Open Question

Tv flickers/blink i have a sony kp 41s4u rear projection tv. when the tv is switched on the television flickers on all channels. the only way we can find to stop this is to turn down the contrast and brightness which then stops the flickering but the picture is really dark, if something prominent in white comes on then it flickers again. can anyone suggest anything please. teresa

Hi Guys

Your problem here has to do with the amount of aging that happens to the three colour tubes - red, green and blue.

Blue actually ages slower than red and green. What actually happens is the green tube deteriorates and due to green being the predominant colour for brightness causes the blue tube`s flyback lines to appear - especially when switching between inputs or when the video is blanked.

No replacing the blue tube will not solve your problem as the tube is actually the best one of the three.

As someone mentioned there is a way to adjust this by removing the speaker grill assembly in front of the set. Doing the service mode adjustment with the remote is not the right way to solve the problem - you would be adjusting the colour gain and off-set values and would seriously be compromising the white balance of the set.

On the left hand side behind the speaker cover you will see a black square block with six adjustment points. Look for the one marked SCR BLUE, Switch the set to a unused input so the blue lines become visible. Now adjust the BLUE point counter clockwise until the lines disappear. A small adjustment should do it, Switch back to a picture and make sure the whites are still white.

This should sort your problem. I would however suggest asking a Sony service centre to do this for you. This is a dangerous thing to do as you will be working close to the 35Kv supply the the anodes of the three tubes.

I hope this answers your question.

Goo luck.

These sets have been known to have loose welds in the picture tubes. Most likely your tubes are showing this problem.

Have you replaced the lamp? That's the first thing I would try.

The first thing to do is to rescan for channels. If for some reason the channel memory got wiped out, there could be no other "available" channels to change to. The "flicker" you see is the TV changing to the same channel. Try the rescan and update this if that does not resolve the problem. Let's eliminate the simple stuff first. If the rescan DOES resolve the problem, please update this with that information as well and we will try to find out what cleared out the channel memory.

THe standby light will blink a code that should be a repeating code. Please post the count here as that indicates which circuit has the fault. That info coupled with the model number above will allow us to explain what is broken and perhaps what parts need to be changed to fix it.
