Question about Proscan PS60690 60" Rear Projection Television

1 Answer

I have sound but no picture!

I recently acquired a PS60690 and the screen no longer works. I turn it on and there is sound, but no picture at all. I'm trying to figure out if it's the picture tubes or something else.

Usually a loss of picture problem on this set is caused by parts on the circuit board failing. Most often a repairman will find the problem around regulator in power supply or around main output transistor in horizontal circuit. Either way, solder work and test equip. are required.

Hi, I recently acquired a WD-52525 for free from a garage sale. The woman told me they just recently replaced the bulb but it no longer turns on (was working up until 2 months ago apparently). When I got...


If the TV's are noted for bad caps, and the description of the error makes that possible, the only fix is to remove all bad capacitors from the boards and replace them with new ones.The bad ones are easy to spot because they usually are either bulged at the top or have goop running out of them, or both.

Sound no picture


If you replaced TV lamp recently then check lamp cover and make sure to seat it properly.
Need further info, let me know.

No volume


On the back of your set there are 2 switches that tell the tv whether you are using the internal speakers or the external speakers.
Make sure the switches are set to internal so the speakers in the TV receive the sound signals. If they're set to internal maybe the internal speakers are bad. Set the switches to external and hook up external speakers to the speaker terminals on the back of the TV. If neither setup works then it sounds like an output transistor or related parts.

No picture just sound


Your projection tubes are messed up. It's a very expensive fix, just get a working TV off craigslist with a smashed screen and reuse your screen itself (usually 100-200$) or just toss the TV and upgrade to an LCD

Tv won't turn on


Usually this problem is caused by part failure on circuit board. Most often in power supply or deflection circuit. You will need test equip. and soldering/desoldering tools to fix this set. Most repair services charge 275.00-475.00 to do this repair on a PS60690. Crate is removable by removing rear cover, disconnecting spk. plugs and keyboard plug. Loosen two screws and whole thing slides out. This can save you service call fee.

Proscan PS60690 1st turns off then on by itself. Then 3 on-off cy I've had this exact problem twice. The 1st time I replaced the RCA part number 205064, which I believe is called the HV splitter. I used a generic non RCA part. The TV worked great for several months but went out again and it has been broken for 2 years. I finally ordered the new true RCA part number 205064 HV splitter. The TV, again seemed to be fixed, and what I a beautiful picture it had through our cable box. But, no happy ending at this point. It worked for a couple of days and then turned off and back on while my wife was watching it a few minutyes ago. It cycled off then back on twice in a 3 minute period so with the picture showing and tv still on she went ahead and turned it off. This is how the problem began several years ago the 1st time it went out. I don't want to turn it back on anymore in case the brand new HV Splitter is still OK. Does anyone know what other parts may be going out, causing the HV splitters to go bad and start shorting out. I know the HV spitters have been an ongoing problem with these sets, but since I just put a brand new RCA one in only 2 days ago I'm wondering if something else goes out first and causes the splitter to go bad after a period of time. I would appreciate any help. I can't afford a new set right now and the picture looks so great on this set using a cable box I feel it's definately worth fixing. ps Could missing o-rings cause this? I've never seen the o-rings. Even the first time I replaced the HV Splitter. Thanks
