Sanyo HT30744 tv

Turned my tv on in the morning and had sound but no picture.  Have tried a variety of fixes to no avail.  My question:  Since repair would mean a service call (too heavy for me to move), around $60. plus travel, would diagnosis and repair be worth it?

    Since I only paid $450. for the set, I couldn't see tying it up for a couple weeks of repairs at some indeterminate cost. I just went to Best Buy and bought a new Samsung lcd.

You have to find out the cost of the repair itself to make a decision.

I am not familiar with this model. I can speculate from experience going by your description.

If it is a CRT set and there is no picture the fault may be with the high voltage section, or a scan failure. It is also possible that the CRT itself is in failure.

J'ai repare recemment une television comme la tienne. A l'allumage l'ecran etait noir et parfois apres plusieurs minutes, l'image arrivait. Quand elle voulait arriver bien sur. J'ai tout simplement refait des soudures et refait des pistes sur le CRT Board. Ca avait l'air beau pourtant. Mais depuis bientot plus d'un mois, pas de nouvelles de mon client. Ca a l'air de tenir quoi. J'ai donc refait des pîstes sur le CRT board, entre les pins Bleus Rouge et Verte du tube et les pieces electroniques qui y etaient ratachées. Pas évident de t'expliquer ca comme ca, mais au pire ecrit moi j'essaierai de te faire un dessin.

Model number DP50747 The tv just turned off by itself. When you turn it on there is no sound or picture just a black screen. Only had this tv about 1 year. Can you help me?


I had the same problem with my sanyo tv a couple weeks ago, I took it to the repair shop, turned out it was a bad diode. $60.00 later I could watch my tv. I don't know if this helps, but I strongly suggest taking it to a repair place rather than trying to fix it yourself.

Sanyo HT30744 Aspect Ratio Help


Do you still have the original remote? If so there is a button that says "Pix shape" that will change your aspect ratio for you. If you are watching something in HD it should say "full". If it is analog it will say "normal" in 4x3 format. If you want it stretch hit it till it says "zoom 1" or "zoom 2". If you don't have the original remote I am not sure how you would change it. You can find them on ebay if you need one. Hope this helps.

Green screen


Not really sure how much the tv weighs, but I know it is a bunch. I have 2 of these t.v.s. One I bought at Wal-mart and after about 6 months it started doing this green screen also. I would normally give the side of the tv a good wack and it would go back to normal for awhile. The other tv I bought from my neighbor who was moving for $25. The problem with this one was the "no picture but I have sound". If I wacked this one I could get the picture to come back on for a while, but it would go out again. Well just the other day I took the back off the "no picture" tv and was looking around. I noticed that the circuit board that is attached to the picture tube was loose. I pushed it back down on the tube and put it back together and the picture has been fine since. So I thought I would check the one with "green screen" issues and sure enough that circuit board was loose also. Pushed that one all the way back down and have not had any issues with that tv either. Hopefully that fixed my problem, I guess time will tell. Maybe it will fix yours also.

Sanyo remote control hdtv ht30744


You need the original factory remote control. Do a web search for Sanyo. Go to their tech support. They can advise you about how to order a new remote for your set.

Green screen


Open it up and check to see it the circuit board attached to the tube is seated all the way down. Both of mine were not attached that well so I pushed them back down and have not had any problems since.

Dark screen/picture.


This 30" flat screen TV set may have a problem in the high voltage circuit of the TV set. You may be able to adjust this by taking off the back of the TV set. Look for the block where the large red wire runs up to the top of the picture tube. On this block will be two controls. one will say screen and one will say focus. Try and slowly turn the control that says screen or S on it clockwise and see if you can make the picture brighter. Turn up the control till you just start to see faint lines in the picture, then back the control down till the lines go away. If the picture does not come up when you turn this up, and all you get is a blank screen, you will need to have this set repaired by a qualified repair person. Good Luck

On and off picture and color weak Sanyo HT30744


I had the same problem with my refurbished HT-30744 model and my mom's HT-32744 model. It was either try to fix it or buy a new one, so I figred had nothing to lose.

I removed the back cover, unseated the picture tube driver board from the neck of the picture tube (it just pulls off), put on a dab of di-electric grease on the connector on the card, reseated the card, removed and re-applied more grease, reseated the card and the picture has like new for 2 weeks now!

This was a very easy fix.
