SAMSUNG ZOOM TOTALY DEAD

This time really make perforated bag (not a word Rano Karno, hehehe). Samsung zoom vision CS1439Z, owned mas Nardi, Sapen, Manisrenggo. Under these conditions the total dead, in a voice quite loud ringing on the SMPS power supply.
Tv is using IC MCU SZM-139, IC Chroma (1CHIP) m52777SP

After opening the lid back, check-type TR HOT SD1771 in a state short, I immediately replace with new. Tried ringing sound now turn away, ....... indicator light is a flame. At the start there are changes to the LEDs, but no any reaction on the screen and sound, what's this?

Check voltage on the basis of TR HOT absent. Note: if I use led to know it, mounted on base with ground, the position of TR HOT removed. All TR the drivers before the normal transformer, the other components around the IC Chroma (1CHIP) jg not find any discrepancy. Finally i try to replace the IC m52777sp and can turn on the ignition, turn off ... try to hold the heat sink gets very hot TR Horizontal teryata not normal, its allegedly defective FBT nih. Try to replace the former but ok FBT type FCK14A033.

Try again ........ can flame but why there are no broadcasts that stuck, try changing the voltage to normal tuner tuner type TELE 1-002A. Ooo ...... means that it is true tunernya damaged.
But why not focus the image, try cleaning the inside of the socket CRTnya (focus). Images can focus again. Alhamdulillah finally finished as well. In total it cost so much, but who have not said anything, because TV is giving parents.
good luck...

TCL TV 21276S Shakes IMAGES

This time can servisan TCL brand TV 21276S models of mas Rubiman manisrenggo klaten, with damage to the image getar2. Tv is usually used to view games from the PS2.

After being given an explanation of which had, I began to open the casing and cleaned, re solder in all parts of the eye observations found 2 electrolit capacitor is bald.
Replace both electrolit capacitor, 1 in 1000uF/25V c308 in vertical bag, one more elco 33uF/50V in Primary switching power supply. time to try ....... and cratttt images appear without shakes but why is accompanied flash, Oh no ... really turn out this way ....

the cause are so prickly is 33uF elco that I'd replace the power supply, after changing back to normal tv to a flame without the vibration and flash, alhamdulillah ........

Info from friend possibility that electrolit capacitor high ESRnya value is not suitable for switching power supply. Too bad, I haven't the tools to measure the ESR value ...
so good luck ...

TCL TV model 1497AT TOTALY DEAD

again TCL 14 inch TV, owned by Ms. Sipon, kecemen, manisrenggo.

With a total dead damage.

This tv set uses M87160m8-063FP IC, and IC M61266 chroma.

After opening the lid behind him, found a blown fuse / burning, of course there is a short / konslet this .... In my mind. When I measure the kaki2 elco 220uF/400v found large deviation results of multi-needle stuck position X1.

It found the regulator transistor in the short condition, I check typenya C5855?? which is a type horizontal TR. Why be installed there?

So specially for BEGINNERS to note the difference between type TR to TR-type regulator and to the horizontal, where to tr Horizontal no additional resistors and diodes Dumper. note the following images: examples of type D2499:

SONY TV KV-G21P21S TOTALY DEAD

Harsono father owned Manisrenggo Barukan village. With a total dead damage, accompanied by sound ciiitt ... ciit ... ciit from SMPS CIRCUIT.
According to a story that has, previously had diservice 2x, the first one only lasted 3 days, the second lasted 1 week.
This set using program ic type TDA 8375A.
Once opened, try to escape the burden of B +110 volts. Sound like ciit ciit ... .. is gone and the voltage power supply back to normal. Horizontal TR checked found in a state short. Replace with type D1877. Apparently this causes more strain on the power supply.
Do not forget to change also elco on B +110 V ie C 100uF/160V, and C 33uF/160V, for TR Horizontal durable.Also some elco kecil2 100uF/25V/35V (forget to note the location because it was night) on the voltage of 16V and 24v bare plastic labels.

When tested Cling ... the picture is still OK even though this tv has more than 5 years old.
Praise is one of this month ok ........
Thank you

SHARP TV Q -BEAT 20R200 PROTEK

Headache .... that's what I experienced when a family has a television service mbak ARI. because it was a few weeks has not been finished as well. so embarrassed that have the same.

Oya .. Tv program uses IC IX3098, chroma IC TDA 8361.saat would start a flame but 15-20 minutes later directly klaap ... klaap ... Peet back protectionism, the indicator light blink red.
check vertical IC broiling, I try to change elco2 around, still no change. replace the vertical IC, remains the same.
try to replace the flyback, remains the same.
TR and diode check all OK.

inconsequential steps ... to replace all the power supply elco wuiiih .... still no change.
With the help of a colleague of mine, finally subdued also the tv, teryata are so prickly all this is crystal blue writing on bodynya 503, which is located near ic Chroma. litle thing big influence ...
alhamdulillah finally finished .... also a relief.
Hopefully helpful, go ahead ....

STRESS PROBLEM KOP CRT ANODA

When making a television repair often we find damage in the form of leakage voltage on the anode tube headers. Marked with visible / faint of electric flame out of the rubber boundary header. This is possible because at this point there is a high voltage of 25 Kv.

The cause is often due to conditions that have changed the header of rubber elasticity, damage to the conductor plate in dalamya, also because of the erosion of the insulator layer is usually colored red on the surface of the glass tube around the anode.

Damage such as this if left for long periods can cause damage to the possibility of spreading to other parts on the TV board.

From various experiments in the field encountered ide2 to overcome this problem, there are disposable paslin, glue castol, replace with a layer of paint pilox, etc.. But sometimes not been able to overcome completely.

In our experience the necessary corrective measures include:

1. Replace rubber tube anode header plate along with it.
2. then clean the "red area" around the head position, with a cloth dampened with paint thinner A/ND quick-drying.

When the red layer is still there and it is difficult not need to be cleaned, , because later will be united also with a new layer.

Do not forget to also clean the anode plate hole.

3. Prepare paint "Enamel" (useful as a base layer before the paint on iron surface) with a viscosity sufficient, need not be too thin (Only if too thick add thinners ND). This material is used to coat re-surface around the anode tube is red. Can be applied with a small brush or the tip of a rather large screwdriver min. Layer eventually may be a bit thick but not apa2.
4. Wait until dry , rather long can until one day one night.
   
5. Replace the header, and ready tested. Hopefully helpful

Thank you

Samsung Unique die voltage B + ride

Samsung tv model CW-50836V in dead condition. Little white light on the screen, accompanied by a loud noise in flybacknya, and no leaks at the header of the anode.

From checking known defective flyback contained fine cracks on bodynya, so the voltage is snatched out towards elco nearby. Well ... can creep arround. Quickly turned off the set.

After I replace with a new flyback, and I re-coated on the glass anode with the location header of enamel. I try to switch it on, picture and sound normal.

die position, try holding body flyback and TR Hor kok exceed rate pretty hot. B + voltage was 135 volts. try change SMPS primary polarity capacitor, and I adjusted trimpot governing.

For BEGINNERS to consider if you want to play the VR adjustment SMPS power supply should position the set is OFF, the main power switch OFF, or pull the plug if necessary.

This is to avoid damage from pounding stress. Potensio likened volume may not be smooth, sound can come out GROKK grok ... .. something like that.

After the tv in the trial closed position for several hours. Otherwise OK.

Finally paid again .. hehehe.

Hopefully helpfull
