Question about Televison & Video
I have a digistar tv, shut off on its own last night, no indication light. This means no protection mode or lockout or whatever it isn't getting power. So I went straight to the power board which is an AD151M24-3N1. Checked the fuse, it shows continuity so its fine. I saw on another question a guy asking about capacitance and voltage values of capacitors C12,C16,C89,C90. Not sure of the relevance of these since I don't have a schematic but any help would be appreciated.

No sir it probably isent a power supply problem as in these sets it wouldnt act like that. First thingm to check since you say your a service tech, is in the horizontal output check and see if the horiz. output transistors shorted. If its not then check a small coil off the base of the horizontal output transistor. its really the base drive coil so take it out and scrap off the ends BOTH ENDS and reinsert and also resolder the horizontal driver transformer. This may or may not fix your problem But if it dosent order if you think ther sets wrth it the flyback transformer as this is a big problem in these sets if the for mentioned things did do the trick. follow the kit instructions that come with the flyback transformer!! Dont take any short cuts. Make sure you do take out the horizontal output transitor or at least unsolder all the leads when tesating it for a short. Good luck

Please visit the following link. You will need to enter specific information on the model of your remote and your television. Hope this helps!

Norcent, Liteon and Digistar are all pretty offbeat brands, so if you're looking for a universal remote that has pre-programmed codes for all of those devices you're likely to come up short.
Both your URC-9911 and the much superior 15-1994 are JP1 remotes, which means you could easily program both of them to work all of your devices using JP1.
The URC-9911 is also upgradeable, so you also have the option of sending it back to OFA to have them add the codes that you need. In the event that they don't have a code for any of your devices, they would ask that you let them also borrow your original remote(s) so they can capture the signals and create codes for you.

Sorry, I am not famillar with your model, however most flat panel problems with start up can be traced to the power supply as the capacitors can fail due to the high operating temperatures. An electrical surge can also come in through the Cable and or antenna connection as well.

Speaker Relay Output Switch was a common problem with most SX models of the 70's. It's the switch you hear click on after about 4 seconds of power switch being turned on. It's still avail. thru Pioneer parts for around $45.
