Question about RCA F36673ET 36" TV

Open Question

Dead fuse was blown, power resistor 2.7 ohm 15 watt was open, replaced both and the fuse blows again. The power supply seams strange to me. The 110 volts is rectified then it goes to a transformer? That seams backwards?

3 watts metal oxide resistor. Don't have to worry about volts. Just use a 3 watt

The tv wont light up


1) test the power supply , see the blown fuse or c.breaker tripped and reset.
2) Proof again, if the problem persist the problem arise with the power supply, some diode, capacitor, resistor, etc can be open or short. repair.test the power cord too, and main switch for open
3( see the diagram .God bless you

No power


Most likely that open 5.6 Ohm resistor is in the power supply, is it a fairly large squarish resistor? If so just replace it and try the set again. I think it's a ballast resistor that has opened up and this can happen with age especially if it was not perfect to begin with.

Try replacing it, I bet it will fix the problem...

I need to knoe witch fuse is the power protection relay so i can replace it.


It is the fuse closest to where the power cord goes to the main PCB. It is a glass fuse held in by 2 small clips. If the fuse is blown and you replace it only to see it blow again, you have a dead short somewhere in that power supply. Be carefull and remeber to unplug it from the wall. Don't need a shock. Thanks for using fixya. Hope this helps.

Fuse blows


You have a shorted rectifer diode,also ck fuse resistor its the big white one 2.7 ohms 7 to10 watts.and your hori outout transistor.

Fuse blown


ok well i would check for a open diode in the main ac to dc power supply then check all resistors that look lick they may be low ohms but high watt check to see if you might have a open pico fuse from primary power supply to the regulator check and see if you have stand by voltage this would be easily checked on the power off oan on button get back to me k

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.

Fuse blows when it gets plugged in


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.

Could it be in the HV circuit? first you isolate h/output section from power supply. make power supply output ok. check h/output section for short circuit 1 print short near eht 2 diodes or cap.near eht 3 yoke H winding just by removing connector 4 EHT transformer regards
