    can you narrow the problem down to one board and location within the set ?

  • jimmiecooper Oct 20, 2008

    I fail to mention that the set has no video at all because it will not power up. I feel like if a board # can be given it would help greatly with the scratching sound problem.

Hey Jim,

There would be a capacitor shaped like a black bottle on the board which needs to be replaced. The new tube you have installed seems to need more power then your current capacitor can provide. If this keeps on happening you may end up burning out the capacitor. get a new one with a higher power rating.

Hit me again if you need more info.

The capacitors in your television need to charge up when the unit is first turned on. You need to replace them if the noise gets much longer.

  • Excessive load or faulty power supply cycling on its overcurrent protection circuit.


  • High voltage shutdown, or some other system detecting an out of regulation condition.


  • A dried up main filter capacitor or other filter capacitor in the low voltage power supply that is producing an out-of-regulation condition until it warms up. A bad filter capacitor on the output of a series regulator may result in excessive voltage and subsequent shutdown.


  • A problem with the microcontroller, relay or its driver, or standby power supply

MY SAMSUNG TV MODEL PCJ522R IS MAKING A CLICKING SOUND AND THE POWER LIGHT IS ON BUT TV WONT COME ON


Issue with the light ballast trying to light your lamp and it can't. Either a bad lamp (90%) - could be cracked or imploded or a bad lamp starter (10%).

Good day!!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Whining noise on start up, lamp and TV shutting down


The TV tech isnt too familliar with RCA TVs. The color wheel is the most likely problem no where near 1000. Depending on the model number of your set you can get replacement color wheels at the following link.

RCA HD61LPW42 - no picture


I haven't worked on an RCA DLP but have on Samsung DLP, based on your description it sounds like the color wheel is bad. Take the back off and turn on TV make sure its not a fan making the noise ,but most likely its the "wheel" it is inside the light engine probably right next to where the lamp is plugged in. If the whine comes from this area definitely the wheel.

Loud squealing noise first 5 minutes after tv is turned on


Sounds like the color wheel. It's the only moving part in most DLP's and the bearings can go bad. If it manages to get up to speed the picture may look normal. One temporary solution may be to let it run a few minutes, then turn the set off for 10 minutes, then turn back on. When my color wheel was going bad that would often quieten it down. For the rest of the day, try to leave the set on, especially if you're only going to be away from the TV for short periods. You can turn off your cable or satellite box but leave the set on and you won't have to go through the hassle of trying to quieten down the color wheel until the next cold start. Of course the best solution is to replace the color wheel which even with a rebuilt unit won't be cheap if your warranty is expired.
