Question about Proscan PS80690 TV

1 Answer

Will not power up with panelswitch or remote

I've joined your site and have searched for a way to post a new problem for "Proscan Rear Projection TV PS 80690 Chassis CTC188" and am unable to find the place to click for it perhaps I am Blind but it seems the only place i find Post problem is under a model already posted please help me thanks Jer My problem is similar to other models Was watching went into other room came back TV off Asked Wife if she shut it down she didn't tried to power it on and it seemed to try to power up LEDs on guns came on and off 3 times then off unplugged for an hour then tried again same result bypassed surge suppressor same result. Consulted service manual downloaded from net says if power requirements aren't met then this is the result. TV is ging on 12 but still had full bright picture with minor convergence issues in corners. So i'de like to attempt repairs as treplacing an 80 inch TV today is at expensive least, unless I go for front projection. I worked for a TV repairman for a couple of years when I was 16 (50 now) and replaced flybacks, coils, transistors, capacitors, resistors, etc. I have repaired many devices by redoing broken solder connections etc. but I have been repairing and building computers since '93 thief took my scope and signal gen. Still have electrinic VOM with cap and trans checker. So i'd like to get a hold of some sort of flow chart to trace the problem. Sams doesn't list this model, the books i've looked at are too general, and Thomson Projection TV Basic Service Data manual I downloadedfor ctc188 has none, checked HOT it's fine, tried powering up with less voltage 80vac no go cannot check voltages listed in service manual without power, it's not the fuse. please advise

    My ProScan PS80690 made little sound and turned off whole we were
    watching TV. I have tried all possible ways, including disconnecting
    power for 15 minutes to 24 hours and tried to turn it on with remote
    and by pushing ON switch on the unit. No response of any kind.

    We
    live in a small town and the closest service center is 100 miles. The
    service center says they can not get parts for this unit. RCA produced
    very limited number and don't produce spare parts any more.

    I will appreciate guidance. My e-mail address is [email protected]

We have lost the power cord to plug into our Proscan TV model: PS52652 chassis: PTK169PDBS. where can we find a cord to purchase?


Check with techs that repair these sets or any tech. If they cant find the right power cord they can allways take the power cord from another name brand set and wire it in.

My tv. proscan mod. ps50700 won`t turn on


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.

Hi there, you seem helpful, I have a Proscan PS61670 rear projection TV, I believe i need to replace the IC however in my service schematic it shows the "Digital Convergence IC" on the board as a STV2040T,...


Thats an obselete IC. Your model came with two chassis designs the CTC195 and the PTK195 could you verify which chassis your model has and I will try to cross refernce it to a substitute part number for you. Please respond to this same post when replying.

ProScan wont turn on


PS52690 52" projection TV (CTC188 series) that won't power up. From what I have read here and other places, the most common cause of this is the HV splitter. Actually, when the unit was 3 years old, the HV splitter went out and had to be replaced but it was under warranty at the time. I have found that the part I need is 205064 and runs around $40-$70
A post in another thread said that you could test to see if the HV splitter is really the problem by disconnecting the HV anode (big red wire) from the flyback (not the splitter since that will arc), plug the TV in, power it up, and if the power stays on and you hear sound, replace the HV splitter to fix the problem.
