Question about RCA P61940 61" Rear Projection Television

1 Answer

My RCA Rear Projection TV Has Sound but no picture.

I just got this tv and when turned on it buzzed and they said to replace the HV Splitter Block. So I got a New HV Splitter and installed it. Now when you turn on the TV you hear sound but the tubes won't come on. They do however have a very dim light at the bottom of them Its a very faint light like it is warming up. I have left it on for at least fiffteen minutes and still doesn't come on. The model number on it is P60752EB it was manufactured in 1996. Any help would be very much appreciatted. Thanks Jehremy

The tiny lites you see on the end of the tubes or crts are the filiments. This is a normal thing and if you didnt see those I WOULD BE WORRIED.. Now Who is they ?? who told you all that was wrong with the tv was the HI voltage block?? if your not a tech Dude your traveling into some very ,very dangerous territory!! Do you know I used to know three differant peeps who wanted to fix there own projection tvs BUT they are now all DEAD!!! They all electrocuted themselfs fooling around with the HI voltage circuit same as you did!!! Man You should stop and think what your doing before you treally hurt yourself.. Now for myour problem. How do you know the HI- voltage block was bad??? It wasent if you have the same problem that you started with. You probably have a bad flyback or hi voltage transformer?? Well any who I hope you dont get hurt tinkering with these sets as you can if your not carefull!!! CALL A PRO to assit you. Lifes not worth saving a few bucks for is it?? Good luck

RCA 60" rear projection TV is Broken

If no arc into a bottle with the HV wire removed and inserted the trouble is before that. Set is prone to some nasty problems---a number (about 12) similar large diodes fail all over the set---have to check the voltages to know as they will test ok even with a diode tester.

Make sure you removed the right wire---ALSO VERY COMMON is when any of the HV wires into the block are inserted they bend over and will work for a while but sooner or later cause issues---you would be able to see this if disconnect the block and remove each red wire---they slide down and plug in---find one or more folded over inside the tubes and you have found your problem.

The Block is now very cheap --seen them for 20 dollars.

Look to the wires first!

Tv won turn on

This could be caused by a bad HV block. I would not take on replacing unless you know your way around HV circuits on Projection TV's. I would call a repair facility to give you a estimate to repair.

Power supply sparks when tv is turned on

That can either be the Flyback or the HV splitter. The flyback is located on the lower left hand side when looking in the rear and has a large red cable coming out of its top. The HV splitter is located in the front in the center of the set. These are both very easy and inexspensive to replace. I can post a link where you can get replacements with instructions.If you would like.

My RCA Bigscreen HDTV will not turn on.

Thats either the flyback or the HV splitter. If the sound is coming from the rear left side its the flyback. If its coming from the front of the set its the HV splitter. They are both easy to replace. I will post a link where you can get replacements with instructions if you would like.

I have a rca p52939 that won't turn on.

Failure of the HV splitter was a very common problem when I was doing these big screens on the road. The set won't come on if the splitter shorts. We used to test if that was the cause by pulling the HV input lead out of the splitter (leaving it still inside the plastic cup so it wouldn't arc anywhere) and turning the set on. Most often the set would fire right up (without picture of course).

I believe the RCA part number for the splitter is 205064, and it's available from a number of sources. I'm not home right now so I can't check. If I have the number wrong I'll post a follow-up comment.

Projection tv not working

I guess loud sizzling was from High Voltage Splitter in your TV. HV seems cracked and leaking high voltage.

You can observe and confirm it by removing back cover and power up TV from distance and check at rear of TV. Please take care and there should be little dark to observe arc from HV splitter.

If this is the case, HV splitter available in Part Store.

Disconnect the lead from the flyback to the splitter. Place the flyback lead securely in a dry glass container and try to power up the set. If it doesnt shutdown the HV Block (splitter) is bad.

Yes it does sound like the flyback is bad, the only other thing that arc is a picture tube.

The T.V. has no lamp, it has 3 guns red,blue,& green. Unplug the lead that goes to the high voltage splitter(make sure t.v. is unplug). Then turn the t.v. back on if you hear the H.V. lead making a hissing sound continuously most likely the h.v. block needs to be replaced. Follow the lead from the flyback to the h.v. splitter, this will be the lead that unplugs at the splitter.
