Str burned need to replace want now which no use in

If STR is found damaged, you should check all the assciated components with it; like resistors, zener diodes etc: before replacing a new STR. All such components should be checked individually [out from the circuit]. Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

Protect typically means that the fuse blew because something in your receiver went bad. It's now protecting your speakers from that badness. You need to get the receiver fixed or replaced.

First of all; it is DANGEROUS to fix a power supply if you don't know what you are doing. Thus; don't even think about to open power supply tower, if you are not qualified enough.

If you are a qualified person, you can go on with below steps by taking risk on your own.

You must discharge biggest capacitors in order to avoid any fatal electrical shock. Even it is disconnected from electricity plug, power supply may keep high voltage in it for long time. Once you discharge big capacitors; you may diassemble power supply tower. At your question you mentioned about burned power supply which makes it a little bit easier. (I assume you discharged big capacitors) Once you open psu tower; do visual inspection on each capacitor. If there is a burned area start with it. Remove blowed capacitors and replace them with same valued new capacitors. If you can't see the values on blowed capacitors; you need to find board diagram of your psu. Otherwise you can't find suitable one to replace. Besides; check form of other capacitors. If there is a change on any capacitor's form, replace them too. The best way to find out dead capacitors is using capacitor testers. If problem caused by another type item; its not easy to find it as finding bad capacitors.

There are internal fuses that you can check. This model was notoriously bad for amp problems. These amps would burn up a lot of components when they go out.

Check all the associated components at the power supply regulator section circuit; especially check the zener diode/s. Replace them. Replace the STR only after replacing these components. There is a chance to these components too can damage, when the original STR has burned out by any reason. If you wish to get more, about the schematic diagram; check the site linked here. Type in the number of STR in its search box, or Pull up previous posts, either by type in the Brand name to your set in its search box, or view it in Mosaic / Timeslide / Flipcard option. http://electronicshelponline.blogspot.com/

no burn.no output voltage on ic 050rdc2

Hello

Before replacing the STR, have you checked all the components related to it? When STR burns out some of the nearby components, such as zener diodes and other resistors will also get damaged. You just replace the components, especially, zener diodes, in case it does not show any fault, replace it. Connect a 100W filament type bulb in seris with the power supply, and switch on the set. This will reduce the power concumton at the begining, and we can check its heat effect also, after all are ok we can connect directly. Check the smoothing capacitor at the secondary 130VDC. Replace it also. If you need furthermore assistance, feel free to contact me through Fixya. I'm an Indian, residing at Trivandrum, the capital city of Kerala State.

Make and model of the TV will help us do the research.

i have monitor ,the problem is ,after 2,4 mint my mointor turn off,in the borad STR G6653 transistor burned out ,i alllredy change it but after one month they again burned, pleases guide me for the replacement of this transistor ,give some list of this transistor ,i want to to used another transistor in the behalf pf STRG6653 transistor
