Hello :i have a bad projection tv Symptom :power


sounds like my 32", its going to be one of three things,
Convergence board,
if it is this you will need to order one online and install it yourself, lots of guides online to help you with this process,
High voltage power supply,
again this can be purchased online and directions are available, if it is the high voltage supply, the tv will act like it wants to come one and maybe click a couple of times
Low voltage supply,
the tv will do nothing, now if the tv does nothing, the low voltage supply isn't the only possibility, but the most likely, check fuses on this one as they are easy

My T.V. won't come on.


I would guess that the HV Block has failed. A very common failure. I would hesitate trying to replace it unless you are familiar with Projection HV circuits. You did good supplying
the Model # and Chassi #. both are required to get the proper part# if you try to get the part yourself or calling a service shop to fix it.
Hope this helps,

is this just a whine since you describe no problem with the picture it dosent jump or change color or flicker. there may be an easy fix this sounds like some coils oscillating and i tell you what can be done you can take some silcon and put on these coils to dampen then vibrations. now ther may be other problems but without looking this is my first gues ...where are these coils? ll037 on the power supply deflection board

Tv has sound ,no picture,power light comes on


Tihs would be the power supply unit gone bad.

1. Check power supply fuse if the fuse is blow so are the caps do not try to replace the fuse you will smoke this thing.
2. upon inspection you can remove the power supply unit and buy a new one. There about $150 bucks aftermarket for this unit. So I would be looking for other RCA's with this same series and pull some psu's to save money.

I hope this helps you find a solution for your TV these are nice to have and worth the repair.

Unit will not turn on.


CAREFULLY Measure the voltage on both sides of the fuse to make sure that the fuse is actually good.

No fix?

disconnect and reconnect the wires from the low voltage and control side of the power supply board.

No fix?

Throw it in the garbage.

Samsung hl-r5078w no picturead has a buzzing sound


that buzzing sound is likely the power supply letting you know it is overloaded. check the output voltages for 1 that is missing or low, it probibly has a shorted component on it.
