PFL Posted October 10, 2012 Share Posted October 10, 2012 I just got a light sixer this morning. It has a problem though. When I switch it on with no joystick plugged in the picture is crystal clear. However, when a joystick is plugged in there is interference on the screen (kind of like when a hair dryer is on). Of course, I've switched the system off when plugging or unplugging the joystick. I've also tried different sticks, a different PSU and a different coax lead. It's a PAL CX2600 U and I'm in the UK so it's not a channel switch issue. Any ideas?

yllawwally Posted October 10, 2012 Share Posted October 10, 2012 I would say it's probably the 7805 or the chicklet capacitors They both are cheap, and pretty easy to replace if you're handy with a soldering iron. The caps are little green things that look like chicklets, and I think they are .22uf 100v. The 7805 is right next to the power connector. It a black square with three legs.

PFL Posted October 10, 2012 Author Share Posted October 10, 2012 Thanks for your help. Are these what I'm looking for? 7805: http://rover.ebay.com/rover/1/711-53200-19255-0/1?ff3=4&pub=5574883395&toolid=10001&campid=5336500554&customid=&mpre=http%3A%2F%2Fwww.ebay.co.uk%2Fitm%2FV-REG-5-0V-TO-220-3-340-NATIONAL-SEMICONDUCTOR-LM340T-5-0-%2F390456135926%3Fpt%3DUK_BOI_Electrical_Components_Supplies_ET%26hash%3Ditem5ae8ffd0f6%23ht_702wt_1140 Capacitors: http://rover.ebay.com/rover/1/711-53200-19255-0/1?ff3=4&pub=5574883395&toolid=10001&campid=5336500554&customid=&mpre=http%3A%2F%2Fwww.ebay.co.uk%2Fitm%2FMetallised-Polyester-Capacitor-100V-0-22uF-10-Pack-%2F300782704231%3Fpt%3DUK_BOI_Electrical_Components_Supplies_ET%26hash%3Ditem46080bd667%23ht_1699wt_907 Quote Link to comment Share on other sites More sharing options...

yllawwally Posted October 10, 2012 Share Posted October 10, 2012 The capacitors aren't polarized so it doesn't matter which leg goes in which whole, when replacing. However when you replace the 7805 make sure it faces the same direction as the original one. Quote Link to comment Share on other sites More sharing options...
PFL Posted October 10, 2012 Author Share Posted October 10, 2012 Cool. Thanks guys. Just one more question though. What's most likely to be at fault here? The caps look a little awkward to get into so I'm kind of hoping that just replacing the 7805 will rectify (see what I did there?) the problem. Of course, I'd do the caps too if I have too but I'd rather try one thing at a time. Quote Link to comment Share on other sites More sharing options...
mtshark7 Posted October 10, 2012 Share Posted October 10, 2012 I'd replace the 7805 voltage regulator first. Quote Link to comment Share on other sites More sharing options...

PFL Posted October 23, 2012 Author Share Posted October 23, 2012 Just thought I'd let you guys know that I've replaced the 7805 and all seems to be well now. I'm very happy as now I have my woody in the living room and my jr in the bedroom. VCS heaven! Thanks guys for your help. Quote Link to comment Share on other sites More sharing options...
