When you turn the TV off do you see abreif white line acroos the screen and do you feel the static on the fornt of the set when it comes on? If so
This is an easy repair if you've ever soldered and would not be too costly for a repair shop to do it for you. The problem is a bad Vertical Output IC (usually mounted on an aluminum heat sink with the part on it labeled LA78?? ) and 1 or 2 bad capacitors. Some times you can even fix the problem by re-soldering the contacts of the IC- To find the IC follow the 4 wires that come from the Yoke (which is a contained coil of wires slipped over the neck of the picture tube(s)) back to the board. 2 of the wires go to the horizontal o/p and 2 to the Vertical o/p the thinner gauge wires are for the vertical.

Dropped 32 in Sanyo TV off of stand. It worked for 2 weeks and then the picture went out. Still have audio. What would a picture tube cost?


HELLO

A new tube will cost you the same or even MORE than a new TV. You could try to locate a second-hand tube but even then you would have to get a service engineer to replace it for you.

If I were you, I would just get a decent second-hand TV.

Hope this helps (:-)

Most likely there is a failure in the the scan amplifiers and or he power supply area. This will take some troubleshooting with a DVM and a scope as necessary. You will need the service manuals (schematics), and the necessary training and skills to follow up.

I think you should either look for another used set, or take the set in for an estimate. For someone who is not trained and equipped in TV service, this will be a big undertaking. There are also serious safety issues when trying to fix your own TV set. AS innocent as it looks, there are some high voltages employed.

Sanyo makes a fine TV. You have a problem in the vertical circuit causing the line. You should not play the set in that condition because you can dammage the picture tube. Call a few local shops to get an idea of what they charge to fix a vertical problem on a 20" TV. If the cost of repair exceeds about 65% of replacement, toss it. In my opinion the newer sets are lacking in quality compared to older ones. In short , they break more often. If you choose to buy a new TV stay with a known Japanese brand.

No picture on tv


probably you need to replace the picture tube or maybe theres a loosed connection in the high voltage circuit or the video circuit due to the fall. if the picture tube is the problem, you better buy a new tv coz replacing it is not practical and economical. but if it is only loosed connection just bring it to a qualified technician for sure he will not charge you too much for this problem. good luck!
