Question about Sony KP-51WS500 51" Rear Projection Television

1 Answer

Sony KP-51WS500 will not turn on

When I press the power button it sounds like the tv is turning on but the screen stays black. The red light flashes 3 times, then a short pause, then flashes 7 times very fast, then a longer pause & then flashes 6 times (slower than the 7 quick flashes....same speed as the initial 3 flashes) and then pauses & continues repeating the 6 flash cycle. Is this thing even worth attempting to fix? Many thanks for any help or advice I can get.

I believe the problem is either in the G board ( power supply) or the D Board ( high voltage) as the 3 blinks indicate the G board, and 7 indicates the D board and 6 indicates the +5 line a and b boards. So with that many codes its most likely the G board (power supply) You can get a new replacement G board at the following link which comes with free tech support to help you plug the baord in which is very easy. Its listed under the Sony parts category and its the A-1316-566-A sony G board, Here is the link.

Screen turns red then shuts off


Sounds like a bad red projection tube, disconnect red tube socket and try again if tv stays on reconnect tube soket and adjust screen controls on front of tv under the front panel which you will have to remove to do any of this. There are six adjustment controls 3 are for focus for each color and 3 screen controls for each color. Look close at the black plastic control module should be labled R G B for focus and R G B for screens. Good Luck!

Sounds like from your description the Blue CRT ( picture tube ) is shorted. I believe they are no linger available. If in doubt, I would call a service company to verify this.

Hi, you will have to replace the convergence circuit board on this unit. it is failing to calibrate the rgb stream.I'm sensing signal board failure as well.

Faint red curved lines on Sony KP 51ws500.Converged = no work???


Hi There!
This sounds like a typical problem related to a older CRT.
If you remove the front cover of the tv, you can then remove a wood panel. Behind this panel you will see a block (high voltage splitter) it will have 6 "knobs" on it, 3 will say focus, 3 will say screen.
They will also be labeled R - G - B  
Put the tv on a blank input so you can see the lines clearly on a black screen  - Find the knob for red, and SLIGHTLY turn it down until the red lines disappear.
