If the set runs at all, your flyback and output transistor are good. If the set shuts down after a few seconds and the sides are wavy, it usually means that the main B+ in your power supply is too high and not regulating properly. I do not know what kind of power supply that model uses, but if has an old-style STR regulator (like the STR30130) then it is probably shorted, and if the set uses a switching power supply then look for an open or leaky electrolytic cap on the primary side. If the power supply is working correctly and the set shuts down, check for an open safety cap (the large 1.6 - 2Kv cap connected to the collector of the horizontal output transistor).

When u turn it on it has no picture or sound then there after it clicks on and off.

This is another typical issue with power supply boards. You need to have a qualified tech look at this and determine which board is bad, but it points to the power supply, they get the hottest and burn out the earliest.

The tv turned off 4 times in 3 or 4 mintes and will not turn on now .

Sally, You or hubby or boyfriend will need to investigate the internal "switch-mode-power-supply" because it may be going into "shutdown mode" because it has detected a "fault condition" with itself or another periferal electronic circuit. If not into DIY repair, I suggest contracting out the repair work. Before you do that, a visit to YOUTUBE will help. Search out similar or same size Sanyo model there and here at fixya for any history of typical "black screen of death" symptoms that may be the same as your unit. After your research is done return to this posting and provide us tech's more info and what you intend to do about your sanyo unit. 12fixlouie

INSTRUCTIONS NEEDED FOR THE SHARPER IMAGE - JUMBO UNIVERSAL REMOTE

Hello kls1996... programming your remote is rather easy. The easiest way (thanks to The Sharper Image Jumbo Remote being a LEARNING SMART remote) is to do the following:

1 - Point the head of your Sharper Image remote at the head of your Sanyo TV remote (nose to nose so the clear bulbs on each remote are facing each other).

2 - Press the "TV" button on your Sharper Image remote (located in the upper left-hand corner).

3 - Hold the "LEARN" button on your Sharper Image remote (located in the left edge under the volume buttons) until the red light flashes.

4 - Press the key on your Sharper Image remote (e.g. Volume Up or +VOL)... the red light will go solid (indicating that it is waiting for a signal from the other (in your case Sanyo) remote.

5 - Press the key on your other remote (in your case the Sanyo remote) that you want programmed in your new Sharper Image remote... the red light will flash rapidly again.

6 - Repeat step #4 until you have programmed each key.

7 - When done... press the "LEARN" key on your Sharper Image remote. Your Sharper Image remote should be programmed to operate your device (in this case, your Sanyo TV).

NOTE: You can program other devices such as your VCR, DVD, VHS, SAT, CABLE, etc. and not just one device.

Turn off 5-6 seconds after I turn on tv

Typical relay power problem on these sets for the relay power. most of the time, its the capacitor in the standby power supply that supplys the main 12 to 15 volts to the relay for the main power supply.. Problem is it is not a repair that can be done or understod by a layman in electronics. its a repair for an experienced tech as a TV set is not a place to be experimenting in.
