Sony | KP53V15 AP | Dead | Unit is dead. Will not turn on. Just shuts down | Q811 shorted. Tech replaced the transistor with a 2SD188. Tech checked the distribution of high voltage for pin holes in the lead dress. Nothing was found. The transistor did not overheat and he let it run for 45 minutes. Suggest the set run for a while and see if it shorts again. All looks well in its operation. | Muller |
Sony | KP53V15 AP | CONVERGENCE | Unit has a pulsating red convergence . | Tracing the pulsating we find the output of IC506 has a pulsing on it that is coinciding to the pulsing on the screen. Unit has a defective IC506. | Muller |
