Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

Pink and purple picture

I changed my bulb on the t.v. due to the picture going darker and darker. It worked perfectly for two days. When I turned it on today I have an immediate picture that is bright but it has pink/purple over tones. I've adjusted the setting and even turned it back to original settings. It is a 50" Sony KDF-B50A10 . Any info will help as I'm not sure if I want to sink more money into it.

Picture has slowly gotten darker

It's time to change the projection bulb. You need to go to and search for tv bulb with model number of your TV. Now the tricky part is to try to get the bulb with the longest warranty. Don't get one with a 30 day cause the bulb may go bad by then. Get one with at least 120 days. As well read the reviews and make sure the other customers are happy.

Changing the bulb is easy and only requires a Philips screwdriver. There are YouTube videos to show you how. But these bulbs are very special and blow easily, so get one with a long warranty. And don't get a spare, cause by the time you need it, the warranty period will be up.

The pictures are coming out pink

This is usually due to ink cartridges going bad or being empty. If you have not changed them, this is the first thing to do.

I hope this resolves your issue. Please let us know if you have any further questions.

Does the Samsung PN58B650 need a minute to warm up the first time you turn it on every day? When I turn on the TV for the first time every day, the picture is there but the colors on the screen are pink...

I swapped out the HDMI cable with standard component cables. The picture and sound is perfect. Later I will swap again with a different HDMI cable to confirm if the problem is a bad cable or if the TV has a problem with HDMI.

Picture blacks out after a few seconds after turning on the tv

Anytime an LCD has a shade of pink, that means the CCFL lamps are about to go out. Now that you have a black screen, I'd say you just need some new bulbs.

Washer agitates as soon as it is turned on

Boats, sounds like the pressure switch is not operating right, anyway, start there, look at the picture, its the round one on the left with the hose going to it. It has 3 wires going to it, purple (line going in) pink (to water inlet) and tan to motor. Should have 120V to purple and pink, no voltage to purple and tan while filling. Once filled 120V to purple and tan but no voltage to purple and pink. You can also ohm it out by pushing in on the clip and twisting it off. Should show no continuity from the two outer terminals. Blow into the switch and it should show continuity. I think the switch is sending voltage to the motor. Anyway, check that out first and post back. Catriver
