this problem is caused by the interruption of the fuse .if you can replace it, you might solve the problem.(before removing the cover of the tv-set make sure you unplugged it.replace the fuse with an identical one,then plug-in the tv-set and turn it on).i hope that it will work.if no change contact the nearest repair shop.

no. the tv has to be built for hd. if you want to watch true hd you have to have an hdtv.

absolutely not. digital applies only to vhf/uhf signals.

if you can't operate the receiver from the front then there is something wrong with it. you need to get it repaired or replaced.

I e-mailed Sanyo, and their response is that this TV has an analog tuner so you will need a converter.

If you look at your remote there should be a small rectangular box (shape of a tv) with an arrow going through it. You can use this to flick through av1 av2 etc

TV's have a circuit that monitors the high voltage and shuts down the set if it senses something amiss.
Figure on replacing the flyback transformer.
However, my experiance is to not put money into a TV that is over ten years old. TVs stress out their electronic components worse than almost any other electronic product. After 10 years, there are so many parts that are ready to fail that your are probably wasting your money trying to get any more life out of it.
Another option is to wholesale replace the main board from an outfit like PTS Electronics at ptscorp.com.
Hope ya fix it!

did you try to connect your tv to another source in the house.if you have cable anywhere else. try to connect your tv to that cable.if that works you might have to buy a new cable for your tv.

deko, heres the number for Sanyo parts, 800-877-5032, you can order the service manual there, part number for manual is KTDS27425. I`m sorry I don`t have it to look up the IC but it will be very usefull to have the manual, I think it`s around $20.00
good luck with it, BMW Rider

What input did you connect the satalite to? Probably one of the 'video' inputs I'm guessing, which means you have to select that video source using the 'INPUT' button on your remote. (Some makers use different names but you get the idea)

Vertical sweep failure.
It will be an I.C. with a part number that probably starts with an LA_ _ _ _ and be on a heat sink in the vicinity of the connector going up to the yoke. Try replacing that. But first, check all the electrolytic caps around it for testing dry (sorry - takes a special meter to do it in circuit) or just replace them. May have lost power to the I.C. as well. Look the I.C. up in the free NTE crossreference at nteinc.com get a diagram of its pinout to find what pins the power and outputs are on.
Hope ya fix it!

How old is this TV?

Be careful on buying a new one though. Often times, these new technology ones are much worse. Always Google the model number of the set you intend to buy and add the word 'repair' or 'complaint' to see if it is one of the many models that are customer service nightmares being produced by even the most reputable companies today.

Hi,
If the picture is roaming as you say then check to see if you have 33 volts on one of the pins of the tuner. If not this will trace across almost the whole board to a resistor: some models will be 39k and other will be 27k. May be (don't remember exactly) R106. Anyway there will be 130 volts on one side and 0 on the other. This feeds the tuning voltage to the tuner 33 volts. I have seen it where the picture is not there at all and sometime I have seen it as you say sort of roaming off frequency. Hope this helps

Check Q605 for short. Hope this helps

Ours is doing the same thing except on Video 1. I called Sanyo customer service and they said I need the original remote. They were willing to sell me one for $20. Here is what I did instead. I used a cable box and hooked the cable in to it. Then I took the type of cables that will hook into my video 1 slot and plugged them in there and plugged them into the back of the cable box in the "cable out" positions. It worked ! If you do not have a cable box you might try a DVD/VCR combo or a VCR. Good Luck

it might be due to

• plug or socket loose where tv is connected.
• loose connection in switch.
• some connector loose in power supply
•  switching transistor in power supply &horizontal section loose or wire open
• some capacitor loose in oscilltor section in power supply.
• if you are not tech. person please take help.
• hope this will help
• good luck

if you want to much about remote please go to www.remotes.com you will get all answers.

You could have a power supply problem or a sweep supply problem. If you have had any TV repair experience, you will need to get a schematic and go from there. if you have not and still want to learn, Please read the article im posting for you. A tv set is not a place to be poking around in if your not sure where to poke. Good Luck http://www.techlore.com/article/15116/ Please do not forget to rate this thread.

what is the question please?

The only test you can do on this regulator is to see if is shorted or not,this is a switching regulator ,that means is design to be use in a switching power supply witch turns the transistor on and off constanly and uses feedback to stay regulated,the B+ they use in the collector is around 150 volts,an small square wave is applied to the base ,it gets amplifies and energizes the primary side of the transformer to generate all the supplies ,one of this supplies provides the feed back.I hope I have given you the more than the information you needed.
