Fault in the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Loud buzzing noise which became a very loud screech over the last week. Turning tv off and on seemed to remedy it. Today screen was only black and white, now no video only audio. Is this the picture...


This TV uses a lamp and color wheel. the color wheel is likely the problem since it is known to make noise over time and will eventually sieze. The repair is in the $400 range.

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.

Loud popping noise


The 23" CRT set may have a high voltage breakdown in the flyback transformer or focus divider. Take the back off and operate the set in a dark room. Look for anything that has a blue glow around it or sparks flying when the pop occurs. I won't guarantee this will find your problem, but it is definitive if you see these!

I once had a set with these symptoms. I stopped the blue glow and arcing by covering the focus divider with epoxy. It worked for a couple of months before the divider literally broke apart.
