I received a non-working RCA F31317 tv (chassis CTC203CA5) and after looking inside I found a burnt out resistor in the PSU.
The part number is R14109. I need to know the value of the resistor so I can replace it. It appears to be a light blue resistor
and the first color ring is yellow. After that I cannot tell the value. Please let me know anybody if you know the value. Thanks.

Re: Need value for part R14109
R14109=750ohms 5% 1/4w
There is much more likely wrong with the TV. Resistor don't normally burn out with help, say, without a failing flyback transformer and possibly taking a transistor or two with it.
If you need the manual, go to
and type in "F31317" into the search field, you will several listings.
If you decide to replace it yourself, here's some more part numbers in case you need them.
Necessary parts: Transistor(Q14401)
Main Voltage regulator Q14101
Resistor R14109 open.
Research indicated the flyback transformer most probably bad
Hope this helps you.

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.

just follow the power cord where it goes into the tv and there is a small glass fuse right there,check to see if the small wire inside it is burnt out or if the fuse appears to be white or black inside.
the front panel assembly is rca part # 237420
I assume your chassis is a CTC203
Un plug the fpa and see if problem still acts up
you may not be able to find one
then try replacing the sticking buttons on it
this symptom is characterised by the loss of one or two primary colours. this symptom can be classified into three cases: 1) loss of red colour, 2) loss of colour blue,3) loss of green color. this symptom may be caused by a trouble in the colour demodulator, in the color amplifier or in the colour subtraction amplifier circuit. in your case loss of blue colour. this is a very complicated problem that you need some special test equipment like oscilloscope and color pattern generator in order to trace the signal. tune the receiver to a color broadcast station(a colour bar generator can be used to transmit a colour signal to the set). check the Z-axis demodulator, z-axis amplifier and the B-Y output circuit for the chroma signal. observe the signal process with an oscilloscope. if the color signal is not present use a VOM to locate the defective component in any of the above circuits. check the transistors and the resistors in the collector circuit. good luck!
Check for an open R15103 on the CRT drive board. It may have been one of those discolored ones you noticed. I think it is a 10,000 ohm 2 watt resistor. You may want to replace R15101 and R15102 at the same time to prevent those from going out as well if the 15103 resistor measures open after you remove it from the neck board.
