Hello: Try this, Turn key on, try to start, let k/switch come back to run, let set for 10min(security light out) turn key off 10sec, turnkey back on let set 10min, turn key off 10 sec, turn key on let set 10min. turn key off 10sec. turn key on start car if it doesn't start and the security light is flashing you have a passlock problem and it will require a new lock cylinder assembly and the above learn procedure.

When I start up my Samsung 52 it has a VERY long delay


Are you retarded? remote batteries? Sounds like your power supply is toast.

Tv takes 30 min to cut on... but when it does no picture shows.


LOL sounds like you just need a new TV buddy, there are multiple components that are going out, first start with the green lines or "pixelations" these are caused by the tv no longer being able to regulate the electricity in those pixles and are as a result 'Open'. The 10 minute things is more of a energy conversion thing and sound and video on and off are connection issues (internally) so take it to a repair shop but if the price to fix is greater than 1,000 you should be willing to scrap it for a replacement. who knows the shop might buy it off you for cheap...

Good Luck

This is my Fav...
pricey though but can keep an eye on ebay for half price divorces.. :D

Samsung lnt4042hx/xaa 40in lcd tv wont turn on


I concur with Lightnbaby.... had same problem... my TV LNT4042HX/XAA took 10 min to start sometimes... the capacitors on the power supply board had bubbles on top 4 of them all 10/1000Uf. Samsung wanted to charge $220+ to have a guy come out and fix. J&J parts (samsung vendor) wanted $108 for a new board. I replaced the 4 capacitors for $4.68 and the TV works fine now!!!!!
