20 Most Recent Sanyo DS24424 24" TV Questions & Answers

Just press the 'AV' button on the remote control to eliminate it.

Hi vfg1575,
This symptoms is commonly caused by mis-aligned sound IF transformer. Due to aging, frequency produced by the IF transformer vary and will affect the performance of the sound output. Sometimes the re-alignment will cure the symptoms just within a minute. You must have an IF alignment tools to perform the alignment procedure. You must turn it counterclockwise/clockwise (little turn only) while the tv is on to hear the sound output produced. You will notice that the sound strength will vary as you turn the IF. The IF transformer is labelled in the board as SIF. Here's the sample picture of it.


If the symptoms didn't cure by the IF alignment the fault came from the sound output circuitry which is caused by faulty coupling sound input electrolytic capacitor, poor solder joints, faulty sound output IC.
If you don't have necessary tools and test instrument and can't troubleshoot the symptoms yourself, I would advice you to look for an experienced technician to isolate the problem.
Note : If you are going to DIY, you must know safety precaution because any little mistake may hurt you and/or resulted in further damaged.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Hello
This fault can occur to mainly three reasons. ABL circuit failure. Low screen voltage or lack of emission from picture tube cathode. Just advance the screen voltage to a little, and observe the result. Screen control can be located on its Line Output Transformer [LOT]. there will be two variable controls built on to LOT marked as screen and focus. Screen control will be at lower side, and focus will bw on the top. Just advance [clockwise movemnt] to a little, not more, advance it till retrace lines are just visible on the screen. Before doing this, set all the picture controls, contrast, colour and brightness of the TV to zero. Once the retrace lines[thin horozontal white lines across the entire screen at about 1 inch distance with each other]; are visible, stop there, turn the screen control counterclockwise to just a point when these lines are just goes off. make this adjustment in a dark room so that you can set this point very correct. After this check the perfomance of the picture. If this does not help you, ABL circuit should be checked for any fault.
If emission of the picture tube has got down, even the screen adjustment said above won't help you. The only way is to replace the picture tube with same type and number. OK.

May be power supply failure and then maybe cold solder joints...a lot of sanyo's came in the shop that had bad solder joints...we would look for solder joints with a cracked looking ring around them , resolder them, and the set would usually work...you can try to remove the back to gain access to the underside of the board to see if this may be the case...otherwise, it may be a circuit malfunction

Try the on board menu on the tv to see if you can gain access, if not the original remote will be required. One possible solution is to go to a tv repair shop to see if they might have one. They usually keep a box of used remotes.

Hello
Your TVs focus voltage has some trouble. You gets an out of focus piture now. There may be two reasons for this fault. The first one is, the focus pack trouble. The second one is picture tube base socket trouble. Both are repairable.
Focus pack is integrated with Line Output Transformer [LOT], and picture tube base socket is soldered directly to picture tube base card. You just open the TV and check whether there is any "Shhhh" sound comes from the neck side of the picture tube while tv is working. If it is so, you will get a smell of Ozone gas also. If it is so, switch off the set and unplug it from mains socket, pull out picture tube base card from the picture tube neck. Be gentle, and not make any shakes while pulling it out. The neck part of the picture tube is very thin relative to its other portions of the picture tube, and have a chance to break. So be carefull when you pull it out. You can see the base socket soldered directly to it. There will be two wires also, for some sets only one, attached to it. Normally the red wire going to a slot in the socket is focus wire, through which focus voltage reaches to the relative pin of the picture tube. Just detach the wire out from the socket, desolder it out and go for a similar type, and pin confuguration. Replacing it will solve your problem. After replacing the picture tube socket, a slight focus adjustment may be needed. Sometimes may not. The focus voltage can be adjusted. Its adjustment control is located on the above said [LOT]. There will be two adjustment controls, marked Focus and Screen. Out of which the upper one is for focus adjustment, and the lower one is for screen adjustment as its markings states. You just adjust the focus control very little, while watching the picture on your tv screen. Take menu display for reference, rather than moving pictures for focus adjustment, so that you will get a stationary image for reference.
The second stated trouble is related to the screen-focus pack integrated with the [LOT] itself. If it has got damaged, there is no other way than replacing the [LOT]. If so desolder it out from the circuit board, after detaching the anode cap from the top of the picture tube,and focus and screen wires. Before detaching the anode cap, care must be taken, as there may be some extra high tension voltage charge on the final anode of the picture tube, which is dangerous. You must discharge it before unpluging it, otherwise you may get electric shock from it, even after the Tv is switched off and unpluged from the wall socket. The charge may retain there for hours. So be careful.
If you have any more doubts, inform me through Fixya. Ok.

ese tipo de televisor viene con mucha soldadura fria. trata de resoldar todas las resistencias y los reguladores si encuentras bien el fusible.el 90% de las veces es eso.

tienes el parental lock puesto, quitalo y se desbloquean los canales con contenido adulto.

could be the lamp our the ballast go to http://www.discount-merchant.com/

From what i can see you set is hdtv ready. If your search google you will find quite a bit of information on it. hope this help

Google this to find a supplier " 1.25 A GMA AGC fuse " They are commonly available at Radioshack (the Source)

I too.
My fuse is good, I took the plunge and removed the 6 screws around the cabinet and 1 in back by the Video In jacks, pulled it back 8" and checked. Then I went further and disconnected everything (careful with the TV HV Rubber capped tension lead - it can kill you! and I found some board discoloration (heat) and tshot some more and found a bad transistor in the HORIZ OUT section. Mine is a TT2168 and I am looking for a replacement part now.

Typically when these fail, it is because of excess voltage or excesss heat. It gets kicked thru a coil, which gets kicked from another chip. I will let you know what I find out.

It's in the remote control, try check the menu
