Re: bush ws7680 tv pcb
Yes it can be replaced if you know the value in ohms and watts and you can use a soldering iron. Resistors normally blow because of excessive current flow sometimes caused by downstream or upstream components that have shorted out or are being overloaded beyond what they are rated at. Sometimes (but rarely) they just blow for no reason.

Open the back cover of the monitor.. check the fuse at the power supply board... If the fuse is open, replace with same value.. at the power supply board check for any blown capacitor and replace it with same value. Check also the power cord for open connection.
It probably has blown a fuse, and you will be fortunate if that's all the damage.
The EHT circuits are very susceptible to breakdown if any moisture is present.
You must dry it out as soon as possible - half a day left wet is too much.
Use dry compressed air to thoroughly blown any moisture from the pcb and all other components.
pay particular attention to where moisture might be retained - such as under components mounted on the PCB.
All moisture must be removed, otherwise a combination of corrosion and electrolysis will cause electrical leakage between components and/or eat the pcb tracks and any other exposed copper.
Look for any obvious signs of carbon tracking damage.
After dry out, replace any blown fuses and try again.
If it has been left wet for some time (days) it will most likely be unrepairable.
it's very difficult to give the exact value of that resistor.,but i can give some tips to find the value of the said resistor .( find how the resistor works, it is a dropping or fusable? if fusable used .47 or 1 ohm resistor if it is a dropping resistor you should make a trial and error .from 100k,10k or 1k.
The red line on ICS is quite normal it does not mean the part has failed.
To be honest in most cases if a tv has been hit by strike it is a right off & scapped.
What I suggest is to remove the main pcb & power supply pcb if its seperate & inspect the print side of pcb for signs of arcing tracking or burnt track. Repair any damaged track by cleaning off the coating to get at clean copper then solder wire accros to bridge the damage.
Check the power supply resistors diodes transistors look carefully for any burnt components or components which are physicaly damaged.
Check the line output transistor this will be near the large transformer with a thick red ht lead going up to the crt.
Check all the components you can in the line stage look at all the ICS to ensure none of them have holes in them or have blown apart.
Hopefully you find some or one if your very lucky that is damaged replace it & try your tv.
No it doesn't sound like a resistor, it sounds like you have a short in power supply, you can look for bad Diodes in bridge rectifier,or solder bridge, or transistor short, start from beginning to end. It is definately a short and most of the time resistors open and this will not cause a blow just a dead set.
First, first C613 means that it is a capacitor, not a resistor.And It seems to be a electrolytic Capacitor.If it has burst, then it's can will be inside. just search. the details of the Capacitor will be on it. most likely it will be a 10mfd 160V capacitor. Check and replace.
