good day.
The crt circuit of the unit might be loose or the the parts inside the board is loose. Have it hecked by a technician first. Minor parts inside might caused the problem.

Response is highly appreciated.

hiiiiiii here shivam
i want to tell you that that same problem is occuring my computer but now it is fixed
but your problem is of tv don't worry is this is help full to you--

this problem is common on this model. your vertical output circuit has gone bad. but i am sorry to say that a repair cost is to much for a tv this age. a cost would range 100-150. i say invest this into a newer tv. this model was good for 10-12 years and you have got better than that.
good luck :)
let me know if you need more info?

This could be 1 of a few things here. Without opening up your set and trying to look at voltages or indiciator lights I couldn't tell you exactly without some more info.

Without looking at it myself here are my thoughts and where I would first look at.

It may be a main board because:
1) Main board processes all your audio/video signals. Bad main board means bad video processing. Could do that. Especially if the main board is not sending the right signal or a bad signal to the rest of the boards so they don't do their jobs. 

It may be a power supply because:
1) Power supply is well, the power supply. If it's sending inadaquete voltage to the main board you may not be recieving enough juice to keep that main board doing your video processing or further up the line keeping enough juice flowing to your TCon board to keep it telling things where to go and what to do. The power supply sends voltages to your Ballast board(controls your lights) and to your main board through which power is supplied to your TCon board via a LVDS line and a +12/+16V signals. If the power supply isn't pumping out enough juice to keep the TCon or Main Board running, it could be a problem. By the same token it could be that your P/S isn't sending power out to your ballast board. 

It could be a TCon because:
1) If the TCon is bad, you won't get your pictures. This could be the TCon board itself or the LVDS cable from your TCon to your Main. However, with few exceptions, if it's a bad TCon you're looking at a total panel replacement. 

It could be a ballast board because:
1) The Ballast Board controls the lighting behind the LCD screen. If this isn't working right you won't be seeing much of anything without that back lighting. If this is bad, it's a panel replacement. These are not field replaceable items by LG. 

Based on the symptoms, without more data or a eyes-on view of it, I would say you're most likely looking at a Main Brd or PSU problem.

Sanyo DP26649 screen blacks out and sound becomes loud static


Most likely you will need to get a diagnoses performed on the set. Your problem could be with either the main board or power supply board. The million dollar question is do you repair or replace? With parts and labor to repair this set, you could come out cheaper replacing it.

Sirs: I have a new Sanyo 42" TV. We are on


Hello
If picture and sound is ok, and there is no colour, your push have sometimes made its system changed. I don't know from where you are, and to which country you belongs. Anyway I'll give you one solution.
Your Sanyo Tv may have multisystem compactable. There are mainly three systems in transmision of TV signals, called PAL [Phase Alternating Line], SECAM [Sequential colour and mamory] and NTSC [National Telivision System Committee]. Most of the europian countries have transmitters with SECAM and NTSC. I belongs to India, and here we have PAL BG system.

If the system has changed in the tv, the picture will not have chroma information, ie ,colour information, and black and white picture will be the result. You just do one thing. Just get into the Menu of your TV, according to its documantaion that you have, and go to the system menu, and make it "AUTO". This will solve your problem. Ok.
