Picture disappear while sound still on?


My first go-to place would be any connectors you removed when you did the repairs -- as since this happened after a period of successfull run-time, HEAT may have caused them to expand to the point where a minimally-connected contact is failing. (And I admire your tenacity on taking on a job like that in the first place!)

Prima Cineplus 50" Plasma PH-50R18C will not turn on


The ambient temperature might be high. Check whether the foolinf fans are working or not. If not, check out the reason for it. The TV must be placed at least 6cm away from wall, and should have sufficant ventilaation.

TV is working beautifully then the screen goes dark for 3-15 seconds and then the image reappears in beautiful HD. The TV is two years old and otherwise works perfectly


Technology changes at a high rate of speed, as we all know. And High Definition (HD) has come a long way in a very short period. Since your television still works perfectly otherwise, I don't think that it's a problem with the set itself. It may only be a victim of technology.

Does this only happen with High Def channels? Does it happen every time you change to another HD channel? If you answer 'yes' to either of these, it is most likely due to the television's processing capabilities. Because of the high amount of data that is required to deliver HD content, manufacturers have found creative (but not necessarily convenient) ways of dealing with the processing issues (blank screen delay for example). Since the audio and video signals for any given television station (either HD or regular) are transmitted separately, the television has to process that data internally so that you get the picture and sound aligned properly when you are watching it. HD broadcasts are much more demanding than regular stations requiring manufacturers to constantly improve this processing speed with every new model. On some televisions, the channel remains blank for a few seconds to allow the television to configure all of the information so it looks good when it's ready, which could explain the delay you are describing. At the time your television was manufactured, this may have been the best technology your manufacturer had to offer. On my personal flat panel, I get the picture and sound right away, but I have to wait about 15 seconds for the sound to catch up to the picture which I think is more annoying than being forced to look at a blank screen. But that's just me.

Hope this information was helpful.

Permanent blue haze on screen; looks like


The fact that you continue to have sound while the picture disappears points to one of three potential issues.

Issue 1: the LCD Panel.

Issue 2: The Inverter Power Boards (though these tend to cause power/shutdown/no video at startup than video distortion)

Issue 3: the Time Control Board - a small board at the top of the LCD panel on the back that relays data to the rest of the screen.

Any one of these three repairs, you should call Sony if the unit is outside of manufacturer's warranty. They are expensive to perform, and the parts are not cheap. Hopefully you have an extended warranty to help with the issue.

Press right side button or Vol+ and Mode will be highlighted
Press right button or Vol+ until it says Off on the right hand side of the Menu
Press exit and that should do it.

Hope this helps.

Black menu-like box randomly appears, covering the picture


This is a problem with closed-captioning. What you are seeing is a closed captioning box with no captioning in it. Usually this is being accidentally transmitted by the cable company "head end". Just make sure your closed captioning function is completely turned off. if you are seeing it randomly, it may well be coming from your cable company. Is it just on certain channels?

Intermittent loss of picture


You'll have to locate the vertical output IC which should be mounted onto a heatsink, then take out a good magnifier under the printed circuit board and examine the solder connections on the pins of that IC and resolder the ones that are cracked.
