The resistor on the top left of the circuit board is bad. It has a 4-band code but it got hot enough that some of the colors are difficult to be sure of.
A lot of these digital timers have same problem with the L1 and L2 resistor... but careful inspection usually reveals that several other parts also have blackened solder connections, indicating that the entire circuit board is burned.

Often people ask for a schematic or for method to identify the resistor, but I have not found any resource from any of the manufacturers.

yes those two resistors are also 3.9ohm 2watt 5% resistors

The resistor you see is a 2.2 ohm 2 watt resistor and is part of the convergence circuitry. I would replace R7011. 7012, 7013, 7014, 7015 & 7016 (all the same value) and the 2 STK392-110 Convergence ICs. This should fix your problem. You can find kits on-line for around $45 with the IC's and resistors together.

Your model doesnt have convergence ICs. You can get the replacement parts and free instructions on how to do the repair at the following link, just click on the contact us link on the lower left hand side of the website and tell them the model number and chassis they respond quickly.

It's recommended to replace all the defective parts first because if you only replace the defective resistor, it might burnt again if the convergence IC is shorted internally. I would also suggest to measure the other low value resistors with multimeter.
Testimonial: "Thanks! I'll just replace everything. I was leaning on starting new anyway. Thanks for the fast response!"
There are two types ofsurface mount resistors used in an electronic circuit board-the 3-digit and4-digit code SMD. The first two digits represent the two digits in the answer.The third digit represents the number of zero's you must place after the twodigits.
Theanswer will be in Ohms. For example: 104 which mean 10 0000 (4 zero's)and the final answer is 100k. Let's calculate the 4 digit SMD, 1182 which mean118 00 (2 zero's) and the final answer is 11.8k.144 views
