Re: Samsung DLP Tv

It's about 3000 to 5000 hrs. on the bulb this translates to about 3 to 5 yrs. of normal use. it can, however, be greatly reduced by the number of on/off conditions. lamps need to cool down that is why the fans run longer after shut down.
obviously if the TV doesn't turn on that can be lamp. weak or dim picture is another sign.

My Samsung tv is dim; has sound and we can see the tv its just very dim. Its not a setting; we already chevjed that.

If the TV unit that you have is a DLP than a bulb in the rear is the likely culprit and is burning out. The bulbs lasts for thousands of hours but over that period the light output reduces.

The procedure for replacing is relatively simple. Use good safety procedures including disconnecting the power cord. My suggestion is you purchase a very good quality replacement bulb installed into the module. You want the brightest bulb to get the best results,

Bulb replacement type

I'd search ebay, amazon and for a replacement as that one is probably not compatible with your model. Find a user manual for your TV, they aren't hard to replace yourself

How to tell if ballast is bad on samsung dlp tv

It is a common practice that the ballast to repalce along with new bulb. There is no way to check the internal winding short of ballast. Repalce both at the same time. If ballast has any damage, it will surely ruin the bulb too.

How about ru-52sz51d ?

I've dealt with DLP projectors and TVs for over two years and never had to send out a technician to calibrate after a bulb replacement unless of course the light engine has been jolted out of position. You may be looking for more than just a calibration, you may need repair service. Calibration was common with front/rear projection TV's when they used 3 lenses. DLP only uses one so other than focus and color adjustments, regular calibration shouldn't be necessary unless something is wrong inside.
