I have a PROSCAN Model PS52650, Chassis PTK188AB, Service NO P552690LX1. We had the transformer burn up and had it replaced. $161.00 Now the TV is cutting off and on all the time. The transformer used was not an original but aftermarket. It stays on for 6 mins before it starts up. Sometimes it goes another 30 before shutting off. I have the back off and a fan blowing on it and it doesn't help. Everyone says it will cost at least $400 to fix it and we should just throw it away and get a new one. Problem being I can't get a 48 in TV for $400 or $500. Any suggestions on what I can do(not a repairman). I am a Certified Microsoft Technician for computers so I know a little about electronics but not TVS

The PS50700 uses the 195 series chassis. The most common cause of the set not starting up is a shorted flyback (high voltage) transformer. Sometimes a shorted flyback will also cause the horizontal output transistor to short too. These parts need to be tested and/or replaced by a tech familiar with the RCA 195 chassis.
If you hear it trying to start up (usualy you'll hear a slight hiss about 3times) than the problem is likely the High Voltage block - a very common fault with these sets- The block costs between $40-$100 and because Highvoltage is present should be replaced by an experienced technician. If you decide to do yourself let me know.
HELLO. it sounds like it could be a couple of things why your set will not come on. 1. you could have a blown fuse.on the chassis. 2. you could have a bad power supplly transformer. 3. you could have a bad horizontal output transistor and a bad fly back transformer. it could be one of them or both of them as well as a blown fuse. because the fuse is blown from the horizontal output transistor burning out or the fly back transformer burning up. check and see if you have a burnt fuse, the size iof the fuse will be 5 amp to 6.3 amp fuse on the chassis right inside where the 110 ac cord comes in and hooks to the chassis. the fuse should be right there, look for it. hope this helps you"GOOD LUCK"
If you have no electronic experience and do not know how to troubleshoot electronics, then yes pleaqse call in a pro to assist you with this repair.. It hard to tell whats wrong with a set that is in a dead condition. It could run you anywhere from 50 bucks all the way up to 1200 depending on if a main board has to be replaced. Good Luck
