Re-soldering the flyback transformer now I get no picture

Hi:

I tried your advice to re-solder the flyback transformer (all 10 pins)...but now I get no picture at all.

I can run VCR and other components and get a good picture. However, trying to run my cable box now...all I get is snow...

Any advice?

Check to see if you have it on the correct input with cable connector channel up or down. the fact that you have picture on other inputs tells me the signals not getting through somewhere. and it possible its not being routed correctly. so try changing inputs on remote also try searching for channels with cable plug up to it. Physicaly there may be a tuner issue.

My mom has a RCA HD61W66 and the picture was showing red, blue and green "lines and shadows" as if the picture was warped. It has now stopped showing a picture at all but the power is working....


The flyback transformer has solder cracks around the pins and most likely blown the FL231 Micro fuse to the right of the flyback.I would inspect the flybacks solder. The FL231 and the CL230 and DL231 should also be replaced ( near the flyback) You can get the ITC222 Convergence option missing repair kit from www.tvrepairworld.com under the RCA repair kits. The kit contains the parts and the CD with repair instructions

I ALSO HAVE A 52 INCH RCA (2 YEARS OLD) I HAVE TRIED ALL OF THE TIPS THAT HAVE BEEN DISCUSSED. LUCKILY I PURCHASED THE EXTENDED WARRANTY ON THIS UNIT.. AFTER A MONTH OF OVER THE PHONE TROUBLE SHOOTING FROM WARRANTY REPAIR CENTER THIS INCLUDED REMOVING THE BATTERIES IN CASE THE REMOTE WAS BAD. THEY FINALLY CAME AFTER IT YESTERDAY. THE PICKUP BOYS SAID THAT THEY ARE HAVING A LOT OF TROUBLE WITH THESE UNITS DOING THIS SAME THING. THEY ALSO SAID THAT SOME WERE BEING REPLACED WITH NEW ONES. NOT SURE IF RCA OR WARRANTY IS REPLACING (MINE WAS PURCHASED FROM BESTBUY WITH BEST BUY WARRANTY). IF ANYONE HAS SPOKEN TO ANYONE ABOUT A REPLACEMENT PLEASE RESPOND. I THINK IF THERE ARE SOME UNITS BEING REPLACED WITH NEW ONES WE ARE MORE THAN LIKELY GETTING THE SAME DEFECTIVE UNITS (WHICH WILL MORE THAN LIKELY WORK UNTIL OUT OF WARRANTY). I WISH THEY WOULD JUST GIVE REFUNDS OR CERTIFICATES TOWARDS NEW DIFFERENT UNITS MAYBE IF THERE WERE ENOUGH COMPLAINTS THIS MIGHT BE CONSIDERED.

I have a Panasonic CT-36hL43G TV that just turned offf while watching it and now the led by the power button blinks one time. Can anyone tell me what this code means or what the problem might be?


i hope your tv is more than 4years old ....... in all CRT TV's or CRT monitors after 4years a component called flyback transformer (see picture ) becomes weak - its work is to supply voltage to tube............. then following are the signs ...
(1) in some TV's only front LED's blinks - no picture no sound.... (2) in some TV's picture comes slowly after few seconds or after few mins or after few hours......... (3) in some TV's suddenly picture & sound goes temporarly & after some time again it appears ...... etc in case of (2) & (3) only flyback transformer needs to be replaced .....100% GUARANTEE again TV works normallyBUT in case of (1)... --------------- YOUR CASE (a) either only flyback transformer gets deffective or (b) flyback transformer & another component called transister ( will be near flyback transformer & its back portion is attached to aluminium metal ) gets defective or (c) along with flyback & transistor -- 3 or 4 more components (resistors, diodes, some times ICs ) gets deffective so replacing flyback transistor is a must .. & to find whether any other component is deffective or not completemainboard has to be checked ....... so if you are a technical person & having expierence in servicing line then you can do it yourself otherwise approach good tv service engineer ........... your TV is really very good one ... so don't think of buying new TV .... just goahead for repairing it it is worth & it works for atleast 2 more yrs....... try this & tell me what happened switch off your TV ... remove power cord from socket ,,,,.ware some mat or chapples to your feet ..... remove your TV's back side cover ......... observe carefully for any physically damaged components .... if you find then don't do anything ... close tv cover & approach tv service engineer ............. but if no physically damaged components are visible then take a suitable screew driver & rotate 2 (or 3) Knobs on flyback transformer in clockwise or anticlockwise direction - very little ( 4 or 5 degrees ) - you have to do this without touching any cable or any part of your tv .......... then fix..... back side TV cover ........connect power cord - stay at a distance & switch on your tv ......... if you get picture atleast for few seconds then in your case only flyback transformer needs to be replaced otherwise complete mainboard has to be checked. to find other deffective component ............. so your tv problem is a harware problem - it cannot be solved using remote control or any buttons on your tv ..... if you are finding difficult to get it repaired then you can remove your tv mainboard with the help of some technician & send to me ...... i will replace deffective components .... & send back to you ....you only have to bare the shipping charges .....it will take maximum 12days (5days - to recieve + 2 days servicing + 5 days to send back to you )....

No ruster but have sound


You have bad grounds on the power supply board. The power supply will have the flyback transformer. You must pull this board out and really, really look for bad solder grounds. Check for cracked or separated pins on transistors,resistors, capacitors,diodes, jumpers and transformers (on the solder side of the board). Resolder as necessary. Be sure to check grounds on the vertical IC, you do not want to short the pins together with excess solder. I'm sure you can fix this TV. It takes patience and a very good eye,...eyes! This is good advice. I do not believe you will need to replace parts. Thanks for asking and show all hands of support!

Picture goes into horizontal lines while watching then you shut it off for 10 min. or so and it resets it self


solder connections in horiz.drive/output circuit.also solder the flyback transformer.if only 10 minutes you need to solder in the
horiz.circuit area.get a magnify glass and usually will see hair line cracks around the
components.

I have a RCA HD 52in and I'm have a problem with the Convergence Ic's


Hi, rca`s don`t have convergence IC`s, they use an entirely different system to perform convergence, you have a blown chemical fuse and 3-6 bad solder joints on your flyback transformer. replace fl231 chemical fuse rated at 400ma. right beside flyback (theres 3 of them your bad one is the middle one)and while your soldering re-solder all of the flyback transformer pins and your tv will be back to normal :) video-tek

The picture has sucked in and kind of looks like a bow tie and the colors are out of alignment


very common problem on this unit. on the deflection module next to the flyback transformer, ther are 3-boxlike(square) solder in fuses. the middle one is 400ma (less then 1/2 amp) and will read open. replace with 1/2amp pico fuse and solder all pins on flyback transformer, as this is the cause of the fuse opening and the convergence to fail leaving bowed-in concaved pix. dime to a dollar that'll "FIX-YA" up. :) mch
