Question about Sony KP43T75GRAY 43" Rear Projection Television

1 Answer

Lost all control......dead

My Sony KP43T75 that was working fine with beautiful picture and sound suddenly is black, no sound, no picture, no controls work, remote doesn't work and the red light on the front of the set stays on, no blinks of any kind. I can't power off the set unless I pull the plug. What's up? Is it worth fixing. The set is about six years old.

Thats an idication that theres a problem in the power supply or the sweep supply. I have seen the picture tubes to leak in this model and cause the boards to short out. These are the type of sets that unless you know what your looking for, Im sorry to say your not going to find it. Your goingg to need a schematic diagram, If you do not know solid state repair or dont know how to read a schematic Im afraid your going to need the assistance of a trained tech for this repair. There is no quick fix Im afraid. good Luck Ps dont forget to rate this please.

Has a beautiful picture, but all of a sudden there is no sound. It was working one minute and the next it wasn't. I use the cable remote to operate the tv, not the tv remote. What should I do?


Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Pull up older posts. Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

No channel set up


Hi, try pressing the "closed caption" button on the remote. I hope that works. If this doesn't work try getting your TV's SE-R0305 Operating manual and reading through it and it might be able to help you. You will be surprised at how much information is in the TVs manual.

Very old set and if red power light stays on and does not blink about a dozen different possible reasons----many parts no longer available for this set----I would retire it and buy a new set.

My KLH 5100 System worked fine for nearly a year. Very suddenly the remote control seems to have no effect on the unit. It doesn't switch it on, or off, or change the volume...nothing. I changed the...


Read this procedure to possibly fix the remote:
http://remotes.com/remotes/servlet/rs?a=Display&contents=help_deadremote&uuid=A12963989782821
They also sell replacement remotes.
Zoom in on the picture of the original remote provided on the site (or look at your own) and get the actual remote model number.

or check eBay: search for "(model of the device or the remote) remote", check the 'include description' box. Usually cheaper than the vendors.
