Hello
Check its power supply regulator board. The pop sound you heard may be due to an explosion to any electrolytic capcitors on it. If the line voltage exceeds, this fault will happen. just repalce the damaged component. It is best to replace this board as card basis.

PROBABLY FAULTY POWER SUPPLY CAPACITORS

AVERAGE REAPIR COST £60 TO £80

The loud pop was a capacitor blowing.

The light is flashing because either power board or ballast board is faulty.

Using the TV in this conditions can cause further damage.

If under warranty contact the manufacturer ringing the number on the user manual

Watching tv all of a sudden loud buzz noise,I shut off unit turned back on loud buzz came back about 30 seconds later loud pop pop then smoke came out of top of unit, i'm not please as this unit i bought about 17 months ago @ Canadian Tire Belleville & warranty is now not covered, pobably will never buy another Proscan product but am more concerned there could be a fire caused buy this than getting unit replaced

Capacitors tend to pop when they fail. Phillips LCD TVs have lots of problems with capacitor failures in their power supplies. I've got my 37mf231d apart on my workbench as we speak. Mine makes a whistling sound which I believe is either a solder fault or a bad capacitor.

A new power supply board is about $150 for that TV. The gamble, of course, is if the power supply took out something else when it failed.

You need to look in your owners manual for the telephone number and order a new bulb. It should cost about $200, but they will ship it overnight and minimize your downtime.

I've replaced 2 in my WD-52525 in the last 3 years, the first one went like yours did, very suddenly, with an audible POP!! The second one was preceded by an orange warning light, which the book says is a warning that the bulb has about 20 hours left on it.

To replace the bulb, UNPLUG THE TV, remove the left speaker screen, with a philips screw driver unscrew the bulb, pull it out by the handle, then replace it with the same type, in reverse order. This is a very easy replacement that does NOT need to be done by a service technician to complete.
