SOURCE: Blows fuses

I found a post where someone replaced several capacitors with ones he described as titanium and a higher voltage like 100 v rating rather than 50 as oem. He states no more problems. I found this site while searching again. I also found a free download pdf repair manual from JBL - site defined as Harmon, and they show revised parts replacements for these caps - 100 volt. I just bought a used one and not hooked up as yet, but I plan to use slow blow fuses and possibly a little higher rating - not much though, and I believe there is a ceramic type - color solid white - that may withstand the apparant surge. Theres also a recent post somewhere for sale of the amplifer board... 64smi or something like that. Hope this helps. Ken

SOURCE: blown fuse

Most likely there was a power event (surge, brownout, ect) that caused the power supply to fail in the TV causing the fuse to blow. you will need to have someone come and look at the unit and give you an estimate. If you keep putting fuses in and blowing them you could actually be causing more damage.

32 inch rca getting power, but wont turn on


I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.5_29_2012_3_02_02_pm.jpg
left one is good and right one is bad.

RCA 32'' TV making a humming noise


sounds like a shorted horizontal output transistor probably caused by the high voltage transformer or hot. it is most likely fixable but it will be costly.

My rca d52w14 52 inch will not come on


if you have a multitester handy, measure the resistance across your tv plug as you press the main switch, if you get infinite resistance, check for fuses. you have to open it up, if you are nor sure you can do it, visit your local service center

Won't work


It sounds like something in the high voltage (flyback) circuit failed. If any little thing shorts in these RCA's they will not start up. Stargazer
