Willihen59,

The most likely problem is your lamp has failed. If you haven't looked at it yet I have a tip at http://www.fixya.com/support/r4168009-change_lamp_in_dlp_projection_tv which explains the procedure for changing the lamp. If the lamp is exploded and you replace it and the unit still will not start I have a tip at http://www.fixya.com/support/r4168009-change_lamp_in_dlp_projection_tv which will help you troubleshoot any additional problems.

Thanks for using FixYa and for the great rating.

I have a Vizio p50hdm while watching heard a pop noise and tv went out cant turn back on.I replaced main board and power board and still doesn't come on any Ideas?


The power amplifier chip (which goes "pop" when it goes bad) may be located on the board where the IR sensor is. Sometimes (but not always) you can make the TV come on by holding the power button in _until_ the TV comes on. But that usually only works when the chip is "going" bad. If you heard the pop, it's probably shot. Also, check for a fuse on _any_ of the boards, and possibly a main fuse at the back of the TV.

Sounds like the color wheel or lamp I would check the lamp first to insure thats its not broken as they can make a pop when they fail sometime (Breaking) then I would check the color wheel you will be able to tell if the color wheel arear has the noise coming from it.

We heard a "pop" noise


The pop noise could be a capacitor poping its top up.This is a common problem to most TV sets today. Usually located at the power supply board.Once this parts give up it usually shorts the circuit and blows a fuse.Replacements of these parts mentioned will often remedy the problem.Flashing power indicators indicate a problem.If you have the chance of counting how many the blinks are I could have told you the problems code are and the source of the problem.

Samsung hlr5078wx DLP tv. rumbling noise and shaky picture


This is a color wheel problem.
I would recommend to use professional help because you can make more damage to the optical engine. Not to mention index delay have to be re-adjusted in special service menu after repair is complete.

Hi
Sounds like your oven heater failed. Not sure if its a fan oven or static type. If you hear a fan inside the oven then its classed as a fan oven

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.

Read replace lamp then afew weeks later heard pop noise and now black screen


Two things in your TV can make that popping sound. One is the bulb of course and the other is a capacitor. Have you pulled out the bulb to inspect it? My guess is that you have broken glass in the cooling fan, which is why there is a grinding sound. Most bulbs tend to contain the glass from getting everywhere as it's only the filament inside that pops creating little diamond looking pieces inside the lens. If a surge was strong enough or if the bulb was poorly manufactured, the whole unit can explode inside spraying glass everywhere.

If the bulb looks fine, the pop must've been a capacitor on one of your circuit boards resulting in no display. Since the TV still powers on, your power supply and it's fuse appear to be fine. Check the bulb first and go from there.

Wont turn on


sounds like the tube is out. could be the transformer but probably not. I don't recommend you try fixing this yourself.

However some rcas are funny: unplug it again and leave it unplugged for about an hour then try again.
