I have a 52in RCA model #P52754AT serial # 549390154 and chassis # PTK178LB I turn the TV on and the light flashes 3 times and doesnt turn on. I found a few diode's that look bad. what else you think could be the problem? thank you for your time you can email me the info if you want at email@example.com
I have the same problem as stang03 has described. My tv is a RCA 52" Model #R52WH74/serial#G303CNOIS with Chassis # ITC222A. Looks like RCA has problems with all of these tv's and isnt doing anything about it. I bought this tv at WalMart December 2006 and it lasted 2 years and 2 months. I was told by RCA customer svc this was an isolated case. Obviously NOT!!!

Hi, Not sure why chat got closed/ disconnected. There is big transistor TL010 attached with heat sink near flyback transformer, this is horizontal output transistor, check it and replace if found shorted. Thanks.
Deflection board , its bottom board to the left has FBT flyback transfomer CK capacitors cp 150 2200uf 16v use 25v and two more cp114 cp120 220uf 35v if cp 150 is puffed up on top it is bad replace All 3 capacitors for parts call Mats Electronics 1-800-628-1118, also For Deflection replacement board Call Encompass Electronics Parts 1-800-638-3328
Flyback and or CP150 are the most likely two components to cause that symptom. If you need more info let me know and also post the chassis number off the rear tag as that model used both ITC and ATC chassis numbers.
This is a common problem with this TV set as it uses the ITC222 chassis. The problem is usually localized to a group of capacitors CP120, CP140, and CP150. If you have a background in electronics I can send you the schematics and you can unsolder them and replace them using the schematic to get the values from. If you do not have a background in electronics, I would suggest you have a qualified Television Technician do the replacement for you.
Good way to test for bad buttons is go inside the back and there is a black multi-wire cable that is connected "front and center" of the center lens on top of the chassis....easy to get to from the back.
I've had touchy switches on this unit that cause the problems you're seeing....and who uses the switches? Your remote will still function, and with the buttons disconnected, the microprocessor won't get stuck servicing a false command....which by the way makes it IGNORE the remote when they go goofy on you.....
