Pulling out a pipe breakdown short circuit. Do with 40 w bulb load, quantity B + 52 v, jumped to 75 v, protection, dropped to 0, again immediately. Amount of power supply is normal, just to protect the CPU OFF the foot protection signal sent out, supply TDA9116, KA2142 12 v disappear, then hear the degaussing relay phenomenon is OFF.

Disconnect the booster pipes G, boot, complete protection. It is surprised, think about whether there are other places have short circuit protection. Or high pressure didn't establish, machine to protect themselves. And check off the line, the tail board found no apparent short circuit. But ascending tube first. Sdiservice manual download site

She was SC5802, don't have to find the original SC5521Z change, boot, protect disappear. B + about 58, power supply is normal, Sdiservice manual download site
She had, even on the host, the image is normal, but the field frequency to brush up on: Sdiservice manual download site

If the line is S a is capacitance circuit has a problem, why in 1024 * 768/75/60 k can be normal? Don't understand. Sdiservice manual download site
S correction circuit is S1-3 control access capacitance, I checked the S correction circuit switching table: Sdiservice manual download site

In 53, and 68 segments to brush up on, of which 68 section of the three S correction capacitor didn't access, can be fixed C431S correction capacitor has a problem? Take down complete failure, in the new, with electricity in 1024 * 768, 68. 5 k, 85 has been normal. In 53 S2 access abnormal capacitance also has a problem? To remove a little amount of capacity. After the change completely normal. She slight fever.
