Hitachi ultravision digital projection TV. The picture scrambles horizontally. The colors look fine. The picture is great for the first few minutes the TV is on, then it scrambles. I've unplugged it,


This sounds like a heating problem..Either there is something keeping the heat inside the cabinet like stuff on top of the cooling vents (also on the sides and bottom) or there is dust inside. Blow the thing clean with clean, dry compressed air inside the cabinet.

Sylvania hdtv model lc320sl1 will turn on but does not get picture.... sound works.... various colored lines and or scrambled picture appears at best


Let me start at the beginning---Likely a bad main board in your case but nothing is sure in this type of set.

Main board controls all information to the front screen and communicates to various boards---There really is almost never a simple "that part is bad solution" as any board, the power supply, the main, etc can cause issues.

It can even be a issue with the front screen unit--called a display panel.

You might consider doing some research on the set by Google of the model number with "parts" to get an idea what is available and what potential parts cost might be.

If a main board is bad it will average from one to two hundred just for the part----if issue is the panel you are done--part if even available is more than set cost when new.

Let me know if you have questions.

I'm connected to a dish network receiver and the picture was good until my son tried to plug in his playstation 2. Now everything is back to the way it was originally installed except there is a scrambled...


Hey there. You want to make sure that the cables are tight on the back of the receiver and also that the tv is on the correct channel or input. Sometimes, if the tv is on the wrong input, you can get the picture, but it will look scrambled. So if you are in the room with the receiver box, you want to make sure that the tv is on channel 3 or 4, and sometimes on an input like Video 1 or 2. If on the secondary tv, you will want to make sure that the tv is on channel 60 or 73. I hope that this helps. You can follow this link below if you need more clarification.

It sounds like T-CON board problem, and possibly the main logic board. I would check first to make sure the T-CON board get good 12vdc feeding it first.

- Picture scrambled when set is


The TV has a bad board. It's called the Hyper board. It has been discontinued by Toshiba years ago so it is not an option to replace it. There are some TV repair shops that can rebuild this board by replacing most or all of the capacitors in it. You may want to call your local shop and see if they can do.
