Toshiba 27" TV not starting correctly

Hello,
I am working with a Toshiba 27" TV model 27a34. I had to replace a zener diode in the chroma section and repair a burnt trace on the board to correct a horizontal width problem. I also had to replace the vertical IC after the vertical collapsed. The set now works correctly other than when I go to start it up for the first time. After I reinstall the chassis I have to press the power button 3-4 times before the set will power up. Once it comes on, and if the set is left plugged in it will power up ok afterwards. But if I were to unplug the set and allow it to discharge the I have to press the power button more than once to get it started again. I went through and resoldered most all of the connections in the set, especially the ones in the power supply section and in the vertical and horizontal sections. I also replaced the on/off push button.
Any help appreciated
Thanks

That model didn't pull up on the toshiba web site.But sounds like it's an older set and just takes a bit to stabilize the standby circiuts.Since it works fine after that I would say your done fixing the set.Don't drive yourself crazy trying to fix a problem thats very minor and not going to hurt the set.

Thanks for the reply,
Unless someone else chimes in with something concrete
I'll consider the set finished. I'll just have to alert the customer
that it may "initially" take a series of clicks of the power button
to first get it started.
