    can you add more before our replacement?? can you give more troubleshooting techniques?? only r68g resistor was burn after checking..



    we already tried to replace the component.



    thanx..

Hello my friend, if one of your power supply's part is burned, your power supply won't work else if its work i has a short time to operate and it will be burned the whole board of your supply. Mainly the reason of burning your supply are the following: 1. The Electric supply  from the source is to high or above the limitation of your Power supply. 2. Your power supply is over capacity. 3. You're power supply board develop a liquid moisture inside that is why it shorted and eventually the board is burned.  4. The load of your power supply is overload due to some device you attach that is beyond to the limit of your power supply's wattage capacity.
Note: try to see the wattage or voltage or the capacity of your power supply can supply the electricity within your computer system. To ensure that it does not exceed the limit of your power supply's limitation.  I therefore reccomend that to avoid burning the entire power supply board from short circuit, it is recommended to replace your power supply to avoid incidents may arise.
Hope this advice helps your problem. If you need more assistance just reply to this post.  If this solution or recommendation is able to solve or help your problem then please rate it.  Thanks

    try to used tester then you can check resistor, capacitor and other parts of the power supply board to ensure is still functioning. Also try to see and evaluate the source of your electricity. Then avoid to plug the power cord to your computer especially in to your power supply to the directly in the power source. try to use AVR or Automatic Voltage Regulator.
    thanks

Convergence Resistors keep burning up


Some simple advice---if resistors are smoking one of the chips is shorted----The set has two voltages that go to them--one a positive voltage and one a negative voltage.

If either chip is shorted you can replace the resistors all year and not get anything. The resistors are protection in case one or both chips short----

Remove all old heat grease and install two new chips and replace the resistors at the same time.

Note that the set may have pico fuses on the power board also.

Resistors burnt out & I cant make out the colour code as they are burnt black. how do I know what resistance they are so I can replace them?


Hello, resistors burnt out, why? If you replace the resistors will the new ones burn out? What you need is a diagram of the unit and you can get the resistance readings from that. But the question still remains, what caused the burn in the first place and have you repaired that?

I have an RCA RT2780 - receiver unit, and one of the resistors on the power supply board is burned so much that the color bands are not there anymore. The resistor is R202, if somebody has the circuit...


The resister called for is R202, which is a 1 Watt resistor and makes up a "snubber network" with C211, which must be replaced as it shorted, which caused R202 to burn out. This short will not show on any tester as the short only occurs above 25 KVAC from the spikes that this system typically produces. Do not replace C211 with same value capacitor, because it will also fail. The MFD rating must be the same to resonate with the frequency, but up the VAC rating. Engineers typically design these @ 12-25 KVAC and you need a rating of 35-50 KVAC, since the voltage spikes easily exceed 30 KVAC.

HI I have a FSP200-61GT SPI switching power supply with a burned out Mosfet on the high voltage side. There is a (I think)a .5 or 1 watt resistor on both sides of the mosfet. But they test good, my problem...


Please give motr of the devices fixed on same heat sink. Search for SMPS IC like FPS or similar, search their application notes and the datasheet of the nMOS. then you can get idea. without those data Solution is impossible.

if r 11 is bad you should really check the bearing on the tub you will probably find it to be bad or going bad causing the moter to pull more amps causing r 11 to burn out.

Magnavox 51MP392H/17


From my experience most people find out their Convergance IC's were the cause and burned out again because of faulty 6.8 ohm resistors or just plain failure to replace the the resistors when they replaced the IC's. sadly if your planning on spending more money I suggest New IC's use 150's instead of 120's ALSO, make very sure you've changed out all 12 resistors and make sure they are metal film resistors.

Great reference link that I posted pictures on, check out page 3
http://www.techlore.com/forum/thread/16736/Magnavox-51MP392H-17-51-quot--TV-has-double-vision/

Where I got my parts that worked:
Suburban Electronics
http://www.suburban-elect.com/
Manual Library you should find all you need here:
http://www.techlore.com/group/2/list_downloads



What you possibly need:
(2) STK392-120 OR STK392-150 IC
chips
(12) 6.8 Ohm Metal Film resistors
15 watt pencil solder pencil, DO NOT use a high watt iron you will fry the surface mounted item.
good leaded solder, and flux

BTW, if you give up on the TV I'm still looking for a Convergance circuit board yours sounds fried but I would mind trying it out its better then nothing, and ther are a few other people on here looking for parts... so you never know...

Power on but no led display


"Power board:
The power supply is the main culprit for most of the TA-E9000ES failures. Symptoms of this are no sound and a very dim or no display. Apparently the power board has several weaknesses which have caused Sony to supply a modified version in later production units. The circuit around transistors Q108 and Q109 are prone to oscillation, which will cause one or both transistors to break down, as well as resistor R124. This resistor is originally a surface mounted device capable of 1/10 watts of heat dissipation. The modification suggested by Sony is to replace this 4.7 k ohm resistor with a 1 watt rated version. Also, to prevent further oscillations a 100 pF capacitor is added in parallell with R153. (Some suggests that also transistor Q110 is a candidate for replacement.) The US issued service bulletin from Sony suggest that this fault may occur with units having a serial number in the range 800001 - 802746.
Serial numbers 80#### are for the US/Canadian version.
Serial numbers 50#### are for the european version."

Onkyo TX-DS595 with no display?


Ran my 595 blind for 2 years and finally spent the time to diagnose it this year. Turns out that one of the resistors that is on the power supply went bad. Similar problems have happened with later models so i thought the same may be true for the DS595.

My Receiver has always run fine.. just no display anymore.

Here's the fix. Replace R9501. its on the larger board that is part of the Power Supply. You will have to take the 4 large screws out of the base of the big heavy power supply block to find the resistor. I believe the old resistors is a 1/4 Watt. I replaced it with a 1 Watt so that it can handle the heat of being turned on and off better.

The resistor you will need to buy is 2.0 Ohm. I wouldn't go anything less than a 1/2 Watt and preferably 1 Watt.

My receiver works line new now!
