| Sony | KV35V36 AA-2 | Shut down | KV35V36 serial 9024090 Unit has an intermittent shut down that only occurs after two or three days. When shut down occurs, the LED in front is Blinking and raster disappears but sound is OK. When flexing, heating, or freezing the main circuit board the problem can never be recreated. | Tech needs to order the CRT. Since we are not able to confirm any trouble with chassis The CRT is nearly out of Warranty. It is recommended that since we are unable to determine any chassis fault the problem must be due to CRT arc over. Note after 4 weeks of normal operation the CRT seems to have corrected the symptom. | Muller |
| Sony | KV35V36 AA-2 | PIP | KV35V36 Unit has no control over PIP channels. The PIP only displays the main channel. It will not change on its own | I asked the tech go through the ID codes for this unit and see if they were the correct value. ID3was 10 ID5 was143 & ID6was 0. These were wrong. The ID codes are supposed to be from ID0 ~ ID7 = 25, 55, 47, 10, 155, 6, 0. After resetting the ID codes the set operated the PIP correctly but still needed to set the PIP chroma phase | Muller |
| Sony | KV35V36 AA-2 | horizontal | Unit has a insufficient horizontal sweep. The sweep is reduced by 10 to 15% on the left side and 2 ~ 5% on the right. | When going into the tech set up parameters and adjusting the HSIZ value the sweep will change to full sweep. Monitoring the voltage at the Collector of @Q512 the voltage will vary from 27 volts HSIZ set to 22. When HSIZ is set to 48 Q512(C) will drop to 16 volts. The set will have full sweep but it has a slight foldover condition on the right side of picture. It is recommended the tech replace the retrace capacitors C511, & C513 and the Yokes"" capacitors C518, & "" | Muller |
