By the way at some point you will receive an automated phone offer sent by the website ,not by me
Please note that I need time to type and research for parts and info if needed so don't be surprised if there are delays between repliesAlso ,Could you please give me the model number written on the tv`s back cover ?
Sorry but i`m no longer available for this and will repost your question
You don`t have to do anything , your question will be reposted for other techs. to see and jump in.Please just standby and someone should be with you shortly .
When the set cuts off- what do each of the three lights on the front of the set do (please state each one's status- On/Off, Color, and whether Solid or Blinking).
Also are the symptoms 100% the same both before AND after replacing the Lamp?
Okay, so the first one is red, next two are green- and ALL THREE blink?
Okay, this typically happens when there's a failure in the TV (the power supply being the most common)- since a new lamp didn't help. I need some more info- when you first press power- do the fans fire up and does the TV make and attempt to spark the lamp? Also does the picture come on- even for a second? Is there any audio from the TV? Please provide as much detail as possible.
Okay I need some clarification- when you say "lights"- do you mean the Lamp lights up the screen? Also you said "when it gets ready to turn off"- I don't know what you mean by that.
When the picture is on, is the color distorted- anything else worth noting, or does it appear perfectly normal?
This isn't something that can be accurately diagnoses online I'm afraid. The whining noise points to a color wheel fault, or in some cases one of the three fans. Yes the picture appearing perfectly normal would mean the color wheel is fine. That said, you're most likely culprit is the power supply board- but voltage testing within the set using a multi-meter would be needed to narrow it down further. Are you a DIY type with tools and experience and looking to repair this yourself? Or were you looking for a repair estimate, and service locator?
I can understand that, and generally parts are hard to find on these DLP sets since they're not made any longer. With the average cost being in the $350-$400 range, it does make the most sense cost-effectively, to purchase a new set.
Other than that, I'm sorry for the bad news and wish there were a quick fix. Let me know if you need further assistance. Also, before you go, could you please click a POSITIVE RATING (by scrolling all of the way to the top of the page, and clicking 3-5 stars), so that I am credited for working with you today?
You're welcome and all the best.
