Question about RCA BLC524 5.6 in. Television

1 Answer

Dead looking to identify U4 on power supply board. Mine is smoked. I can see 358 on it, that's about it. RCA or IC number would be great. Or the whole board if someone has a scrapped one. Thank you (one of the high speed switching diodes on this board was also shorted)

    thank you, RCA doesn't recognize that as a good number. Hmmmm? And it is labeled U4 right on the board next to the IC, so not sure where the IC501 comes in. I'll do a little more digging. What would really be helpful is if I could read the numbers on the IC.
    Thanks for your help.

    oops, I meant IC502 in my comments.......... ;)

    I still haven't been able to identify U4 on the power supply board. RCA wasn't much help either. If anyone would have occasion to look at that board and IC (U4) it would sure be much appreciated. Or point me in the direction of a junk/used set.
    Thank you

    FYI, it was a upc358 op amp. Along with the photo coupler and high speed rectifier and 300 ohm sm resistor, solved the problem.

I called RCA today and they identify this part as IC 502 and the part number they gave me is 244662-U4(stock number),the phone number you need to call for parts is 1-800-338-0376,in this number they should give you price and availabity.I hope you can relate to the information.

Tv takes a few trys to turn on and after a while it might or might not turn on. if it does turn on it will only stay on for 30 min to an hour and then it will shut of again and start the cycle again.


Hello,
It's the problem of overheating in the power supply board of the TV.on the power supply board of the tv there are few capacitors and IC.any of this ic is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.If otherwise power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
I hope this will help to solve the problem....

LG 42lc2d found u502 in power supply blown up.


You won't find a part number for this ic. These boards were made to be replaced as one piece. A new board should do the trick. If you can try to check for a short to ground. Most of the plugs on the board have voltages labeled. If there is a dead short you will see it with an ohm meter.

Picture problem


If this is a ctc 195 chassis then your likely problem is the convergence power supply that is mounted above the main board and the dynamic convergence board. On the board is an IC (usually) that can be changed: STK 730-010 I believe is the correct number...you can check the number, If it has a single transistor on the metal heat sink, I would suggest changing the whole board. Has only two plugs: one on each end of the board.

Remove the back cover. The switch mode power supply board is in the middle at the top. It's a large board. Along the top edge of the board the model number will be printed. It should be a bn96 00249a but check to be sure before ordering one. Take special note of the 5 fan headers located on the lower left of the board - all unused. Explains why so many of them have failed. Mine has been dead for almost a year now. I know which part on the board is bad, but so far, have not been able to locate a place that will sell me the IC. I'm not paying $300.00 for the whole board when all it needs is a $15.00 IC.
