Question about Sanyo DP26640 LCD TV
Picture is great. Sound is great. The set will freeze with vertcal lines the the screen goes black after a few seconds the screen picture will come back on as normal and operate for an hour or two then repeat the freeze and sometimes not come back on. I have used the set as a computor monitor and it does the same thing. HDMI 1 input does not work so I use hdmi 2 for tv input. Can I repair with new part or is this a repair shop job?
Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

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?

It sounds like you have a power supply problem, this powers the inverter! Where you just replaced the inverter, we could assume it is good! Look for some bad caps (capacitors) on the power supply board. They will look bulged on the top an may be a little leaky (brownish stain). The power supply can fail on some output and be good on others. Was the back light inverter new? If all else fails, see if you can return the back light inverter and get another! I hope this is helpful!!

SOURCE: Unable to use PS3 on HD channel
1. Connect PS3 to your TV
2. Select the Correct HDMI input on your TV
3. Press and hold the [power] button on the PS3
4. perform setup.
These are the steps to setup the video output for the PS3, It is possible that it is set to a resolution that your TV does not support.
If this doesn't work, you may want to contact Sanyo to ask if they have some protection circuit for the HDMI input. Some manufactures TV's will deactivate(turn OFF) the HDMI input under certain conditions. Unplugging the TV or some other procedure usually turns it back ON.

Sounds like a loose connection to the display panel. Did you physicaly move it from the time it didnt work to the time it started working..

Normally this problem is simply a matter of selecting the correct default audio playback device in the Windows control panel (sound option).
Check the Playback tab and set the default device to either DVI or HDMI.
