Memodif Power / Regulator DVD, TV, TV MONITOR, POWER STANDBY and others using STR 5Q0765RT or 5Q1265RT

Tv Polytron MX 14 'IC Vertical HirstBye tried to post an old case back.
Polytron MX 14 inch Vertical ic scorched and charred participate PCB and heatsink has been added, may be the case of over-heat / ic vertical too hot.
Ever wondered if maybe there koslet the vertical coil and after dismantled no signs of damage or short.
Switch IC, Elko VCC + and -, Elko pum-up 100uf results are still hot and there has been no sightings.Having traced it turns out there are dry mouth Elko C411 ic 1uf_50v that causes heat.




Damage Horizontal tv Polytron SlimThis time I will share some solution to the problem of damage horizontally on tv Slim Polytron.

• Damage to the C812 / 15N 1,6kv result in direct horizontal perforated TR / koslet marked by the death of indicators for TEG B + direct drop.• Damage to the C801 / 300N 800V resulting image is reduced to stay one vertical line and the impact on the outbreak C802 / 160V 2u2 and also can lead to TR EW T803 / D313 short and severity of TR Horizontal damaged. Ever get no noise due to damage C300n menjuit - juit Reviewed accompanied flyback pulses of voltage B + down ride her,• Damage to the C817 / 82n 630V lead to the finished image to zoom or wide television broadcasts logo just looks half.• Damage to the TR EW OUT T803 / D313 resulted when short picture so wide and can not be regulated, and if so narrowed and loos image can not be regulated through service mode.• Damage to the diode D804 / DMV1500 resulting image extends and TR horizontal heat up quickly, but if the diode koslet lead to B + so drop.• Fortunately input TR EW D313 given out so that when TR short diode does not result in damaged on the drive.• Damage resulting Flyback TR B + drop and fast heat and direct hor koslet.• A few of my little experience hopefully useful.Protek damage Tv Polytron• For the engineers who already know maybe it's very trivial because maybe they already know and can from the internet and browsing or sharing with friends fesbuk.
For the layman this might be very annoying at all so this kind of damage can be resolved by replacing the engine with engine china tv service technician or over other, more experience. This means that they are unable to cope with this kind of damage. The cause is a loss of voltage 5v pin protectionism.
Here is a picture of the causes of tv Polytron Protek, meaning that tv can be lit and Polytron logo appears and then returned to standby.•

One more damage that may still rarely see that button as if squashed so that the display panel tv is always changing, eg tv pictures sometimes appear, and then change to AV and turned again to the Radio and repeatedly so that the impression IC konslet program.
But apparently mistaking it turns out damage to C bypass / filter KEY pin to Ground.View image:•Tv Polytron power supply IC TDA8380A _ FS7UM

R 517 180 ohm always singed on TV Polytron
 It is a case of old tv Polytron I ever post but without the scheme, and is now complete with the scheme.
Tv Polytron MX 5v regulator is frequently damaged in TR T504 C2328 (1), R517 180 ohm (2) and D512 dzener 5V6 (3) even dzener 5V1 participate in panel swicth short.The damage caused by TR T505 A1023 (4) failed to break the current 38V so the 5v regulator get into areas that should only 12v (when the TV is on)The solution:• According to the solderkita.com by replacing the T506 TR C1815 (5) with the D400.• In my opinion, Because TR C1815 still good and replace the same TR also been a problem, which is just changing R519 or R520 10K (6) to 5K6 and the results are ok ... maybe power standby of programs that confer resistance grounding has occurred degradation ( mimicking the term of the pack Marsono)• Replace the D511 IN4007• Switch PhotocouplerPolytron MX52P65LI

     Polytron minimax Dipe totally dead.
After checking the damage to the power supply.1. Fuse dropped out.2. TR FET FS7UM measurable short.3. TR C1815 and A1015 too short. 12v zener diode, diode IN4743 (DZ 13V) and IN4742 (DZ 12V) measured short.4. Do not forget to check diodes B + 115v because when the diode is short then direct FET TR broken.5. Or if faulty then the optocoupler IC FET damaged.
After the replacement komponen2 without TR FET check the input voltage (G) must be 4 - 5v.And once installed TR FET FS7UM Press and TV is back OK ..


