You must look around for the reson of this burning look for burnt resisttor--explosive capacitor-----short circuit capacitors----short of winding in pulse transformer-----circuit diagram will be helpful.

Why is the t-con board in my Toshiba Reza 42HL67 LCD TV repeatedly dying?

Could be just bad luck! It seems unlikely to me that the power supply would take nearly a year to destroy the T-con board!
You could get in touch with Toshiba to see if there is some kind of problem that is cropping up on this model that might cause failure in on the T-con.

Never leave an image on a DLP tv, It will burn into the screen

Ok I had a problem with a banding on a 57 inch sony DLP, It was burn in from thr ticked that runs on CNBC when I was trading everyday. It took the 8 months to return the set after 6 tries at trying to get me to accept it, The ended up changing all 3 guns, the power board, and the front glass which they cracked one time and scratched the second,I was on a first name basis with the VP from the chain store. She was a very nice lady and we became friends. Meanwile the final time the forgot to scre the wheels back on, so they called 2 more techs to tilt it while one screwed in the wheels. Two days later the same thing happened, the VP told me they had spent over $2000.00 dollars on a 1,500.00, dollar tv. She sent me a gift card for a new set and that was that, Both Dlp's and Plasmas will, Burn an image onto the screen within 15 minutes. I only suggest LCD tv's. Especially if you pause things and forget or they are on, video games, especially, you will surelly screw it up. There may have been a ticker scrolling or a paused show on your set and it may be burned into the screen or gun itself. Even pictures from your camera will do it, most manufacturers leave themselves an out even on the sets tha say they are burn in proof. Do,not buy Plasma or DLP tv's, they all have burn in problems even if the salesman tells you different, A simple search will bring up hundreds of articles from folks who were not made aware of this.

Lost power, now that it is back on, i can not get the power on the tv to work, i tried both the remote and the power button on the tv itself. Any suggestions?

If you had a power outage (from what I've deciphered), you may have a broken TV on your hands.
If it happens to be a LCD TV, it maybe a mildly simple fix, as in changing the LCD inverter, or power supply.
if your TV has indicator lights to show if the TV is on, but no light is coming on when you press power, then most likely power inverter. if the light turns on, then turns another color, its most likely the power inverter.

If you don't have the heart to rip open your own electronics, a repair shop is the next best thing.
But, parts are cheaper bought online, so if you have a friend with some experience, it might be the right time to make some calls.

Hope that helped,

I have Logitech R-10 speakers, which sudenly stop working after 1 year of using. Although I have not used it frequently. There is no power/current going through as the indicator (light on it) do not light...

Open the case, see for the power board, look at the fuse, is it burned or not, if burned, try replacing it with the new ones, if don't, then you should check on everything intensively.
I hope you know how to use multimeter ( I suggest the analog type ), it's useful enough to solve this problem.

First thing check on the power cable, is it good or not.
Then check on the Power Transformator, burned or not.
If it's OK, and you must measure the tranformator output through diode using DCV on multimeter, it's should around 12 VDC-24VDC, if it's OK, then check for the switch, sometimes here's the problem occur.

If all is OK, then you should replace the Power IC on the output circuit, to locate it, just look at the component that attach on aluminum/ heat sink, replace this IC will solve the problem.

My klipsch sub 10 has no power

If it burns out with no signal going to it, then it could be the + and - power leads are reversed. Otherwise, it's probably an internal component failure requiring a tech to fix.

If it burns out with a signal going to it: Very likely the amp is overloaded and goes into protective thermal shutdown. Letting it cool off for a little while would allow it to reset. could be it's not capable of sustained power level you like.

Next most likely reason is miswiring speakers - if you have more than one and they are in parallel (the usual case, with all the red+ terminals wired together and all of the black- terminals wired together), check to see that their total impedance is no less than the minimum specified in the amp's manual. The total impedance is Z=1/(1/Z1)+(1/Z2)+(1/Z3)... where Z1 is the impedance of the first speaker, Z2 the second, etc. For example, two 4 ohm speakers in parallel = 2 ohms.

Remote has stopped working for Philips LX3000 D

The remote control might be damaged. If it is possible to arrange a new remote for testing, do it. volume control of LX3000D works from the front PCB. check the front PCB is perfectly ok or not. Regarding the DVD player, what it says when you try to load a disk?
