Chassis will need to be pulled by a skilled technician.Some specific area hand-soldering is needed and the STK convergence IC's need changing w/OEM or better quality parts.You have a good set worthy of repair.

Soyo DYLM1988 vertical hold/jittering picture problems when starting up. Clears when warmed up & playing with monitor settings helps.

How old is the screen? if more than 5 years, the circuitry can go bad. I had this with one of mine, it would jitter for about 10 mins before it warmed up. Just get a new one, they are cheap as chips

When turned on picture was unstable (Jittering) for some time. Now when turned on the power indicator light comes on then blinks. No operation or display. I can't locate a repair for this unit in...

Depending on your Toshiba model this may be an issue with the hypermodule. When it fails it will make the TV zig zag looking. One quick test is to see if your picture-in-picture window looks normal. If so the hypermodule is the issue. You can google Z1234TV to locate parts.

Sony hdr-cx7 image jitters when the cam gets hot

one fix is turning off steadyshot then try putting the camcorder upright(the lens pointing up) for few second until you see the video stabilize, then use as normal but the camcorder will jitter again if handle it roughly. This is just a workaround, i still dont know why it happens, need to send it for repair soon.

Shaking

On the power supply PCB are two 220uf 25V capacitors that will be leaking. Replace both and the picture will return to normal.

Issues with the big screen

This is essentially a convergence problem and will continue to get worse. If you can solder, try resoldering the pins on the convergence ICs. If that fails to resolve the problem, replace the ICs. These are large black ICs attached to a heatsink and should be marked STKxxx.

Keep us posted on your progress.

Picture Jumps/flashes for first 5 minutes

There is a module called a hyper board that is vertically mounted near the jack panel. Inside the module are 10mf/25v capacitors they are grtting weak. The module is fully shielded and pluggs into a socket. the module has 4 tabs (2 on each end) that must be unsoldered before it can be unplugged. This repair should be done by a qualified technician. The caps are surface mounts and very small. Unless you have excellent soldering skills and a rock steady hand DO NOT ATTEMPT to repair this problem on your own.

Akai pdp 4273m 42

I cured the problem by placing a fan in front of the screen that not only blows directly on the LCD screen, but also air underneath the screen providing circulation around the entire unit. Apparently the LCD screen is overheating causing it to "trip". I can stop the blower after about 20 minutes and there is no problem.

I will never buy another Westinghouse product again as long as I live.

Toshiba 61h70 Picture Problems Hello, I have a Toshiba 61h70 TheaterView HD Projection TV, and was recently having some slight convergence issues (red was out of alignment and could not be adjusted). So I researched and found that the IC?s (STK392-110) needed to be replaced. I initially purchased them on eBay, to later find out that they were cheap clones and did not work (they made the convergence worse, actually). I then purchased 100% Sanyo IC?s from a reputable dealer and replaced the IC?s again. Once finished, I then entered the service menu and adjusted the convergence alignment. Once the alignment was perfect, I hooked back up the TV antenna, the DVD player (composite), and the S-video from my computer. The convergence is fine, but now I?m having a totally different issue ? the video is ?scrolling?. The menus will show up fine, however any incoming video inputs will show up okay for a split-second, but will then flash and the picture starts to scroll in different directions. This happens with any of the video inputs. I checked and changed all the service menu items to factory defaults, however this had no effect. I have pasted a link below to a short video that illustrates the issue that I?m having. Please note that the video starts off with a black screen, showing the ?input? menu, and then I selected the ?TV input? and changed the channels. You will see the picture fine for a moment when the channel is first changed, but then the picture will start to scroll. Any ideas of what would be causing this? And how can I correct the issue? I?m not a TV repair expert, so I?m not even sure where to start. Any help would be greatly appreciated. http://s75.photobucket.com/albums/i303/hybrydmike/?action=view₪t=TV_Troubles.flv
