Question about RCA D52W20 52" Rear Projection HDTV-Ready Television

RCA 52130 won't turn on

TV clicks, but doesn't turn on, opened it up found a burn resistor at R14700.  I replaced the resistor, a 27k 1/2 watt, with a new one and same problem happened.  Do you know what is causing the burn out?  Got this tv from family and i'm not going to take a free tv to get repaired, i'd rather do it myself anyway. any help would be appreciated. thanks

    A schematic would be very helpful, i'm not very harware oriented, but i'm not paying for someone else to fix a free TV.
    Thanks

    Hello forallthsin,

    If you can tell me which board the resistor is on, I might be able to help. This RCA uses the Thompson ITC222 chassis, but the numbering schema might be different, know the board and what the resistor connects to will help in locating the possible cause. So I need the following information:

    1) The board the resistor is on

    2) what the resistor connects to (just follow the traces and give me what connects to both sides of the resistor)

    I do have the schematic for this chassis if you need it. (please reply if you need the diagrams)

    Thank you,

Check for bad connections on the flyback transformer

if they are bad you will see cracks in the solder

try resistor again

Convergence Resistors keep burning up


Some simple advice---if resistors are smoking one of the chips is shorted----The set has two voltages that go to them--one a positive voltage and one a negative voltage.

If either chip is shorted you can replace the resistors all year and not get anything. The resistors are protection in case one or both chips short----

Remove all old heat grease and install two new chips and replace the resistors at the same time.

Note that the set may have pico fuses on the power board also.

TV turns self off during watching, also has darkened picture.


Do a hard reset to the unit, unplug the unit for at least 2 hrs and then turn it back on it should work fine.

Smelled smoke and hot wires, tv went off and never came back on again. opened back and found only one small part looked burned out, ( broken and a little brown on the board.) Part number R14705.


Thats a 27K 1/2 watt Carbon Composition resistor 5% tolerance. You got deflection issues so a replacement resistor will most likely fail unless you discover whaich componenet on the deflection board caused the resistor to burn. The deflection boards have been discontinued for your model which has the ATC321 chassis. But you can get a remanufactured ATC321 deflection board from www.tvrepairworld.com

Samsung pcl5414r power resistors and pico fuses??


Hi again and welcome back to FixYa,

Appreciate the direct "Ask Me'.

Based on your original post, only the STK ICs were replaced. Presumably 392-040, the surrounding resistors and pico fuses could very well have been affected as well. Depending on the board revision (pls confirm location numbering on the actual board), the resistors could be:
RZ104 -RZ106 - 270 Ohm 1/2watt
RZ133-RZ135 - 27K Ohm 1/16 watt
RZ136 & RZ138 - 3.3K Ohm 1/8 watt
RZ146 and RZ147 - 3.9 Ohm 2 watt
RZ148 and RZ149 - 150 Ohm 2 watt
while the pico fuses would look like the image below.

Good luck and Thank you for using FixYa.

From your description ..actually this is a common problem and no simpley replacing the resistor will not fix it. this chasis has a problem with what is called the high voltage splitter.. there was a number of these made with a defective splitter. RCA HAS ISSUED a service bulliteen for certain models and serial numbers. the board and the splitter is generally replaced. (I just worked on one of these 2 days ago and got and order in for the parts) ......just reread the tech bulliteen.. the spitter which develops a crack is rca part number 258512 the resistor or the part that burnt is resistor a common 27k 1/2 watt 10% carbon resistor

Dark picture


If you can find it inside the set you need to replace R14700. This is the location number written on one of the boards. It is a 27K resistor at 1/2 watt. There was a bulletin by RCA on this problem

Not working


hd52w-- check r14705 for an open (should be 12k @ 1/2 watt... res. will probably break as you check it with a meter. if bad change (splitter}!! check Hor. Output for a short (Q 14401 ) it wiLL be bad. i advise replacing high voltage Xformer also (T 14401 ) make sure you cut leads to the proper lengths((not too long))..
