Question about Sony KP-51WS510 51" Rear Projection HDTV-Ready Television

1 Answer

TV comes on predominantly red for 20 seconds then shuts off!

Hi, My set is about 3 years old. When I turn it on it comes up predominantly Red, then the picture starts to come in before going back to red and shutting off. The timer light flashes 8 times. I am not super electronics oriented so I called for service on Sat. Any ideas on what this is, and what it's going to cost to fix? (Sears repairman) Thanks David

You most likely have a bad Red CRT, knowing the age of the set, I suspect all 3 are bad, thats talking $1200 to repair, I would call sony and see if they will do anything with it. (maybe pay for parts or labor?)

Just replaced the bulb with a brand new sony bulb. it takes me almost 20 minutes to get the tv to turn on..i turn it on it turns itself off and red light blinks, and i keep trying until it finally powers...

If red light blinks 3 times when tv refuse to power up then check lamp cover that was removed to replace lamp, make sure lamp cover is fixed in its position securely and screw is tight.
Let me know how many times red light is blinking after three second long pause IF it is not blinking 3 times.

Tv won't turn on. It blinks green then red.

Question shows tv is Sony KDF-60WF655.
Green light blinks when tv gets prepare to fire up lamp, check internal circuits then show picture on front screen.
Red light blinking shows some kind of internal problem during circuit check and protection got activated upon some failure.
Count the red light blink as you will see 3 second long pause and post it here to diagnose what section of tv got problem.
Did you replaced its lamp in last 2-3 years?

Green flashes then tv turns off

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.

Sony Rear Projection TV - Red tube too strong

remove the front speaker assembly and the small access panel behind it and you will see a small square control assembly with 6 dials on it 3 control the color guns and 3 control the 3 gun focus. Try turning down the red control slightly they will be set up just like the CRTs red green and blue.

SCreen turns red then shuts off

The 46H84 has 3 CRTs instead of a lamp. Red, Green and Blue. Your red CRT is shorting out shutting down the set.Here is how you test that theory. Remove the speaker grille, there will be an access panel behind the grille remove that and you will see the CRTs red is usually on the left. hit the power momentarally to locate which tube is red. then power down and unplug the power cord. Carefully remove the tubes Circuit board. ( you may have to carefully slice the glob of silicone applied at the factory to get the circuit board off) Once you have the circuit board off the Red CRT make sure it isnt touching anything and try powering up the set. If the set stays on and the other 2 CRTs light up. That tells you the RED crt is shorted and thats whats shutting your set down. Let me know if I can assist you further.

Have a panasonic 47" HDL projection tv..under 5 years old model # pt-47wx53g, chassis Ap 825,manufactured August 2003 Purchased Oct. 2003. Have cable service..TV works fine until 2 weeks ago. Screen...

3 blinks means the convergence circuits are shutting the set down. Usually the convergence ICs will take care of the problem, but I would recommend getting the service manual from the following link, as they will provide you free support to help you diagnose why it wont start as usually the convergence ICs wont prevent a set from powering up, unless another component in the convergence circuit has failed.

Red?Green picture

You may have inadvertantly loosened a cable connection to the DMD or logic board... You might be able to shut it down, unplug the unit and remove the lamp.. With the lamp out take a good flashlight and shine it into the lamp housing area inside the Tv and see if you have any wire obstructions that you could have contacted with the edge of the housing as you were removing or inserting the lamp...

Panasonic PT-51HX42F

Sometimes, in the Panasonic projection sets, one of the convergence IC's shorts out and draws so much current that one of the resistors next to it glows red hot. The computer senses the extra current and shuts the set back off. This is quite an easy problem to correct, but the set should be serviced by a qualified tech familiar with panasonic projection sets.
