Neon sign lights up inconsistently

I bought a great Pabst neon (3 color). Most of the time it is off. When Friday night comes and I want a Pabst I turn it on. The problem is that I have to pull the switch a few times, and un-plug it, and then plug it in a few times. It will flicker, while doing this. After about 10 min of trying (I always wait a min, and give it a chance to "warm up"), it will turn on. Do I need to get it fixed? It seems to be getting worse, taking more and more time to start up. I just love the sign, can you help?

    Hi teddysexton, I want to help you with your question, but I need more information from you. Can you please add details in the comment box?
    so how old is it, ? 1year 10 , 100 years
    1920 first true neon signs in USA>
    i guess home toy sign?
    or is it a modern sign (LED simulated NEON)
    as in look ma' no real neon here?
    I will answer you for true neon
    there are 2 causes (I had one as a kid in 1955)

    the neon gas is now bad inside, leaked out.
    happens. on cheaper tubes
    all have life span not too long
    the best last a few decades.
    the best tubes are heat processed when new for longer life. (RF induction)Just like Radio vacuum tubes, were, See my icon here this is huge RADIO TX tube with nitrogen leak purple.

    next is bad transformer. weak.
    not told at all how many tubes are there
    1 or more and if more are all acting up?
    just one color? or only neon orange.

    a real display has real lable to tell who made it and a model. toys not so...much....

    "warm up"
    is it cold where the sign is, not told
    yes warm tubes start more easy.
    but if the HV transformer is weak it fails
    to ionize the neon// bingo that xfr bad.

    some transformers are just flat 15k volts
    others have starter the get it started using HV then drops to lower voltages but the length and diameter of the tube dictates needs.

    life spans

    lifespan of 10,000 to 25,000 hours

    so 8 hours per night in BAR would be 6 years and dead. 17hours math
    before ***** they act up, just like the huge fluorescent lamps do.

Did Russian companies buy pbr and Rainer beer

Yes, Pabst Blue Ribbon - a sub-premium beer brand that embraced savvy marketing to stay relevant in a craft beer age - has been sold, along with its parent, Pabst Brewing Co., to Russian company Oasis Beverages.
The companies declined to disclose the sale price, but beverage industry analysts estimate the sale at nearly $750 million - a figure nearly three times the estimated $250 million that C. Dean Metropoulos & Co. paid for it in 2010. Oasis Beverages' partner in the purchase is TSG Consumer Partners, a consumer products company that will take a minority stake Pabst.
Besides the familiar Pabst Blue Ribbon label, Pabst Brewing Co. makes Colt 45, Old Milwaukee and Schlitz. It also makes regional brews such as Lone Star, Rainier and Old Style.

Problems taking photos at night.

Did you use flash? Did you use tripod? Generally speaking night photos with non-DSLR digital camera, W55 is non-DSLR, will be blurry unless either flash is used or a tripod is used. The issue is the camera shutter is set for a long exposure in order to get enough light that it is impossible to hold the camera steady. The color problem you mentioned is most likely your white balance. Normal white balance is sunlight at night you white balance should be Auto, Incandescent or Neon
