Sharp TV

The constraints that are often experienced by sharp tv model is protected. stanby live awhile ago. such damage is caused because the voltage on one circuit there is a drop. try to pull the pin voltage solution in each circuit, eg voltage vertical IC, tuner, video, chroma IC could also be from the heater voltage. If the above steps have been done but sharp tv blm also try hanging flame ground pin on IC601, usually turn on the TV series CD90RDA1 ago. if tv sharp flame under normal circumstances can this IC should be replaced. nice sharp tv again.

Sharp New Flat Gamma Problem

series NEW FLAT GAMMA is sharp, has a regulator with the major components STRW 6754.Menggunakan FBT by type: BSC25-0232A.Disini I took a sample of type 51AF200MS SHARP.
Who have a grievance who is very annoying in my opinion, that is pesawatTV never last long, if it is hot, the TV will be dead (standby) after a few tens of minutes ago. Exception if the casing is not installed / closed, tv can continue to survive long.
His conclusion, there is clearly a component of results weak.based try and error I finally get the answer to solve this case.
The solution is: replace STR 6754 and TR HOR.OUT (TT2140). Both of these components is very very hot temperatures, especially out his hor TR.
To avoid repeated complaints, sy replace tr: with BU2508F TT2140 following this by giving him a larger heatsink, with the purpose of heat dissipation in these components can be guaranteed.
Hopefully useful for you.

Sharp TV Troubleshotting

This tutorial discusses how to deal with issues / problems on Sharp TV (Silver Boxes series) more quickly and save time.
Jump at the core of the discussion:
Every time you get to the reparation. First sharp tv you have to clean it first with a brush or brush mainboardnya truncated approximately 2cm, to see and ensure there is no good who soldered joints, because the point of loosened solder who will be moved and you can see it clearly. Use high gloss paint thinner liquid (good quality and quick-drying) to clean dirty or stain on the mainboard.
Once clean, check all the solder points on the parts: supply-Flyback.blok Vertikal-Regulator/power this is the most often occurs because of heat damage to the solder point that ditimbulkannya.terutama solderan check in the feet and the vertical IC resistornya. care in the process workmanship, because this part is sensitive, even if you turn off the power was still remaining voltage on the vertical suplly elco (C: 470uf/63v).
Replace the IC if you believe the vertical or also damaged in the resistors marked with the changing colors vertikal.kerjakan carefully.
Try to turn on the TV and watch, if you still do not want to start normally, follow these steps:

If the flame-red LED to the green and stop being yellow, the damage occurred in the IC memory (24c04-24c16), replace it with baru.Setting who returned parameters used in the service menu.
If the red LED continues to die, the damage occurred on the main IC (TDA 938psxxx) or loss of voltage on the regulator 3.3volt, check the power supply.
If the green or red blinking, there is an error in the memory IC (internal error), you can reset it or replace it reset IC (IC reset the memory sharp tips will be displayed in a special tutorial).
If the LED is green for 50-10 seconds and back in red, there is a failure on the horizontal section, check the flyback (remove the scale and measure with a multimeter 10k on foot toward the ground and the leg TR.output horizontal collector, if it moves even a little means have short flyback . Also check the voltage of 180V to block the RGB, is common damage to the resistors of its boundary.
If the LED is not lit at all, check that the input power supply, check 6553/6554.ganti STR if they are damaged and do not forget to check the resistor boundary (6.8/10watt).
At the turn of 6553/54 IC STR check all diodes are mainly two diodes fruit corners, replacing them with the horse's mouth, if not STR certainly be damaged again, and this often terjadi.Bila you do not get the same diode bertype who, taking two diodes IN4007 connected in series and installed to replace every single fruit such diodes.
Conclusion:

SHARP TV series that uses the main IC TDA 938PSxxx, general and frequent damage to: SOLDE THE LESS GOOD, THE VERTICAL IC, MEMORY IC, flyback and regulators.

damage to the IC memory is varied, because there are damaged and some are because error.Pada cases caused by error or corrupted, can we overcome by logging into the service menu.
In other cases, for the Sharp series of black box that use your main IC TDA 8361/8362. broken standby often occurs on the 9V regulator, replace the IC 7809 and its twin capacitors and two resistors (18 ohm). Check whether elco 100-220uF/160Volt- IC broken .Check vertical and horizontal TR and fix all the points solder.and tips for this type if there is protectionism or tv do not want to start and only on the position of the middle leg standby.Remove the solder on reset IC is IC KIA 7045 program (disconnect the ground path her). IC serves to give the voltage on pin reset 5volt in IC program (on type SHARP 51R500) NICAM / IGR this part number: IC1003 (KIA7405).

Sharp TV qbeat type MK II with protek

20R200 Sharp qbeat jenis MK II, dengan kerusakan PROTEK. Mereka bilang kerusakan disebabkan listrik tiba-tiba akan mati. setelah listriknya nyala Tv nya tidak bisa nyala lagi (nyala sesaat dan kemudian lampu berkedip).

Karena kebetulan itu saya pernah mengalami kasus seperti itu, aku yakin dengan kerusakan langsung ke eepromnya. setelah saya buka tv, lalu aku menyalakan casing tv dengan tidak melupakan dua kawat jamperan dekat ic program saya sambungkan untuk masuk ke menu layanan.

Setelah itu saya isikan pengaturan menu seperti parameter di bawah ini:

Sharp TV 25 "with dark damage

 The TV is a Sharp 25 "with dark damage but the picture also looks discolored. Want to know How to Service TV Sharp 25" Black Images fade?

First of all I do is to disassemble the casing TV Sharp 25 "is. And then I immediately try to turn the screen on the flyback. Screen Manage this function is to monitor light from the darkness of the flyback. But after I try to play, Sharp TV picture" of this 25-inch tetep have not changed it was still dark and discolored.

Finally, I suspected flybacknya which leads to damage in the flyback this screennya. I've lost the original cables from the flyback screen and then I try to create their own path of the pin screen Colektor Flyback (these pins connect with the Horizontal Transistor Colector. The circuit is monitored and used to plug my work properly. Fig circuit enhancements as below:


I love VR 2MOhm intentionally to get the right light. After I connect the circuit and I try turns out the picture was still dark. Finally, I try to play his VR 2MOhm to get a screen with a higher voltage, I turn slowly and turned the TV Sharp 25 "This picture was suddenly bright and there are oblique lines to suggest that setting the screen is too bright. Finally, I try return the original screen from the flyback into the jar and TV Sharp 25 "it's my turn. and it works with a normal flame.

Why is this so? It turned out that this TV has a short tube which is between the screen with the Brightness G1 G2, and when I play this 2MOhm VR, which means I give a high voltage to the G2 Screen tubes and high voltage is what to release / free up short (konslet) between G2 and G1 this.
