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?

Hello, I just posted this to another user's question, and you might find it useful, too.

I have a pile of these in my shop. Unfortunately and usually, a backlight lamp is bad, and the inverter board is damaged when it goes out. The backlight lamps are sealed inside the panel, so the usual method of repair is to replace the panel.
If you turn the lights off in the room, then turn the tv on, you will probably see a momentary flash of light from the backlight trying to start up. The lamps can be replaced, but the option is not really cost effective given the amount of time it takes to replace them/very delicate nature of the lamps/availability of the lamps/cost of the lamps. Replacement panels might be available, but you'd have to use a TV shop for reference or call Sanyo directly.
These units also have a history of power supply heat damage, so if you don't see the momentary flash, it could be the power supply. But the momentary flash is the dead giveaway.

I hope this helps you...

Hi there! The panel may be in protection mode. The Inverter board is the most logical area to start after checking power supply Voltages.(5,6,24 and 13Volts). There may be coils on the Inverter Board which have bad soldering or faulty. Other than this it may be main board which controls switch on or off. If all else fails, refer to a repairer. Beware of High Current!!! Best Wishes and Good Luck, Jus004

The first thing I would check would be the electrolytic capacitors on the power supply board. If any of them are swollen or domed on top rather than flat, they will need to be replaced and that will fix your problem. I fix about 75% of them at the shop by replacing caps on power supply. A tech will probably charge around $100 if it is bad caps. It is a fairly easy job.

How to reset a samsung refrigerator model number rs261mdpn aftthea power outage


http://www.searspartsdirect.com/partsdirect/part-number/Samsung-Parts/Refrigerator-Parts/DA41-00669A/0046/401/Model-RS261MDPNXAA/1482/0165000


this is the control board you will need for your model if unplugging the unit for 5 minutes doesn't fix the problem. If they are LED lights, then I point my finger at this. This is a plug and play board with molex connectors. Very easy to install with unit unplugged. You can manually reset the display and check for error codes by holding the top left and top right button on your user interface for 5 seconds in unison FOR 5 or more seconds after all the lights flash.

Finding a used screen is looking for a needle in a hay stack. You will have better luck looking on Craig's list for the same model that isn't working. Replacement screens can be had...just google them and you'll be able to find one. Price may shock you and with shipping and installation costs it may be more than a new tv.

I need a manual with the progamming codes for a Sanyo tv


I don't have a code book for you, but I can tell you how to program the RCR660 using the automatic programming feature.

Programming RCA model RCR660 (no code search button)

While following these instructions, keep the following in mind:

device = the component you wish to control with your remote (TV, DVD, VCR, etc.)

DEVICE = the button labeled for the component you wish to program

1. Turn on the device you wish to program.
2. Turn off all other devices in the general vicinity.
2. Press and hold DEVICE
3. While holding DEVICE down, press ON/OFF and hold them both down until the LED turns on for that device.
4. Release both buttons.
5. Point the remote at the device, press and release PLAY and wait 5 seconds or until the LED stops flashing.
6. If the device does not turn off, then continue to press PLAY and wait the required interval (for a maximum of 20 times) until the device turns off.
7. When the device turns off, press REVERSE, wait two seconds and continue doing this until the device turns back on.
8. To finish programming, press and hold STOP until the LED turns off.
