Question about RCA F35670MB 35" TV

TV won't power up and blows the fuse

Tv worked great (fantastic picture as usual) one night and the next morning it was completely dead. No power. We took the back off and found the fuse and replaced it. As soon as we plug into power source the fuse blows (green light flashes). Any ideas what it could be? Worth repairing a 10 year old tv? The television is very heavy and I'm only going to move it once. Thanks.

Re: TV won't power up and blows the fuse

A 10 year old RCa most likly has a bad Horizontal output transistor as well as the main High Voltage transformer and The transformer is no lonmger available from RCA. The replacement wont last longer then a year if your lucky. My advice on a set this old ?? Buy a newer one!!

No picture.

Your set may be fried, or at least the power supply or fuse(s). If you feel like you could work on it, open up the power supply (if it's outside of the TV) or open the set itself (if it's an internal power supply). Look for the fuse(s) (the little glass tubes) and pull them out and check them one at a time (in case they're different values and you forget which one went where). If any of them have a broken filament (the little wire inside of them), especially if they have any black soot or brown-ish stuff in them, then the fuse is blown and needs to be replaced with an identical value fuse.
DO NOT REPLACE FUSES WITH DIFFERENT VALUE ONES. I can never stress that enough. On the metal band, it says the current it allows. Match it up with another fuse (it'll be the same size and everything) and bam, that could fix your problem.
If it's not a fuse, then perhaps the filter capacitors in the power supply are shot. If you don't know what they look like; they're cylinders that are usually placed right by where the cord comes into the supply. If any of them have a hole or any black or brown residue around the bottoms, then they're blown and need to be replaced with identical ones (or at least the same capacitance and max voltage). Be careful with capacitors. If they're put in the wrong way, are shorting out against anything else, or have a max voltage that's too low, they can blow immediately and sometimes violently. I've seen them blow out and have electricity arcing across them, frying everything around it.

is hv circuit problem a power transistor to 25KV transformer maybe dead, check the HV Circuit, or 1XXV output from Mains transformer the fuse maybe dead

Turned it off last night was working great, this morning we cannot get any power at all, everything else is working around the same plugin

These sets have quit a complicated power supply and that is usually how they go. Everything is all good at turn off and then stop at next turn on. It could also be a horizontal/high voltage issue. It is hard to say as there are many probable causes. Thanks

No picture, sound ok

Rca has been known to have bad solder joints in the deflection circuits. Usually around the flyback and transformers.. check it over real good. Just be careful as you can still get shocked after the powers removed the capacitors and picture tube will hold a charge in them.

Tv no sound no pictures power light blinking

There are a couple of things you could check on this one if you have the equipment and are somewhat skilled in electronics.
Take a test meter if you have one, if not try the local radio shack. Unplug the set and remove the back. Locate F802 a small pico fuse in the SMPS 4a/125v. Test this for open - if open replace it...
Next locate Q472 ( 2SC1740 ) a common NPN amp transistor which will cross to NTE85 in a pinch. This transistor is in the shutdown circuit and if it's failed usually causes the conditions you have there..
Try at least these, and if anything here sounds the slightest complicated take it to a shop - it should be a rather inexpensive repair...

No picture, sound and/or stanby indicator light...dead!

Loss of low voltage supply has happened. This regulates the ability of the set to sense the remote as well as the front panel switches. Could be anything from open T1 secondary to a regulation problem; i.e. excess drop from defective component....accordianman
