SOURCE: Flickering Picture?

Your set might have a high voltage leak and that is the noise you hear when is showing the screen problem or even maybe an arking too ,either one is related to the high voltage and it can be dangerous,if you are familiar with tv service you can try to see where is arking and replace the part with an exact replacement but if the set has a leak you will not see it and is not safe to be close to it,if you are not too familiar be safe and call for assistance from a servicer.

SOURCE: When tv is turned on picture flickers really

When it goes black can you see a ghost image? It will be a normal tv picture but very faint black and white looking, you may have to get close and look at an angle to even see it. If so that means your backlight system is failing. If you don;t see an image then it is a problem with the power section of the board inside the tv.

Check if it is covered by warrenty and get a quote if it isn't. A 42 inch is new and big enough that it should still be worth repairing but it may cost you anywhere from $100 to $250 depending on the shop to fix.

Picture flickers on Sony HDTV


Hi,It seems your ballast(board that powers light bulb) is going weak.The ballast was used to provide a lower voltage because lamp didn't use as much as brand new one. A newer one takes more voltage and when ballast doesn't provide as much power it will flicker or produce a dimmer image.I found the one for your tv here: http://www.discount-merchant.com/1091041-KDS-60A3000-p/1091041.htm?Click=48173 Good luck and God bless you!

Sony KP75HW40 unstable red. (not the usual problem)


I would suggest either the Focus block or the RED CRT drive board either one of those items could cause the symptom. A defective CRT could also, but a shorted CRT doesnt usually go back to being normal

Color flickers on and off


I went to the Sony support page for your model.(link below)http://esupport.sony.com/US/perl/model-home.pl?mdl=KP61V85&LOC=3
They are undergoing maintenance right now, so I couldn't find any answers for you. I would check back with the website to see if they can help you. If the Standby timer light flashes, you may need to have the TV repaired. There is a "Hot Topics" section for "How to troubleshoot television picture issues" that will probably be very helpful to you.

DLP TV starts to loose picture after 1 - 1/2 hours of use


This tv has a 3 board video path. Analog main pcb --->Digital main pcb --->DMD pcb. see which inputs have the problem to narrow it down. if only some inputs, suspect analog board. if everything flickers(all inputs and menu), suspect the dmd or engine. you can see the lamp shine out the back. if the lamp is flickering, suspect lamp or ballast.

Sony 57"


This is almost one I'd prefer not to answer because it's not good news and usually posters just kill the messenger.
In this particular model sony the focus block P/N 8-598-955-31 are common failures which can cause the flickering but not usually shutdown. Also a common failure is the crts used in making this unit and they are not economically repairable. The symptoms there are exactly what you've described, flickering then shutdown. The flickering is caused by current leakage in the crt and are especially prevalent in serial numbers beginning with 90xxxx. Sony even put out a bulletin on this issue some time ago and offered part warranty on the parts for replacement. That offer has since expired.
You can remove the lower front panel and expose the lower area of the crts and focus block. If you take the the rubber end of a screw driver and slightly tap on the neck of each crt while watching Tv you can confirm the described failure of the crt if it flickers as you tap. We techs call this the slap and tickle method but it is VERY effective in this case. This does not in ANY way rule out having it diagnosed by a qualified technician, which I strongly suggest, it simply helps in confirming the diagnosis yourself.
Sorry
Bill

TV Flickers up and down and screen is shifted to the right w/ red color dominating the screen.


Hi
The most likely problem is the auto focus module.
A costly repair.
If you are going to fix it ask for a rebuilt one.
