We have a rca projection tv model P52929 heard a pop and tv went out now won't come back on. fuse was blown replaced it it says 5v125v it blew as soon as we plugged it in what could it be

Deflection board has issues most likley the flyack transformer or CL031 has fried. Replacing the deflection board will usually solve the issue. Replacement deflection boards are available from www.tvrepairworld.com

Although this is rare, the problem is the lamp driver board, commonly called the ballast board. Follow the leads back from the lamp an you will find a smallish rectangular board with one large connector and one small one (besides the two wires going to the lamp). If you feel confident, they can be ordered from a Sony parts distributor such as Vance Baldwin or Union Electronics Distributor for about $115 - $150

Just search under the parts for "Sony" "ballast" and the model number of your TV. Or just call them at their 1-800 number.

If you dont feel confident, you can have a shop repair it for about $450

try unplugging it from the electric wall outlet for an hour then plug back in, this should reset your tv back to factory default, you will have to adjust your setings if you changed them

Why is my picture more blue then red bulbs are working on RCA .....P46731AT

dear friend your tv has a defective fly-back transformer 99 times out of 100 that is your problem.
get the model number and call your local electronics parts distribuitor to see if they have it, if not call tritronics 1800-638-3328 they probably have it and is not too expensive.less than $25.00.now when you get here is the million dollar question can you do it yourself? if you can't call the repairman and by having the fly-back that will decrese the cost of the repair, is just the labor.


good luck

This is hte beginning of a convergence problem. If you can solder, try resoldering the pins on the convergence ICs. These are large black ICs attached to a heat sink and will be marked STKxxx. If that fails to resolve the problem, replace the ICs.

Keep us posted.

No , if fuse was blown you would not get the popping. How old is unit ? It sounds like your high volt splitter. common problem with rca. repair should not cost more than 250.00. you will want to have chassis number  and manu date for help

The loud pop was a capacitor blowing up or the high voltage transformer blew up. Very common problem.. if its the Transformer be expected to pay 250 or more to have repaired.

Was this the 220 ohm in the power supply??? and if the 5 amp blew right away then it probably took out the bridge rectifyer with the power surge that comes alog with hurricane damage to the power lines as I used to live in florida and repaired lots of sets damaged from storms!! After you check the bridge rectifyers I would start looking to find any other shorts. First measure across the ac line with the fuse replaced but not plugedf in . If its shorted check what I mentioned before if its good after you replace the shorted parts you maybe in luck. need more assistance go to sams photo facts download a schematic and we will trouble shoot this together if you post it here so i can look at it. good luck
