Re: screen flashing

You need the voltage on the ps board and the ysustain board adjusted. Possibly the z sustain board needs replaced if this doesn't fix.

I have plasma tv thats has been getting the pink bands across the screen when the image on screen is bright. It gets worse when cell light is turned up in addition to brightness.

You need to check all voltages there is a sticker on the back of the screen with various voltages these need checking with a digital meter.

High Def input search

It sounds like you arent using the correct ports for a HD tv or arent using a HD digital player or HD cable. Still having problem let me know but thats what it looks like to me. Do you have anything plugged into these ports from a HD device? DVD,Digital Recorder, etc?

Samsung LCD TV 46 inch model LN46A550 has bright pink glow where it should be light (sky, lamp, etc)

My guess would be that you have a CCFL lamp that is failing. They will give off a pinkish tint when they are about to fail. But I would encourage you to get a professional diagnoses.

Flashing screen on Toshiba 42HP66

Plasma sets use high voltage to produce their displays and it sounds very much like the HV supply is losing (or has lost) regulation likely due to the impending failure of a semiconductor.Check to see if Toshiba has any extended warranty on this since it could be a series problem.If there is none, ask for a price on a new or repaired supply on an exchange basis.

I own a 5 year old 40" sony bravia lcd tv, When

This sounds like what I managed to do to my screen, even though I knew better. Is there any chance you layed the screen face down at some time?

Even though you can still watch it OK, you probably have hairline fractures in the screen face (NOT the screen itself- be thankful for that- the cracks are in the screen coating). LCD screens are a very thin glass laminate with a thin protective glass-like coating. When they are laid flat (like I did to connect cables) if the screen bears any weight, microcracks develop on the front of the screen.

I am sorry to say that the effect is permanent.

900 hours and I am seeing some image retention. How to remove them?

In a few words, you can't.
Panasonic Plasma Screens have a movement option that slowly moves the screen around a few milimetres
I the burning is bad and all you can see is Sky TV's frames or Sport frames, the way to reduce the effect, and this is official, is to turn up the screen brightness on a white background. This will burn the rest of the screen to a similar level!
Unbelievable but having done that for a number of hours, when one increases the brightness to compensate for a burnt screen, it is slightly better.
(I do not advocate that, I would not let it burn in the first place.)

Good luck
Hope that helps.

Bravia & Sky+HD, aspect problem

There is nothing wrong with you Sony Bravia TV and it suppport all HD and SD formats.

Are you viewing the HD version of the channel when it is showing a standard defination show. e.g SKY1 HD instead of SKY1.

This means that regular standard defination shows are in a 4:3 ratio and does not fill the whole screen. In order to view these type of shows you will need to tune to regular channel instead of the HD version.

You can check if a show is brocast in HD by going into the tv guide and checking for the HD symbol in the programme symposis.

Picture Flashing

I have a similar problem but my picture flashes black and white and the sound goes at the same. Also sometimes it will flash pink and blue. I've read elsewhere that the issue is a known problem with compatability between Samsung tv's and sky boxes. Apparently the box needs to be replaced but I'm unsure what type of box. I've read perhaps a PACE sky box could fix the problem. I think the best option would be to contact Samsung - that's what I'm going to do.
