Question about Mitsubishi WS-73713 73" Rear Projection Television

1 Answer

TV screen goes blank but power stays on

My 2004 Mitsubishi WS-73713 (rear projection CRT TV) loses picture and sound - the screen goes black but the power stays on. When I turn off the TV and turn it back on right away, the TV works fine for a few minutes before it goes blank again. When I turn off the TV and turn it back on, it works fine for a few minutes before it goes blank again. This keeps repeating.
I have tried all inputs (Comp 1, Comp 2, Input 1, Input 2, Ant-A, Ant-B, DTV) but the problem remains no matter what input is used and what source the picture is from (Antenna, DVD or Satellite).

    Thanks for your quick response. Is this something I can do (I am not a technician nor I have repaired any electronics before). If I need a professional to make a home call, how much time would he/she need to fix it (in case they charge by the hour)?

Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

The green power / timer light keeps flashing on model WS-73713 mitsubishi

when the light constanly flashes, you have a bad digital module, in most cases you can remove the module and replace all of the 1000 microfarad at 16 volt capacitors in it, some have 4, some have 7 capacitors. that usually doea it, but you probably need a repairman.

My tv goes blank with sound only.

tough call. from your decription it could be the tubes the pulsating. but if i had it in the shop i wwould first look at the convergence curcuit. the fact that the on screen display come up in colors inidcates convergence problems. you might have multiple component falure there. as for cost it could be diddicult to say. average repairs like this barring piture tube problem at my shop run 200 labor and about 150 parts. this is just for convergence cuircit rpair

TV screen goes blank but power stays on

There is no way to tell if it needs just resoldering only a couple minutes if the vertical IC is defective most shops will say you need a new Circuit board. thats sad to say but most shops dont do component level repairs anymore, they just switch Circuit boards as they can charge more that way, and not have to reply on having the experience to actually diagnose the problem.Thats very unfortunate but true.
