Find Capacitor C4127, this is a startup cap and will fail. Then check C4709, C4105[this one almost always goes bad] and C4404. These are good starting points. You will have to resolder the Tuner as it will coorupt your eeprom and can create a dead set. And inspect the pins a Regulater T4101 I beleive, for busted grounds. If this will not start the set you will need a new eeprom or the T4101 Regulator. The regulatore rarely goes bad in this TV!

    After replacing the capacitors mentioned and the Tuner reworked, [and this will have to be completed] and the TV will not come on, you will have to replace the eeprom PN#223957 and try to power the TV. If then it will not power up than the T4101 regulator is bad. Once again it is rare but occassionally the Regulator will go bad. It has been one of the most reliable power Regs made! In the long run you will have a TV with a long life ahead, money and time well spent. PS the Tuner resoldered is delicate work...be extra cautious or you may destroy your TV. Patience my friend!!!

RCA P60920BL wont power up makes clicking sound


This is a chassis PTK195 and acommon fault with these sets, that causes the symptom you describe, is the flyback transformer goes bad.
If you're at all familiar with electronic repair you could start checking there (and horizontal output transistor shorts). If not have an RCA approved warrany repairer give you an estimate/service call.
Note: the good thing about these sets is the chassis is very common and easily removed for service (without bringing in the whole set.) .
Usual cost to repair flyback/ dead set symptoms $200-$350.

RCA, CRT Projection TV, ITC222 chassis Faults - models D52W.., D40W.., D56W..,...


RCA, CRT Projection TV, ITC222 chassis Faults - models D52W.., D40W.., D56W.., D61W..
· Symptom: No Convergence, Picture is bowed and distorted, colors don’t align.
The Fuse for the convergence power supply has blown
You'll also notice that the convergence settings have disappeared from the on screen menu. The fuse likely blew because of a fault on the convergence board. If you've never done soldering or dismantled a TV before this is probably not the best place to start. The back cover needs to be removed and the fuse (see picture) identified, the deflection/power supply board needs to be unplugged (label or mark all connectors beforehand) and flipped over and the fuse checked/replaced. You need a soldering iron and solder ****** or solder wick and a multi-meter to check the fuse. If you want to tackle it yourself see attached image for reference or get a quote from a repair shop (approx $200-$300 Total) the convergence board may also need repair.



  • Symptom: Dead Set - TV Tries to Start or intermittent dead.

The set could be in shut down mode due to a fault detected in the power supply, vertical or horizontal deflection circuits.
The common problems with this chassis that will cause a dead set or intermittent dead set symptom are, bad power supply capacitors, bad flyback, bad HV cap in horizontal output circuit and cold solders (on opposite side of board) especially under the flyback area. To gain access to replace any of these parts the back cover needs to be removed and the deflection/power supply board needs to be unplugged (label or mark all connectors beforehand) and flipped over.
These are only the most common problems and it could be any number of other faults.
If you have electronic (TV) repair experience check the items mentioned (see picture), otherwise it's best to seek a qualified RCA tech for an estimate/service call.

· Symptom: Erratic operation of set – turns off by self, the volume or channel changes by self or on screen menu appears intermittently.

Switches on the front panel assembly (FPA) problem.
What happens with this model is the FPA switches (one or more) start to conduct just as if someone was pressing the buttons. This in effect locks up the system control or causes it to initiate erratic commands.
The way to determine if the FPA is bad is to remove it by unplugging from set. This requires front panel disassembly.
Note: The remote will still work with the FPA removed so the set can be tested.

Hope this helped, johnnydiode, Fixya.

RCA R52WH74 (ITC222A Chassis)


no the board that has the FL231 on is the ITC222 deflection board. The other board is above the chassis in a seperate frame that runs across the set the convergence power supply is the board on the left above the board where the fL231 is. Yes the ITC222 and ITC222A are the same chassis. As for the service manual that site should have the service manual under the thomson category as the ITC 222 chassis is actually a thomson chassis made for RCA.

No power/RCA ctc187cl


Check for 5 volts present at pins of EEPROM IC. ( 8 pin-center
front) = no 5 volts = Re-check power supply components such as AC in resistor 2.7 Ohm ?....Or 5 volts ok,then suspect EEPROM corrupted........part # 223957 ( install 8-pin socket,then re-plug in original, if that doesn't clear it, plug in
new part) Use pre-programmed after-market replacement,if you 
can get it.....Let me know....T.

RCA P52940 Television


The P52940 uses the CTC195 series main chassis. The most common reason for the set not to start up is a shorted flyback (high voltage) transformer. The set actually does try to start, but the computer immediately detects the extra current drawn by the shorted flyback and instantly shuts the set back off. The chassis should be checked and the flyback replaced by a qualified tech familiar with RCA projection TV's.

RCA Projection TV MM52110 Won't Power Up


Being able to read a schematic and understanding how a TV works are two different things. These chassis that RCA used in these sets can be somewhat complex to troubleshoot. I would geuess that unless the power light comes on at all then you have a dead power supply in the TV.

Tuner Trouble


You will have to order this through an authoized RCA dealer Its not old enough yet for general publications from RCA If you call Sherl at TEEVEE Supply at 1-866-207-9824 or sales@teeveesupply.com give them the CHASSIS number NOT the model and they will order you one. You should know my freind when dealing with RCA alsway go by a chassis number! Good Luck
