Re: powering off

If you have convergence problem replace FL231 400ma in front of flyback.

Rca projection televisions HD52W68YX39 CONVERSION CHIP

This set does not use a convergence chip. All discrete parts.

Two things to check--Is the convergence option still seen in the menu?

If not there is a kit for that with 3 parts to change. And if convergence was going in and out before this---the set is prone to bad solder connections under the high voltage transformer where the 3 part kit is located also.

The board with the transformer is would have to be removed to look for the bad connections.

Transformer is also called a Flyback.

My tv shut off and wont come back on all it does is beep what is the problem

Hmmmmm. at the easiest point i would certainly find a bad capacitor or two. Alwasy suspect a 160 volt to 200 volt cap at 1Mf, 2.2Mf or 4.7Mf. Another suspect would be the 200 volt 100Mf caps that are somtimes used in theses TV. You do have a problem in the the horizontal section. Start with the capacitor check and check for bad grounds. It is the board that contains the high voltage transformer [flyback]. It is this board that will be reworked. Ask a tech, you have some knowledge of the problem and this will keep your cost of repair in your favor. Your proscan TV is a sister model of the well brand known brand, RCA! Hope this helps and thanks for asking!

Cannot Find Flyback Transformer 60PP9202/17F

Contact Philips directly. They should be able to get you the part, even if they have to get it from another repair shops. Many repair shops purchase their parts from factory authorized distributors, not from the manufacturer. The flyback transformer powers the tube-it can be extremely dangerous to work on-EVEN with the tv off, they contain a lot of power somethjing like 50,000 to 150,00 volts. It is not fun getting shocked by one of these as many techs have been knocked unconcious by them. If you do not know the proper procedure to discharge a flyback then leave it alone!

2003 d52w19, does it have a reset? It powers up and some sound, no picture then shuts down

These units are bad about loose connections around the flyback transformer and bad capacitors in the power supply. This is a dangerous circuit to work in so have a repair shop check it out for you. Thanks

I read the other post you made and I don't belive that the flyback transformer has gone , and these models and makes from rca do have some common fixes that are found out by tech's . this problem that you are having can be in the power section , stanby circuit , protection circuit or even a horizontal output IC or some component that is causing the set not to come on . the flyback transformer would need to be tested to determine if it went bad but the power section would need to be tested first because there are different voltages that come out of the primary transformer and they go to different parts of the tv's functions and circuits , also info like what happen when it went out? and or was there a problem with it while watching it before it went out? , this can help to know what section was failing , thus start the testing in that section.
the best thing to do is to call an electronic repair shop to have a teck come out so they can determine the failure for you , as these are pretty complex sets and unsoldering and soldering , testing of and value idenentification of components is required , so if you cannot perform these then you could be putting alot of money into it and never finding the problem.
if you would like any more info , I'll bee glad to assist you

Panasonic plasma th-42px25 turns itself off after 45 sec. and starts blinking power led light

The condition of your TV called power supply overcurrent shutdown. The TV is going into a protection mode to prevent further circuit damage. That's why it will not turn on or not powering up. I would concentrate on the power supply section board. Bad regulation of the incoming voltage could caused this issue although,there is a capacitor across the incoming line and nuetral.Maybe its leak or dry up and cause the problems,change it out with one of identical rating .I would probably also check the flyback circuit and flyback transformer although now you are getting into dangerous area,especially if you have no electronic experience background. It could be also be a loose ,crack or cold solder joint,a blown fuse,fusible links or other component .It could be one of several boards.Unfortunately the level of sophistication on these TV make it virtually impossible to diagnose them further without taking them apart and probing around with a multimeter and other tools.This TV is handy enough to take to a repair shop find a good one.You will probably have to pay $75 to $100....

Hope this may help you..

Tv wont come on

Most times when you hear this kind of sound on a TV it is because the flyback transformer is bad (from what I can remember anyway!). Its been a while since I repaired TV's, so hopefully someone can verify my info. The flyback transformer steps up the voltage very high which powers the color tubes. If that is bad, you will get the thunk sound. Also, if memory serves me well, there is a high power output chip that could be bad as well. Please, anyone who knows TV's, please verify for me. It has been years for me!
