Please help! My TV was on and it started make a sound that I wasn't familar to me and then the picture and the sound went out. Now it won't come back on! Thank You! Mbahero1995@yahool.com


was the sound a poping sound or squealing sound? Sounds like the power supply. if you have experience - pull the rear panel and check the power supply for bulged/leaking or busted caps - if not replace the power supply using the part number from it. be careful though the voltages and amperage can kill you.

thanks,
michael

You are hearing the main POWER relay turning on and off, it can be caused by short circuits so it turns off then turns itself back on, or the power supply DC is not steady due to bad caps, it will have to be troubleshoot down to component level, most repair shop will try out a spare power supply module.

TV will not power on.


I guess your TV is DLP.
Please notice the follow symthoms:
When you on TV, did you hear some strange noise from the back of the TV. If yes, the color wheel needs replacing.
If no, check the lamp. Take a look to bottom of lamp, you will see white pot or sometime a pop up there due to lamp cycle is going to end. When changing lamp, check the ballast and power sup, too. If you see caps are poping up. Pull out those board and replace the poped caps.

DYNEX 32" LCD TV POPING


If it is from the inside of the tv if it is its never a good sign and you should turn it off immediatly and unplug. if its just the speakers it still isnt good but it might just be a faulty cord. Take it back ASAP to where you brought it and explain your problem

If you have any questions please dont hesitate to ask
