No,not repairable,because the front screen panel are 90% of the tv,sorry ur tv now,it only can be salvage for electronic boards for parts,that it.The tv screen panels are only can be purcharse from the tvs corporation themselves.They'll charge u the screen panel the same priced as new tv.Because the tv screen panels are in limited production and 90% improtant to the tv,that why.

You may view/download the manual at Owners Manual User Guide for Sony KP 51HW40 51 Rear Projection Television The Setup menu is on page 58.

You need to do a lamp time reset in the menu.

Possible blown capacitors on circuit boards in the TV or power supply if it's separate.

I would check fuse and Power supply first

Hello, you can go into the menu and rename the inputs to what you want example: input 1 can be cable box, input 2 DVD etc. In the menu, go to "inputs" to the side of each input there are several name choices to choose from....tks

I think its battery has some problem. If it is genuine remote of the TV then you should take it to the technician.

on the mainboard (green board) whilst the tv is on but it dosent matter if the screen is black.. feel the main chip... it should be silver and big in metal... feel if it is hot if it is very hot then your tv is overheating and might need a fan at the back or new mainboard

Your convergence has failed. This is a very common problem on most projection tv sets. You can read about it here on fixya using this linkhttp://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull-----------------------------------------------------------------------------------------------

thats the white balance failure which is usualy caused by a failed Video out IC on either the Red, Green or Blue CRT drive boards.

Here ya go.

or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

It is a set with issues with the 3 picture tubes but it is quite likely if you locate the red screen control and turn it down just a little you can correct this problem.

First is the model listed here does not use a bulb, it has 3 picture tubes. What is actual model number as I think wrong one is listed here.