 POLYTRON TV IC TDA8361 Image is out of sync
 Polytron oldschool 14 "Image is sometimes normal but sometimes do not appear just striped lines running up and down the left and kenanan like losing sincronisasi. After checking the track AFC in the capture of AC 185v of FBT in Copel through C and bypassed by the diode and C to ground then linked with R 10 ... K 1/4 w which turned out everything was still good and still connected to pin IC TDA 8361 on pins Sinc Sparator. after soldering the parts kendor2 begin to turn on the TV and gambarpun normal again after a few minutes the image starts flashes and ahirnya back as they lose sincronisasi. Finally I ragu2 no longer just replace the TDA8361 IC bekasan surviving only damaged on the Video input for VCD / DVD. and it turned out OK .. direct TV after a long and tv unchanged still remained normal I finally bought a new IC that cost quite expensive Rp 80,000 ', there is also OM 8361 which costs Rp 50,000,' but the chance was gone. And once installed directly IC..TV OK ..! and AV were already functioning again. Similarly, just info may be useful.Damage to the TV Polytron Minimax1- TV standby because the program does not work due to supply voltage in IC program / control drop when we measure no 5V when we turn it on. This is because elco 10uf63V weakened. At the time of standby at that point they will elco No 8 - 10V and after tv live will rise to 50v to supply TR Horizontal driver.
2- R 330 ohm / DZ5,6V / TR C2328A at suply 5V regulator IC Program are often damaged due to failure of the switching TR B1186A / A1023 break the current of 50V voltage earlier, because after the tv on suply IC programs only from 12 / 14V at the output of the inverter. The solution reducing Base voltage C1815 (drive TR A1023) to shrink the R530 and R517 R of pin Power on / off ic program that had become 5K6 10K. At the moment there is a voltage of 5v OFF and ON becomes 0v at the time.Damage to komponen2 TSB can also lead DZ5V on the PCB panel buttons come short.The loss of voltage 5v voltage IC program resulted tv lit white blank with no raster with the left and right of the screen narrows.
3- First press tv power of life and there is a picture after a few seconds and then tv standby. This often occurs in the generation after minimax tv Polytron using a single IC (Program and image). In cases like this are the same as other brands tv2 due to interference on IC vertical so protectionism. Change elco which is connected to pin IC no writing PROTECT. In TSB pin there should be 4 or 5v voltage. In the vertical IC and replace elco elco 50v1uf 50v10uf.

4- Damage often occurs because the power supply DIODE R3GP / R6GP 29 inch on the voltage B + is often short which resulted Shortnya TR fet S7N60A / FS 7UM / FS1OKM accompanied by damage to supporting components bleak R, TR and DIODE.The same damage can also be caused by an optocoupler.One of replacing regulator diode in the circuit can cause the power suply drop.
5- In addition to the damage as above there are many more other kerusakan2 such as:Missing the noise caused IC AN5891K damaged, or damage caused damaged or corupt DATA.


Memodif Power / Regulator DVD, TV, TV MONITOR, POWER STANDBY and others using STR 5Q0765RT or 5Q1265RT

Before we proceed surely most of us have much to know that STR 5Q0765RT and 5Q1265RT often used in TV brands Samsung, Akira even tv china also there are disposable and STR types are widely sold in the market.
So I adopt from there and I've been practicing for others such as:• Power standby1. Once I tried to change the power standby STR Panasonic Projection TV (for hard to find) and managed.2. UntukPower standby DVD HOME THEATRE• Power supply DVD, already tried and succeeded.• Monitor, tv, tv LCD and othersWe just added some components we can use perforated or can be reversed PCB circuit / bottom.
