Sharp tv 70DS-03SN, hiccuping PSU

[torbjorn]

A tv as above has hiccuping power supply. For each pulse, there is a flashover across R820 (1K0 SMD resistor, probably in beam current limiting circuitry). R613 (2K2 1W resistor in S-correction network at horizontal deflection coils) has signs of overheating and has changed value to about 12 kohm. All semiconductors in horizontal output seem to be ok.

Any ideas?

Thanks,
just like what i suspected. A good argument not to repair that set!
