RCA M32110 Hello, Trying to find where I can purchase a new circuit board for a RCA mm32110 It's the board on the top of the tv which has the power on/off Volume up/down and has the IR receiver attached to the board. The part #'s I can find on the board are (xx15568-730) ( rwb55300493) (15472668) The buttons work fine the IR Receiver part does not seem to work . Even with a new remote designed for this tv. I would solder in a new IR Receiver, But I'm not sure of the specs on it. Looks like a Vishay tsop312 series Thanks in advance [email protected]

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Hello,
You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where,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. Hoping this will help in solving the problem...

Most likely the TV has a power supply related problem. Or, it maybe something simple like a blown fuse inside the TV.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

Ok. PCB means Printed Circuit Board.
It looks similar to the picture down below. A part must have gone bad on your PC board. So, the RCA shop ordered a replacement PC board to fix the problem. It's an interchangeable part. All newer TV now have PC boards, which each one hold a different function.

try pts electronics, just go to search engine and type board number and it will tell where yoiu can buy it . at least 250.00
though.

bc

change antenna input to on air or antenna

check to see if your remont control dont have the mute button blocked down

need more info but it sound to be a cold solder problem,look at the circuit board closely for cracked solder joints. Resoldering any bad joints might just solve your problems, but be carefull there are very dangerous site inside a tv, if you dont know about tvs look for profecional assistances..good luck

Nothing special about that board as I cant seem to find that # but If my memory serves me correctly it sounds like a crt board and its a simple soldering job on the crt socket?? Altough Im not there to see the set still 550.00 seems like an awfull lot to repair a set even if they have to replace the entire chassis. I think you should cal rca and take it to an authorized RCA repair center and if the shop you took it to was an rca authorized center I would also report that to them(RCA). Good Luck
