I have a model # DYLT032B 32 inch t.v. and the picture on the screen keeps jumping. My cable repairman was out today and said that the problem was with my set. The picture and sound is excellent but each time when I turn it on, I can hardly see the picture clearly 'cause of the jumping and running of the picture.

Much cheaper to just replace it.

I think if it was me I would return for exchange, refund or repair.

i think its from the cables try to put them correctly ... i think u putted them not in the good place

Well it very well could be the three color tubes, or power board the problem. BUT before you try that check your HDMI cable. HDMI cables have to be 100% in to fully work sometimes if out just a bit they will produce this issue where you have no picture but sound.
Or try a new HDMI cable, if you don't have HDMI and it's doing it on multiple ports including RCA, RF, HD Component then it's a problem with the tv itself and you'll need to call a repairman.

Hi, I am not sure on this one (as i'm based in the uk) but it sounds like your cable box (if its seperate to the tv) has gone into 4:3 screen mode if you can get into the menu of the cable box perhaps you can change the setting back to16:9 widescreen or perhaps there is a button on the remote control for changing the screen view.

If not perhaps theres a setting in the tv's picture menu where 4:3 mode is set instead of Auto or 16:9

Sorry I can't be of more help and hope this solves your issue.

You probably switched the TV from analogue to digital mode or vice-versa.

There should be a small button on your remote control marked DTV or ATV. Try pressing this.

If you are using a separate cable/satellite/tuner box from a SCART cable, turn off the tv, and turn off the cable/satellite box. Then turn the TV back on, then the cable/satellite box back on. The TV should recognise there is an external input and you should be OK.

Hello there...
Check its sleep settings. Someone may have hit the sleep timer and have set it to about 10 seconds. If that still doesn't help, please post a reply here.

If this jumping is accompanied by a sharp snapping sound, it may be the high voltage circuit discharging to chassis. Leakage can cause the jumping and a discharge can momentarily blank the picture.

If you want to try a 'cleaning cure,' I suggest you pull the plug (not just turn it off) for several hours, preferably overnight. Sets of this size can carry enough static charge to punch a hole through your thumb if you get careless.
Remove the rear housing (shouldn't be more than 6-8 screws) and using a clean paintbrush, and possibly a vacuum to **** up the dust, clean it well and pay special attention to the area around a largish misshapen black plastic object bigger than most anything else and connected to the back of the picture tube via a fairly thick cable.     

This should be repairable. It may be the LVDS Cable or the Main board problem. The only other problem is the T-Con Board.

i have the same problem which im guessing is the tv itself because i tried both hdmi ports with two cords and the composite cables but still same prob. so i have no idea what could be causing this
