The caps (capacitors) in the powerboard are going out. This is a very common problem in all class and price ranges of modern lcd and plasma tv's/ monitor's. I don't know if this problem has been like this for awhile or it just started, but either way, if the tv takes an abnormal amount of time to "warm" up then it most likely will go out all the way sometime in the (near) future. If you have a tiny bit of will and knowledge ypou can open the unit and get to the print board. Examine this for "popped" capacitors, they will have a buldging top instead of a flat one. Im gonna try to include a pic of them here, if i can get it this time, I've tried bfore lol. But you can google image a "popped" or "bad" capacitor and you would be able, with ease, to diagnose if you have any of these. Usually only one or two. Radioshack sells capacitors (couple anyway) for $1.59 each. MAKE SURE the replacement is of the SAME voltage or HIGHER, or you will be right back replacing those 2. Every capacitor has a negative pole marked with an (-) on the side of the capacitor(by one of the "legs", always puit the negative (-) "leg" of the new capacitor in the same hole in the printboard as where the previous negative (-) "leg" of the capacitor was ( a capacitor with the negative and positive "legs" put in backwards will result in the new piece "popping" as sson as you turn it on!!) make sure the "uf" rating (for example the most common popped capacitor is the 1000 uf) is the same as the one you are replacing. I needed 1000 uf, 105 c and 26v (volt) ratings for the 1 capacitor I needed to replace to fix my LG 19" lcd panel monitor I found by the trash that the light came on off, but it didn't come on. I replaced that capacitor with ; 1000uf, 85 c and 36 v (volts0...It works fine eventhough the volts and the temperature rating (36v and 85c) was not the same as the (26v(volt) and 105c ) capacitor I removed !! Further, I've replaced capacitors that had the celcius rating of 105 with the only ones Radioshack had, namely 85 c(celsius) they have been working great, but I'm not sure about any effect, nor have I heard or read (yet?) about that making an urgent difference. Many threads that I've read people have done the same, so we should be ok (my stuff has been running good for a while longer then most brand new ones!.............(all these ratings ; 'uf ' and 'c' etc are on the side of the capacitor you are replacing and on the side of the ones you are replacing them with)...For all this all you need is the cheapest solder gun u can find (I bought one for $7.99 at Radioshack), a camera (to take pictures as you go to remember how to reassemble the unit) and, once you have your materials, 20 minutes to replace 2 or 3 capacitors and you are good to go...Most monitors and tvs (lcd/plasma) I've seen you have to lay flat on the ground/bed/blanket etc, to work on (screen side down). Usually there are 2 or 3 screws (or a few more) to remove, then you will have to carefully (its comes off easily most times)insert a flat screwdriver inbetween the casing and gently pry it up as you go around the whole frame. Sometimes you have to remove the little washer arouind the cable input orso, just be gentle and you cant go wrong. Once insidet here will be a box with wires running to the sides etc...unplug, gently, these wires and open the box. Inside you will find 2 or 3 circuitboards, check them all for "popped" capacitors, replace, reassemble and plug it in....Have fun becoming an overnight tv mechanic lol!
If this helped (or not)please rate, thank you!
Testimonial: "Thank you, thank you, thank you. I'll look into the cap issue as soon as I can."
Your welcome, Ps if you are desperate for a tv, try pointing a fan (box or stand-up type-it doesn't matter) on the back on at least medium speed, then turn the tv on (u'r hoping anyway :S). Cooling it down could slow the process of the capacitors burning out, sometimes even a tiny bit of extra airflow could've prevented the problem in the first place... Your tv might be past this "lifesupport"point....I have a 32" Poloroid lcd that I'm typing this on right now that has a box fan blowing gently on the back. I bought it off Craigslist for cheap, Seller came over to deliver, we plugged it in, looked good, except for the sound not working and the cable input not working(monitor only)), but that was how it was advertised...So I was happy, then after about 30 minutes (and the seller looong gone lol) it shut off, everytime I turned it back on it would switch off even sooner. I bummed, but it occured to me that , since the time "on" was getting shorter and shorter, that it prob was overheating. I placed a fan behind it and now here it still is , 3 weeks later. (why fix it when it works now, right!?)
I think I finally figured out how to post my pic of the bad capacitors...here it goes....

Just went through this,all the solder connections on the bottom of the circuit board need to be re-soldered. I unplugged it for an extended period and apparently the contraction of the older solder joints made them separate.You can do it yourself if youi're real handy other wise its about $175 in Denver...Jim Lynch
Hello,
My LOEWE CAL 232 will not power up. When the power button is pressed, the monitor turns on, with the LOEWE on the monitor, then the TV continues with the previous activity (antenna, DVD, VCR etc.). Now all that happens is
1. the red light comes on
2.after about 1 second the green light turns on for about 12 seconds
3. the the green light turns off for about 1 second
4. then the green light turns on again for about 12 seconds
and this continues until the power button is pressed to turn the TV off. During this time, the monitor does not turn on and the only sound I hear seems to eminate from the power button.
Any thoughts?
