Problems with RCA 27R410T 27

Hello:

I found this posting on FixYa...

(This 27" TV came in with the HOT (TL035) shorted, fuse OK. Replaced with 230760 (S2055N) and replaced the Flyback (LL005) 262341)

and it replicates exactly my TV's symptoms...

Rather than spend $150 or more at the TV shop, I'm game to try this fix.  Here's my question:  I'm quite comfortable around electronics and have done various repairs myself.  This would be my first foray into a TV... if I order the HOT and the flyback, will they be visibly obvious when I open the case and therefore easy to swap out?  I don't have any schematic or layout for the chassis.

Thanks

The flyback will be unmistakeable once (IF) you have the replacement and the HOT will be mounted on a heatsink very close to the flyback, sometimes on an apparent shield surrounding it.

Don't fail to buy some silicone grease or a silicone rubber pad for the transistor; these things are pretty close to death when everything is normal and will fail if you sneeze.

The RCA PN may be hard to find, messages I saw implied that but NTE has a substitute number for the S2055N:

This part should be available at most electronic suppliers and has an isolated housing making an insulator unnecessary but not some thermal help.

But the flyback . . .
That could be tough; my former supplier, who always had what I needed is gone and the market for replacement flybacks is shrinking daily due to the death of CRT monitors and TVs.

I have a 27 inches RCA TV (model:27R410T) , Firstable when i turn the tv on ,it works fine but just for about 2 minutes , after that video has gone , no video only audio ,and start changing channels...

It maybe some semiconductor IC got hot, need service or repair. It may repair itself if you leave it on standby for a month(at operating temprature a week)? This is low tempeature(the lower the temperature the longer the time) annealing or moisture curing technology, used by Nasa on transistor failure in satellites, or long range unmanned vehicles. You can always repair the unit later.

27R410T 27" TV: our RCA Model 27R410T has maybe 20 hrs of total us...

Ok, well the good news is prize or NOT it is still covered by a warranty, that's the law, you need to contact your local RCA office, and ask them for a referral to an Authorised service center, and you will be able to make a claim, and in any event, that's where you are going to have to take it to be repaired in any event. The Consumer Act, indicates that anything sold must be of "Merchantable" quality, clearly any unit that fails after less than 24 hours use, falls into that definition. You simply have to find a Dealer, Service center, whatever, and in all fairness, they should take care of it, there may be some costs involved, but usually not. Below is a technical Service manual, this is what I use to train the engineers to repair these units, have a look, www.electro-tech-online.com/.../36401d1261034747-rca-32-television-32v434t-need-help-repairing-atc010_training_manual-1-.pdf

27r410t no power

did you check that you are receiving a good hot (a consistent 110 ac) check the tv on a different outlet otherwise the chassis board has malfunctioned inside the tv. Probaly the flyback transformer which converts the 110 ac to thousands of volts to power the CRT (picture tube) which has failed more than likely. Usually the culprit after sustaining a surge from a lightning strike. Not worth the repair just replace go to your local pawn shop for a great deal on another used tv
