Whats the model number? Let me know that as it may be as easy as replacing the power supply circuit board depending on the model number of your set.

You are describing a convergence issue. Rear projection CRT sets use THREE separate color 'guns' that need to be aimed properly every so often, sometimes every month, sometimes once every year, but usually when its moved. Convergence operations are typically a user serviceable function and the process can be started from the menu.  If you have tried doing the user convergence and it is still a bit off you will need to get it to a repair technician that can either fix the power supply or mechanically align the guns.  In my many years of TV experience, rear projection CRT's are typically discarded for two main reasons; either the power supply is causing convergence issues or the blue gun is dull or dead. Either way if you cannot perform a convergence yourself you are looking at $200+ in repair and parts. I would suggest finding a local television repair technician, not many left I know, and get a quote.

Set wont turn on, stand by lights blinks 9 times


Have the same thing happening with ours... we were told by a repairman that it needs a new D Board. He told us that if we could fix the TV for under $500 that it was worth it, if not (which of course, we can't when you add in labor cost) don't fix it. I like the TV but I can buy a brand new flat screen for that!
Good Luck

Power Supply part problem with a SD-P5795W


I wouldn't trust anything this repairman said reason well for one thing how could he (or anyone) tell everything else is "in perfect condition" when he couldn't "see" anything to tell what it looked like. He might be right about the power supply being bad But it could also be the high voltage "power supply" could have a short and that would cause the symptions you describe
But if you want to try the power supply your self you can call Pioneer and give them the model number and they should be able to get the information you need.

Protron PLTV37C 37-inch LCD TV Yellow light indicator on; no picture or sound. Is it repairable? I was told the company went out of business and no parts are available.


There is a history with the power supplies failing on these TVs if it fails to power up, nut it could also have a back light inverter board defective.
The LCD still repairable if you find a good TV technician that knows how to fix electronics devices to the component level.
Let me know if you need further assistance.

How to fix the video power supply for mit VS-4544 ?


Let me preface what I'm about to suggest with my own comments. I've been a TV Technician for more than 20 years. That said, you don't fix it without calling repairman or you wouldn't have posted here. In this unit there are common lytic caps that should be replaced without question. By location number and value they are: C979 2.2uf/200v C531 2.2uf/160v C551 2.2uf/160v C981 22uf/50v C402 47uf/35v Next it might be a good idea to ESR test other caps in the B+ line. ESR stands for (equivalent series resistance) It's a way of measuring the cap's effectiveness in a circuit. There are testers on the market for just under $200.00 for the backyard technician and they are a must. Check the set for ring cracked solder joints. The symptom of leaving it off for awhile and then being able to get a picture suggests that it could be ring cracked in one or more areas, usually areas of high heat. When all else fails there is calling the repairman. If you don't know how to find a reputable shop in your area I might suggest contacting NESDA (National Electronic Service Dealers Assn.) who can give you some reputable shop contacts in your area. Good Luck! Bill
