How can I replace the thermistor or lamp power supply in my Mitsubishi DLP 62525 TV?
Posted by admin in led dlp tv
When I turned it on the screen lit up briefly, faded out, almost came on again & then went black. The red lamp bulb came on. I replaced bulb assembly, but when I start it up it tries to come on, but no light whatsoever, then that darn red light comes on & stays on. I have triple checked to make sure it is plugged in securely. I figure it must be power supply or something else that is not getting power to lamp. I assume new bulb is good; there is not any continuity between the plug prongs like I would expect in a "regular" bulb; I haven’t taken the thing apart to check any actual bulb leads.
Are you an experienced service engineer? The problem is somewhere else and not as you think. Have you got the circuit diagram of the TV. Check the circuit for correct voltages in all the places.
Still no solution! Call/consult with an experienced service engineer.
Does anyone know what causes the LED’s on a DLP TV to let you know the lamp is going bad? Take for instance that you replace your DLP lamp. Now your TV is good for 2000-5000 hours. When the lamp is going bad the LED’s start to flash and TV shuts down. All you do is replace the lamp and do not reset anything, and it works fine. How is it possible that the TV knows that the new lamp is in. If the old lamp is still good but the timer goes off can it be reset to get maxium life out of Lamp and just not off the timer. I tried to take old lamp out and put it back in to see if anything would reset. I had no luck. I have seach all over for schimatics on the PT50DL24 Akai 50inch and no luck. Any TV service personal out there can you explain to me the logics behind the DLP lamps. Thanks
Not only DLP, any LAMP based TV works the same way.
They meassure current comsumption for the lamp.
Lamp’s resistance is normally low, but as you use it the internal electrodes degenerate and that increases the resistance…. this means the lamp consumes less current (hence less brightness on the screen). The circuitry senses the current consumption. When it falls below a treshold value the circuitry knows that it is time for change and will proceed to flash the correspondent LED and shutdown the TV.
A new lamp has a small resistance so it consumes more current… When you install a new lamp the current increases again and the circuitry knows that lamp is ok and let the TV work.
I’m looking into getting an LED technology. I don’t intend to hang it on the wall and perfer to get more size for a better price with 3d technology. However I’ve heard the DLP bulbs burn out and are expensive. The solution are LED’s but it seems the number of these tvs on the market are dwindling. whats the deal? Is this really the case? Information from nextag.com 61" LED —# of sellers.
what’s the downside to LED’s? Apart from being able to mount it to a wall which I could care less about…its seems you can’t beat the price
I’m looking at projection DLP tv’s with an LED bulb
there not that good
What brand is the best for DLP TV’s. Should i get the LED DLP or just the standard DLP. i was loking at a Samsung HLT5087SAX 50-inch Slim LED Engine 1080p DLP HDTV. but there was a post about how the tv died in less than 2 months, and then the man got a new one and it died in less than two months. Note: i will mainly be using this tv for gaming and movie watching
what ever you do do not buy an off brand name. they don’t make parts for them and they don’t have service centers for them. they have earned the nickname "disposable TVs" spend the extra money and buy a good trusted brand name.
