RCA 32V550T Power On Problems/Question
I just got a new RCA 32V550T from Circuit City. I'm a little worried
something might be wrong with it. Each time I turn it on, it takes a full 6 seconds before the picture comes up. I can hear the TV power up as soon as I press the power button, but there's no picture for 6 seconds. Is this normal for this model? Thanks! |

This is normal. The uPC has to boot up. Your set is run on a lot of
internal software that has to load from an EPROM. -- Greetings, Jerry Greenberg GLG Technologies GLG ========================================= WebPage http://www.zoom-one.com Electronics http://www.zoom-one.com/electron.htm ========================================= wrote in message om...

Your set is run on a lot of internal software that has to load from an EPROM. -- Greetings, Jerry Greenberg GLG Technologies GLG Been reading into training "white papers" on various chassis found in RCA TV. Micro doesn't boot up during turning on that set. Micro starts running, loads data stuff, and do several system checks then settles down waiting (looping) for a power command from front button or remote after set initially plugged in. Once command is given, micro sends out commands to other sections turning relay, putting out pulses etc right away, what takes awhile is tube heaters takes time to warm up till AKB set trip point lets picture comes up. Note that there is bulletin for this ITC008 chassis, not just this model. Just worked on one last week in other problem area but found this bulletin while checking the partfinder II on delayed start up, it involves a change of a part in SMPS. Secondly, 6 seconds is just long for a automatic cathode bias adjustment so has to get set checked at rca warrantry servicer authorized and see if bulletin is done on that set. Oh, there is another note from thomson on ITC008, there is batch of bad fuses in those, we had a service call last friday at customer's place, new fuse fixed it up. I'm glad there is newer chassis with out gemstars for once (ITC008). :-) Cheers, Wizard |
