Question about Philips 50P8341 50" Rear Projection Television

1 Answer

Won't turn on

When I try to turn on, the tv clicks, once in a while a small power sound. Nothing happens. After 1 minute it clicks and the power button starts flashing in sequences of 6. When the tv does come on, it works fine. Problem is becoming more persistant.

Hi. This is an all too often occurrence. The TV's manufactured in the earlt to mid 1990s relied on an inferior set of capacitors in the power supply and mainboard components. They should have lasted about 25 to 30 years, but most are only lasting 5 or 6. The cheap capacitors pop, like a small balloon, or an overheated radiator, the capacitors contain an electrolyte gel, and this gel swells when induced with a charge. The cheap capacitors can split down the sides, boil over, or even pop the top off of them. If you look at the circuitry, you will see them standing up like small buttons, most with 3 wires coming out of the bouuton of them. Look to see if they have exploded like a battery, if, not, then your entire power supply is likely at fault.

Thanks for using FixYa. You’ll need to reset the Projection TV and to reset it follow these steps—

1. Turn off the television and wait for 5 minutes.

2. After 5 minutes unplug the television power cord from the electrical outlet.

3. Let the television remain without power for more then 1 minute.

4. Plug the power cord back into the electrical outlet. If the television is plugged into a power surge protector, remove it from there and plug it directly into the wall outlet. Turn on the television. If the issue is resolved, then the problem is with the power surge protector and not the television.

If the issue is not resolved then this might have happened due to over-voltage. Please check the power supply unit for swollen/bulged capacitors and burnt wires/components on the power supply board of your TV. You should try and turn off the TV for 8-10 hours to reset it. Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in OFF condition. All this is only recommended if you have electrical expertise and know how to solder/re-solder components.

Please do accept the solution if the issue is resolved or else revert for further assistance.

RCA Scenium HD52W140 Won't power

This has happened to me twice. We had the warranty and thank God we did. The problem is in a $7 transistor and you probably need to call a repair shop. They worked on ours and it took about 20 minutes to replace the transistor. They take out the bad one and soder in the new one on the circut board inside the back of the tv. The total cost was nothing for us because of the warranty, but it came to $385 for labor and stuff. Again, this happened twice, one year to the date from one another. The repair guy finally installed a different brand of transistors and it's been fine since. He said that RCA makes some terrible transistors and he will not use them again. Try and get the repair person to use a non-rca brand transistor, because it will more than likely happen again if he don't.

I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.
