I immediately replace these resistors with 2 pieces ohm/1watt value of 1, do not forget who I replace elco 22/250V my guess is the source of the burning of the resistor divider.When you get crystal TVs 29 "amazon with damage like this, you simply replace the R2046 and R2047 (1ohm/1W) and C2012 (22/250V) and C2018 (47/16V) ... done.In the case of crystal tv the other one is narrowing / smaller horizontal width on the left and right with the image / raster do a bit warped.Such damage is clearly due to the voltage output is not hor stabil.ini elco components caused by C441 (100/160V), which has been leaking and bulging.Easy and simple, may be useful ......
