the others do not use it.


When I received, I have determined the device is on the boards that there is some damage and to extend any of the symptoms we'll need to review carefully. IMPORTANT Do not be impatient gradually gradually go
meter needle tool I use is a cheap price of around $ 350 is sold in the market but it will not be distorted and precision it. Another meter is a New York mental FLUKE 11 brands which have already sold out to a new generation as the FLUKE 111 price is around 5,000 to 6,000 baht / machine interface, I find myself no longer available. Themselves that are not full.
1.IC STRS 6307 (shot between the legs measure by meter 1,2,3 I New York I).


2. C 607 explosives shattered the following values ​​= 0.33 UF himself look like it.

3. R ​​= 0.47 for the 625 ohm R fuses as I measured with a digital meter.

Position 608 is 3.1 R = 220 ohms.

Position 622 is 3.2 R = 0.47 ohms.

4. OPTO PC 111 waste leakage (measured by the meter needle).

Five. Transistors Q 601 and Q 603 transmitters and leak measured by the meter and the second is not.
inspection will find themselves all 8 it was a hard lot to repair it would take me to. ideas to repair it so that it continues to provide the greatest benefits I personally do not like it here, but I think in terms of practical features. Some people complained that I simply want to say that even if it has not already seen it, it has to give up this profession. But I will say that the "new wave old wave will come out." like us. I still do not see the importance of a film, but I do not because I know that it is very important for kindergarten or not ... let it all come together to create knowledge for diffusion. Everyone gets to know everyone. I also want to push it to the technicians know the most and I support my country.
Conversion transceivers are used instead of the little monster that it is necessary, especially in the provinces.Opportunity to purchase a router chip transceiver that is difficult. (Almost impossible), so I find the way I see it the second transceiver to transceiver use a multi-purpose router. Cheap, easy to find, very 
first. kind PNP using the phone number A1015 chip figure shows the transceiver Manchester.
Two. Shaped transceiver Leinster general characteristics are sold general
remarks.
1.1 transceiver Leinster begin with 2SA, 2SB is the PNP (Japanese).
1.2 transceiver Leinster begin with 2SA. a high to very high frequencies.
1.3 transceiver router begins with a low to high frequency common 2SB means the sound.
Two. Transceiver router type PNP (C-chip) Q601 transceiver router type NPN (C-chip) Q601 (modified type transceiver Leinster wrong).
Notice.
02.02. Transceiver Leinster starting with a type 2SC and 2SD NPN (Japan).
2.3 transceiver Leinster starting with 2SC will be high to very high frequencies.
04.02. Transceiver Leinster starting with 2SD use medium to high frequencies.


Of the incident transceiver router and then plug it with wit little shock. So I grabbed the transceiver router near the hand as shown. When the installation is complete, do not forget to use the glue gun stick again.
Because the measure OPTO very important to decide whether this is good or bad OPTO. Serves to separate heat and the altar podium cool off on the release to avoid electric shock to users that we see a version of the PC111 OPTO do better than that Ahmadinejad is the second one will use it interchangeably. ..
We'll see how the legs of the first, then there is no point Simard called black leg one the next time I see the picture. We see the internal structure afforded OPTO well.
How to measure
the meter needle is best set to Rx10 K I measurements to pin 1 and 2 of the IC OPTO note
1. bring the meter red meter leg one black pin second pin is required. up
2. put a meter black measuring pin 1 red wire tap on pin 2 pin will be up
(case 1 if the needle up a little bit, it indicates that the thread).
3. put a meter red measuring 4 pin cable. Black Temple Tea 5 needles are not up
4. bring the meter red gauge pin 5 black line measured at pin 4 pin to the number 40 or 400 K ohm
is seen as a simple thing that we should not look. skip it. We have trained very good at this task. Most people do not know much. I know less than people who do not have one ... "Well, I say" Oh .. I use PC113 PC111 instead.


Episode 5 Measurement IC STRS 6307.
Measurement IC STRS 6307 is considered as the heart of the system is the same if the error means. Blow fuse at the same exact way I would like to present a simple but effective too.


When we receive it, we see that the position of the legs.
1. COLLECTOR.
2. EMITTER.
3. BASE.
4. SINK.
5. DRIVE.
6. OCP.
7. FB.
8. INH.
9. VCC.
legs are important and should be considered the third leg on the 1,2,3 (as in switching. general) to meter to measure it.



STR S6307 with measurement meter needle
to the other leg a little problem, we propose to measure fertility on three legs, we see the internal structure of the STR ​​it.
process measurement. The meter needle to Rx10 it.
1. because pin 2 to 3 to R is 1 when measuring the second leg will be approximately 50 ohms post.
(but in fact it is a diode with inverted end well when measuring. With Circuits have found a diode that two heads).
2., when the meter black to the pin 2 and red to pin 1, pin to the number 15 or 150 ohms it.
3. located meter to R 10 K. I put the black wire to pin 1 red pin 2 meter needle will not go up ... I will not repeat the dose here.
mistake of value, it is somewhat dependent on each meter. OK, it's just a little bit away from it.



Now, with the aim of making the initial +300. V. .. to ensure it.
Principles of switching to a proportional 1:1 means that the power input into it. Output is the only example I can fire 300 to + 100 volts Bay output if the control light will be + 100 v. New Jersey as well, this is proportional by about
me. led dimmer lights that I built myself. (Unlike the dimmer lights are sold) to the picture below.


I used size 60 watt bulb comes with the ROM that C + 300 C 604 locations below to replace the load.

Open switch. (Do not forget the good old plug with a single R 470 ohms will burn) and then adjust the lights dimmer, the lights have 125 volts across the tube as shown.

While I can see that the light bulb is lit. The primary power supply is there. If the problem occurs frequently. Summarized as follows.
1. lights fuse immediately caused the PTC position THP 601 transmitters (shake to see if there's broken).
2. caused by diode bridge shock position D 601.
3. resulting from IC's switching the position number IC 601 STR - S 6307.
was asked to try to study works well for all brands gradually apply it wholeheartedly.
