RCA 36 inch t.v. is on the fritz(any t.v. repairman out there?)
my 36" big screen t.v. is on the fritz!

it still has a picture tube and it is about 4 to 5 years old,when you turn it on everything works great for about 2 to 3 minutes and then none of the push buttons on the front work and the remote will not work.

you can't turn it off with the remote or the push buttons on the front panel,I do still have a good picture.

any ideas what could be wrong with it?

with all the new LCD and PLASMA t.v's coming out and lower in prices is it even worth having a repairman look at it?

I would love a larger flat screen t.v. but seems to be one of those years where everything is falling apart at home and on the cars!
thank's

Given that ALL works fine during the first few minutes, experience tells me that its an overheating transistor (within a chip) caused by a burned out resistor for sure. Also could be a solder failure.

UNDER no circumstance shall you attempt to make any repairs to it even if you "think" you can. There is an average of 50k volts waiting to be "discharged" CORRECTLY before doing anything else inside.

Hopefully someone in here might give you some other input as well.

Being that your TV is less than 5 years, it "might" be worth the investment to have it repaired, unless you are looking for an excuse to get an lcd or plasma.

The "might part depends on the model and cost of an exact replacement vs cost of repair. Most repairs are nothing but a swap of a removable circuit board. Knowing which one helps but getting a replacement is another story...once again read disclaimer(?) above

Then again...the analog signal will be turned off by 2009 if not mistaken, meaning all non-digital TV will become obsolete. I havent been to the FCC site lately...anyways...so time to upgrade?

The latest 1080i are pricey and the signal if not even out. So folks are paying top dollars now for a technology just around the corner.

Then there are those of us waiting for lcds and plasmas prices to be slashed when the next TV version comes out which are going to be laser driven...simply awesome.

Final thought...consider a smaller el cheapo brand smaller than 36 inch...say a 26 to 32?...in the CRT category. They are practically giving those away at practically the cost of your "potential" repair.

This way for about $150 NOW you hold on for another year when worth the investment into the what is available now...lcd and plasma...makes sense?

Best of luck!

Buy SONY
I had a RCA 32" too Did the same thing about six months ago, I took it in, it was repaired then worked for about two months, then the picture tube fried. (I just tossed it into the dumpster last weekend.)

I got smart and went back to SONY. It has been my experience that You cant beat them for reliability. I have had a 19" for 20 years that just keeps going. I bought a 36" to replace the RCA. Much better picture.

I'll keep buying low definition flat tubes until the cost goes up or the reliablity crashes.

You have an issue with the low voltage power supply in the television. This power supply is used to power up all of the controls. The power supply in question is either a 5volt or a 3.3 volt unit, depending on the make and model of the set. This voltage is typically regulated by a "standard" three terminal regulator (LM7805 for the 5 volt units), and is relatively cheap to repair if you have the right equipment.

Very true! It's low amperage though It won't necessarily kill you but it will hurt!....Ron

Loose solder connections
Can you bump the top of the tv and make the buttons work? RCA tv's are known for tons of loose (cold) soldered connections.

To my knowledge there are only two or three (max) manufacturers of CRT. To say buy this or that depends on personal experience and whether they got a good batch or not...it happens. After all. quality control is mainly driven by humans.

Example...I have a 26 JVC going on 10 plus years...living in florida...lighting capitol of the nation. I depend on ISOBAR Tripp Lite products to protect from such. So far still working and no repairs done to date.

Final thought...consider a subscription to Consumers Report...a good investment especially if looking into replacing other $$$ items within the next year.

you know what,I haven't the foggiest idea of the insides of a t.v.

I found a local rca repair shop that will check it out for $35.00 and let me know if it's worth fixing or not.

I really want a huge lcd flat screen but this year has been tough and money is very tight at the moment,I am already on pace to make $6,000 less than last year(too many mechanics at our honda dealer!)

maybe just roll the dice and try and get this one repaired for now and hopefully get a few more years out of it and then buy whatever is the latest and greatest at that time.

Failure of the low voltage power supply is not a common failure, neitheris a failure of the chip that is used to interface with the front panel and remote (Yes, both of these are controlled by a single chip). More than likely, the damage was caused by a power surge to the television, rather than from moisture.

If I were you, I would get it fixed and invest in a surge suppressor for the unit to prevent this from happening again. The repair should cost you about $100-$125

well they just called and said it is going to cost $139.00 for repairs.

they say it was the guide plus module that went bad.

I am picking it up saturday morning and will let you know how well it works.

That particular module also contains the control chip for the front panel and remote. Most repair shops will not repair a module, just replace it (the trained monkey effect). In the old days, we would repair the module, not replace it

I just had a similar problem repaired last week on a 32" JVC. I found a reliable local tv tech who repaired it. He said that the Internal computer had to be rebooted in laymans terms. It works fine and only cost me $53.00 and this was a house call!

I always seem to have bad luck!

the t.v. worked for about 4 hours and now it's doing the same thing.

I can't even take it back to the shop till at least saturday,I am in troy ohio for honda training.

and now if I take it back I will probably regret it because they will find another faulty part and it's going to nickle and dime me to death!!

now do I take it back in or just cut my losses at $139.00?

I used to have an RCA tv that had the same problem. The bad part about mine was right after the remote stopped working it would go to full volume and I'd have to unplug it to shut it off.

Had a repair guy come look at it and quoted me at almost $150 in parts. I decided to just get a new TV. I gave that TV to a friend that's good with electonics. Turns out it was only a couple wires that needed to be resoldered. He fixed it for about $0.25 of solder.

Does this place you brought it to warrenty their work? Obviously they charged you and didn't fix the right part. If they want to charge you more to fix it I'd personally get a new TV.

I would also stop payment on the check or CC if they don't fix it for you.

The repair person use the oldest method in the book for the repair .... the Easter Egg method (Replace parts until the unit seems to work). The remote and the front panel are both controlled by the same chip. If this chip burned up again, the low voltage power supply is faulty and needs to be repaired. High ripple on this supply will not affect the basic operation of the set once it is turned on, but can and will destroy the chip that controls the front panel interface. The low voltage power supply only feeds these circuits.

As far as the repair shop is concerned, they SHOULD warantee their repair. If they refuse, report them to the BBB and the manufacturer of your television if they are an authorized service agent.

well I called them and the lady apologized for the mishap and just told me to bring it back in and they would look at it for free.

the worst part has to be carrying the thing up the basement steps and back down the outside steps.

this place is an authorized rca repair shop and I told the lady on the phone that I understand due to the fact that I am a honda tech and yes these things do happen to us as well.

the worst part is every time I turn around something else is falling apart.

my wifes 95 dodge caravans transmision went bad just this week and the car is not worth repairing,so now tomorrow I have to find another van for her as she is driving my car.(and another payment to our stressed out budget)

sometimes you just have to stand back and laugh at yourself,I guess it could be worse but hey what the heck you gonna do?
