You can get the 3.9 1/2 watt fusible here but they have a 10.00 minimum order to qualify for free shipping so you may want to leave them a email if your order doesnt total 10.00

I have a 46inch samsung tv model number UN46EH5300FXZC, i have sound but no picture can see slightly with the flashlight test, no backlights, i can't find many parts for this tv wondering if it has...

Capacitors can look fine but capacity measure is real and only good to do to measure with a no-lie capacity meter minimal like this kind of capacity meters. not only bulged convex topped capacitors to find in Samsung even the 2 and 3 watt green colored resistors can have faltering end caps on some of the resistors thats not to see but only on thermal failure or manipulate with a wooden object beginning out of the power supply loose cold solderings on the supression beats coils in the backlight inverter are for years a common problem where the wires are made not good free from insulation lac on outside soldering end on the wire are faltering and can be loose a little manipulating on coils and the 2 or 3 w resistors beware by manipulating it can give back an ccfl start even if the endcaps can be loose that are faltering much more other brands have had that same problems with the same kind of coils (not the step up transformers )seldom that step up transformers themselves are the problem whether smd components in Samsung are not so common as LG televisions with a much more complex repair problems then Samsung , but capacitors are no longer generally havelifetime in Samsung devices than 6 years at the most but are often rather common and not always that they are leaking to be Taiwan and Korean capacitors have factory brands and have even a too tight tolerance choosen tjhe max power , if replace choose capacitors at least 10 / 15 volts higher on the same capacity if replace , if the body format size will in most case be the same to mount between other components and look for service manual for measurement control the power supply first all of the fuseable resistors to find before find cold solderings or leaking bulged or deformed capacitors the fuseable resistors are vertical mounted resistors or some higher mount on the print placed resistors in most case on a lower resistance to find almost always that are 1 or 2 ohm resistors.
Beware Backlight inverters are having high voltage to the ccfl tubes if some capacitors are to low on capacity to find measure on difference between the upper and bottom step-up transformer coils is very likely to do if a capacitor is no longer have a self-restoring the range of the backlight power can become too high and the transformer on one side upper or bottom can be blow up. and then there is an protection too find when the upper tube rail and bottom rail are pull a little out the topside and bottomside of the screen a pull a little out if you start the television in a little time you see a short flash then the backlight inverter is having a similar problem it goes in protection.
Best if one transformer is defect go for a refurbished print and if a new backlight inverter is neccesary and will prevent for new time of 4 years the same problem replace capacitors by Nichicon Rubycon Elna frako Nippon Chemicon or even Jamicon or brands with a good long lasting dielectricum more then 10 / 15 volts higher choosen, all the marketing technical choices by brands are choices to have an existence, its free to choose also for a new backlight inverter if repairs or have no experience in soldering .

My 25LTD CB has been tuned and peaked. I just replaced the meter and it spikes hard when keyed. How can I adjust it without degrading the tune?

It could be the variable resistor that sets the meter movement or it could be the person that tuuned and peaked it didn't know what they were doing and set a high dead key. The radio should key low and then swing high. You must first track down which one is the problem. You will need a good watt meter for that. If it isn't a problem with too high a dead key then go to CBtricks and look up your model of radio and find the "VR" variable resistor that sets the meter. Open up the radio and turn the resistor to match the meter scale with what the watt meter reads.

Hi both cars operate from same controller ???

Yes but it needs to be the SAME Hmz For e.g. 27 Hmz and 27 Hmz will work BUT if so its 24.98 hmz and 24.00 (same as 24 Hmz) Hmz will not work that i dont know why.Depending on the cars speed(s) it will still go!

More problems no worrys!

I have a jl 1000/1 mono amp and my low ohm light was on and making a buzzing sound and found that there was a resistor that one of the terminals broke off and now no matter where i look i cant find the...

The 5 ohm could be challenging, what you could try is to get 2 10ohm 3 watt and put them in parallel. Will be 5 ohm and 10ohm is easy to get

Hope that helps

Amp repair advice

check on the board to see if there is a resistor that looks similar, 90% of amps amps are matched in there design, meaning the left side is usally a carbon copy of the right, so if you look at one side and there is a resistor that looks like it's in the same spot on the other side, good chance thats the same one, read the colors off the one thats not burnt up. resistors come in different wattages,1/8,1/4 1/2 up to 10 watts, each wattage is a different size, most of the ones you see in the amp are 1/4 watt but some are 1/2 and 1/8. some on the output are 2 to 5 watt, but those are generally 10-18 mm in length, they are big ones you cant miss those. so once you get the color code, read the colors, ex red,gree,brown,last line is either silver or gold, that will tell you the resitor value. then google resistor color codes and then you can match the color sequence with the value codes, and that will tell you the value you need in ohms but then you have to get the size 1/4 watt resistors are generally about 6 mm in legnth, im measuring the actual part of the resistor not including the metal leads, just the body, so if its larger its probally a 1/2 watt if smaller its an 1/8 watt, 1/8 watt are about 4 mm. now go buy the resistor, but you might find it that tough, if its a common value radio shack might have it, but resistors are so cheap, pennies for a handful, good luck on your search.

Samsung pcl5414r power resistors and pico fuses??

Hi again and welcome back to FixYa,

Appreciate the direct "Ask Me'.

Based on your original post, only the STK ICs were replaced. Presumably 392-040, the surrounding resistors and pico fuses could very well have been affected as well. Depending on the board revision (pls confirm location numbering on the actual board), the resistors could be:
RZ104 -RZ106 - 270 Ohm 1/2watt
RZ133-RZ135 - 27K Ohm 1/16 watt
RZ136 & RZ138 - 3.3K Ohm 1/8 watt
RZ146 and RZ147 - 3.9 Ohm 2 watt
RZ148 and RZ149 - 150 Ohm 2 watt
while the pico fuses would look like the image below.
Good luck and Thank you for using FixYa.

Samsung problems

If the fusible resistor is open, yes it could cause this problem. Check for others in the area as well. Is that resistor 3.9 Ohms?
I'm guesing yes. This is likely the current limiting resistor for the IC. There should be another for the other IC as well. Look for pico fuses in that area that may be open.

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.
