I have a 2005 RCA 52" HD projection television which doesn't work. I took off the back panel and looked at what appears to be burnt resistors. I have a Thomson ITC222 Service Manual and the numbers above the resistors are RL040 and RL043. Below the RL040 is "1K5" and below RL043 is "47R0"

How do I find out what type of resistors I need to replace? One has a gold ban on it. The other is burnt too bad to determine the colors as well as the rest of the colors on the other one. The board in which the resistors sat is called a PSD board; perhaps meaning power supply board. I noted that RL would stand for resistor and horizontal. I do not know what the component numbers (043, 040) stand for nor the other numbers/letters below those numbers.

Finally, the most important question: what causes those resistors to burn out? Power overload? Should I check fuses? I am a neophyte in this area of repair and would greatly appreciate any help anyone could provide. Thank You.

If the golden ban is on the resistor marked 1K5 then it means that it is 1000 ohm resistor with a tolerance of 5%. The second resistor might be a 47 ohm resistor but I’m not sure. And yes, it’s the power overload that causes these resistors to burn out. It might not be a fault of fuses in some cases, it can also happen because of bad power supply circuitry or prolonged use of a device.
