Replaced Flyback Transformer and now the colors are screwy

I recently replaced the Flyback Transformer on the TV and when I powered everything back on the colors are wrong. It's difficult for me to tell what exactly is happening, but it seems to be either missing one of the colors or confusing them. There was a problem when removing the old transformer one of the solder leads lifted off the PCB, though from looking closely at the board it doesn't seem to be connected anywhere unless the board has multiple layers. Does anyone know how to get a hold of the schematic for the the TV so that I could try to run a wire from the affected pin to the next component in line? Or anyone have any other suggestions on what to look for to solve the color issues? Thank you very much.

Re: Replaced Flyback Transformer and now the colors are...

When you replace the flyback do you have to solder it or does it just plug into the board

It is possible that the degaussing thermistor fell out while you wer changing the IHVT. RCA is famous for the bi-metalic thermistor falling out or just one wire becoming disconnected. look next to the fuse and see if there is two wires sticking up with nothing connnected to them. If this is so, look inside the tv for the thermistor. You can actually repair it by burnishng both sides with a small file and then adding solder carefully while out of the tv, then brazing both leads to the thermistor. Also make sure if the chasis is a ctc203 that the inductor connecting the base is resoldered. This is the main cause of the shorted H. out and the shorting of the Ihvt. Always re-solder all suspect connections. 80% of all newer tv's problems are the result of poor solder connections. Since the formula was changed %lead to tin many companies have had numerous problems with wave soldering.Scrivitron

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 only have to bare the shipping charges will take maximum 12days (5days - to recieve + 2 days servicing + 5 days to send back to you )....

My tv cant turn on

make sure the c5299 s not shorted again. and if it is not i suspect your flyback transformer is bad . check for cold solder joints on voltage regulator and board.

It won't turn on

The smell of something burning is not a good sign. The clicking sound you are hearing could be a relay or breaker kicking in and out as a result of whatever is wrong.

This could be cause by:
1. A problem in the power supply.
2. A problem with the Horizontal Output Stage.
3. The Flyback transformer.

Someone gave me a TV once that had the same problem. I determined that it had a bad flyback transformer. I replaced the transformer and the TV worked about 5 secs before I saw some black smoke come out of the new flyback. I turned it off right away and realized that something else was bad that caused the original flyback to burn up. The same thing was causing the new flyback to go as well. It turned out to be a shorted, 50 cent hi-speed switching diode. Fortunately, because I had turned the set off quickly when the 2nd flyback started to smoke, once I replaced the diode, the TV was fixed.

If you want to get it working again, you'll need to have it serviced.

Good luck,
- Jim

No power.

Usually, in those Sony sets, a crack developes on a small transformer in the horizontal drive circuit, which causes the horizontal output transistor to short. This immediately shorts out the switching transistors in the power supply and blows the Sony 0.1 ohm resistor fuse. A shorted flyback (high voltage) transformer will also have the same result. The power supply does NOT need to be replaced. The parts should be replaced, the flyback checked and the board resoldered by a qualified tech familiar with Sony sets.

Did you adjust the two controls on the new flyback? The top one is almost always the focus control and the bottom is the G2/screen control (brightness) If you adjust the G2 do it until the picture looks normal, too high and you will get retrace lines through the picture.

No picture, sound ok.

When you change the flyback and the HOT you are supose to replace a small capacitor that came with the flyback and also the small coil l401 that connects the hot base to the horiz. driver transformer secondary is supose to be taken out, the leads scrapped off of insulation and resoldered into place.
