RCA HD50LPW164 turned on TV made a pop


the loud pop you heard was probably a capacitor blowing its top. The grinding noise is likely high voltage arching that was occuring due to rising voltage since capacitor isn't there to smooth it out.

if the noise is from inside the tv in the back,the high voltage transformer that feeds the anode for the rgb tubes,28000volts probably is arcing.

My W3201C 32" LCD TV made a loud popping noise when I turned it off. Now it will not turn on. No power. No LED light.


That would be your transformer popping and dieing. Usually the popping is followed by a burning smell which is a good indicator that the part is unrecoverable. The cost of the part is variable based on the make and model TV and is usually not too labor intensive to replace. If not under warranty, let the repair gut know that you know what the problem is. Then, ask them to quote the cost of the replacement part and part number. Then ask them to quote you their hourly rate and get a time estimate. Then, google the part number and see if the cost is reasonable.

Tv went out after loud pop and has clicking noise does not turn on


If you have a Sony DLP, then the loud pop you heard is your lamp.  The lamps last approx. 4K-6K viewing hours.  Read your manual for replacement part number to reorder and very simple to replace yourself.

My TV


The loud pop was the $300 bulb exploding. Don't look for any help from Toshiba either. Their customer service stinks as bad as their product. Put the bulb in yourself and then sell to the next ****** that comes along. I made the mistake of keeping mine, because I thought that Toshiba was still a good product. Wrong, next the color wheel went out. It was back ordered forever. When I finally got one I installed it myself. So, it would only cost me the $530 price of the part with out the $400 charge for labor. Run as fast as you can. I now have vertical lines on the screen after 2 weeks. Who knows what's wrong now.

TV won't power up. I herd a popping noise and now the TV won't turn on.


A popping sound can be a good thing because it will be easy to identify a blown up or degraded component,if you are familiar with tv service you might spot the bad part fast just by looking at it and then change it,sometimes you actually have to check a component with a meter to tell is gone bad,check the main fuse ,it should be close to were the power cord comes in,if is black you will have bad components ahead and you will need the assistance of a servicer,if you are not too familiar be safe and call for help.Let Us know how it goes.
