    I have the same issue on my RCA P46924 46 inch Tv. I have had no problem with this TV. it has lasted 8 years. Last night i turned it off like i always do before i go to bed, and then dismorning I was going to watch the news before i went to work BAM! NO POWER! What should I do? I did look at the Q14401 and it read as a short. I think the high voltage block is out. Where would i find parts for such an old RCA? Please help! This Tv is my best friend (Joking). It has even servived a divorce! Help me!

    I have to repair a similar RCA Home Theater TV Model (I have solely the drawer chassis but I will receive the cabinet sooner) P46729BA who has the same trouble but prior to repair, I want to know the difference between these service manuals prior do download. I need a P46729BA Service Manual but I have found 2 similar ones as P46729BADX1 and P46729BALG1. What is the difference between them? What these suffixes DX1-LG1 mean? It seams to be the same chassis? Did I can count on these service manuals to do it?



    Thanks in advance!

    Not the exact same model of TV, but I'm having the same problem. The AC bridge rectifier diodes (at least CR4002, but replaced 4001-4004 to be sure) blew after a drink falling off the top of the TV and getting into the back of it. I've replaced the diodes but it still doesn't turn on.

We have the same model TV and the same thing happened a few months ago, we could not turn it on. However, after playing with it a while, if you hold down the power button and then hit the channel up or down button repeatedly it should turn on, at least that how i have to turn mine on all the time now. Hope it helps.

Yes could be several problem, the first one in my mind is burt horzirontal transistors, Q14401 or bad hight voltage block.
Could be convergence problem that is causing the system to shout down.

Hope this helps

My RCA HDTV D52W23 Will not Turn On!!
Trying installing a new power supply. This is the main problem with tv's with the issue. But if you just bought it I would try to get my money back from where I bought it from. Installing a power supply for a tv is not that hard at all.

36 inch RCA 36v430t
Mike-It looks like the power supply is going on your tv-it can be replaced. This happens, usually, when little kids are playing wth the remote or power button on the tv. Turn it off and on a whole bunch of times in a row, kids love to do that, and it burns out the power supply part- to make a CRT tv like your RCA36 incher- which is a beautiful machine- I have the RCA/PROSCAN 36 incher-LAST longer...You should always wait 5 min between turning it off and on. Don't ever sell it. This one is worth fixing. It has better color and sound Than the new plasmas and lcds-The Pros know this. Be carefull, they might try and talk you out of it-so they can fix it and have it for themselves. So what if it's not High Deff. It's a great set.

Comcast Remote Control Code
comcast sucks and its tech support are a bunch of idiots. the book that comes with the remote is wrong (and for some reason no one in tech support knows this). the remote requires 5 digit codes and all the codes in the book are 4. typing the number 1 in front of any of the codes in the book, for any device and manufacturer, should fix this problem.

Tv not powering on
as per your statement there is a loose contact in power supply section of your tv. it is 1oo% sure that allthe parts are ok as tv runs ok when it comes on. but you will have to call tech. as without knowing technology it is dangerous to open tv due to high voltage.

This could cause a problem, because modern TVs and most other entertainment electronic goods, have a small kind of computer chip, but there should be a Reset button probably inside the set! If you feel confident about computer chips you may be able to find the button by tracing the circuit.(Disconnected from the mains). Another idea is if there is a small button cell or battery inside, then try disconnecting it for a day. Good Luck!
