SOURCE: need resistor value for RK62 on DP2X board for 57SWX20B

RK62 is a 2.2ohm 1 watt metal oxide resistor hitachi part number 0700054M any 2.2ohm 1 watt resistor will work although it does have to be metal oxide(flame resistant) for safety purposes.

SOURCE: burnt out resistor near coils on bestec

First of all, it is very unlikely that a resistor "burns out" for being defective itself. Usually they are designed to run around 50% of their rated wattag. So they can get hot to the touch but are not over stressed. Therefore, it is more likely that you have something else that caused excessive current to go thru he resistor. So the point is that you can replace the resistor and more than likely it will fail again. You should start with a schematice of the circuit and look for components that could fail in a shorted condition and therefore cause excessive current to go thru the resistor. A schematic will tell you the value of the resistor. I am guessing that it is on a PC board and is therefore "surface mount" style. Look for defects in the board trace causing shorts. A good place to start. Hope you find it. Lots of Luck.

Panasonic tc-21v50p, anybody knows the value of resistor located @ regulated power supply r833 its burn cannot read the value. It is also have resistor parallel connected to this resistor


If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Circuit diagrams to many popular brand TV SMPS are given. You can figure it out there.

Short internal power supply


please check for any blown fuses, if there is replace with the same value, do not replace it with a higher value. also check resistors near the rectifier diodes, check full wave diodes & ic regulators, if you find an error replace with the same value or specs.

Error Code 2-2. (Low Voltage Supply) What now?


That is a power supply issue and this requires a skilled person to do it.Trouble shooting in this kind of problem includes voltage measurement and resistance reading of the components/parts inside the high voltage section This is not a DIY problem but if you still want to do it yourself then I can give you some guide that you can try.
1.Check the power supply board,this board is where the power cord is connected.The common problem on this circuit are the filter capacitors .A leak and shorted capacitors always cause that kind of problem the worse is dead set.To visually identify a defective capacitor is their appearance they look to be bulging on top blown,theirs a liquid leak on the body.replace the defective capacitor if you found any.with the same rating and value..
2.Resistors -change value resistors and open resistance can cause the same problem this resistors usually near the regulator transistor.They appears as burned and overheated replace it with the same rating there is an available color code calculator of resistor in the internet click this link and key in the color of the resistor to get the value..

3. check the voltage regulator transistor if it is shorted .the first pin and second pin must not have a reverse reading..

4.Check also the two big IC marked with STK xxxx this IC are the convergence IC it controls the horizontal pin of picture..when this IC are defective this will shut down the power supply ..

The steps I mentioned must be done with a skilled personnel If you feel you can do it,well you can try or better yet bring it to the service center or call a service technician...click this link for service center
good luck hope this helps!

I need the value of resistor connected in the Ac line, what value is it?


Hello
Your post is not clear. It doesn't specify tthe brand name and model number of the TV. Anyway I hopes that you are in need of the value of series resistor [ a wirewound one usually cement type] I thinks and post this solution.
The value usually will be between 3.3Ohms to 4.7Ohms [ 7W] wirewound type resistor.
If this resistor has opened, look into its power regulator side for any defects, before replacing it with an other one.
OK.

Black Screen One resistor is found Blown inside BWB but value unknown ! Please help !


Depending on the resistor, the values for a resistor is color coded, meaning that there are a couple of lines of colors and each color line represents a value. Do a google on Resistor coloring chart and you might find your answer. If the resistor is a surface mount one and very tiny, you might be out of luck as these are too small for the manufacturer to print the part number on. Only the manufacturer has that part number and can be very hard for you to contact them about.

Power supply not switching


replace the regulators,check for change value resistors at the power supply section or resistors near the regulator.check for shorted diode and leak capacitors..also check the horizontal output v transistor..
