RCA Projection TV will not turn on

hello is sound like 1 of the capacitor or transistor have blown. the fuse is located in the power supply glass type if you have to replace the fuse make sure you use the same rated value. the value will be on the end of the fuse or on the fuse holder on the circuit board good luck

sounds like a bad flyback on the circut board (a common problem) part is around 70.00 but they will get you in labor

check the flyback on it

how the inverter checked out

Now I know the rest of the story: After I went to see the TV I was told it had happened after a storm the next day the set was dead. She had already recieved the insurance money. She said she did not want to spend much money on it as she obtained the set at a garage sale for 60 bucks 6 years ago. As I looked into the circuit board I noticed evidence of water damage and looking up the case and on top, yup, thats why she got it so cheap. I do think it is lightly damaged. As a grandmother of a close friend I didn't Intend to charge her but she gave me some bucks and the insides of the tv. I'm sure their isn't much time on it. If any one wants some parts on a 1993 RCA mod p46770ck (48" screen) contact me thru snailmail @ Whiskers, rr1bx57a zip 64632 Include your ph.# and I will call you. (I don't use the computer every day)

ok lets begin... shut off? ...is the set staying off. NO POwer at all.. does the set try to come on. does the set have a blinking led on front. have you tried unpluging then waiting 30 min then trying to turn it on again.. this set has a processor and when it detectect any fault will shut the set down

It sounds to me that you may have a cold solder joint ( loose connection on the board ). I suggest you remove the board ( or seek professional assistance ) and solder any loose connections that you may find. That may correct the problem. Good Luck.

If it is a "minor" convergence problem you can adjust it by going to the menu and scrolling to convergence and follow prompts A cross will appear when you have reached the correct place and you do the minor adjustments as it says. If picture is bowed you have major convergence problems.

A clue to what is wrong is by looking from the back (taking the back off) and looking to see if the three picture tubes have any yellow glow at the bottom of them where the three identical boards are located on each tube.. If you have no glow there you possibly have a resistor R4703 open. It is a 3.3 ohm resistor and feeds the voltage to the filaments in each tube where the glow is suppose to be. If you do have the glow the problem could be much more complicated. Another to check is to see if the menu comes up on the screen. You could possibly be in the wrong input mode, Check your input mode with the input button on the remote The number R4703 is a location number to identify where the resistor is. This is all I can tell you that would not require much more complicated procedures requiring a tv repairman to look at it. If you have an ohm meter you can check R4703 but it must be checked out of circuit. (or at least one leg loose) Hope this helps

i'd like to help.that model# looks familiar.but that chassis num you gave looks more like a serial num all my rca prints go buy chassis # is there anothe num like ctc197 exet or ptk19 doc
