RCA D32F750T TV

I have recently replaced the flyback transformer for my RCA D32F750T TV with a compatible acme flyback. The picture is now dim, the colors are off, and text is blurry. All "menu" adjustments do not correct these faults and are unreadable. I was wondering what this could be, since I am more or less an amateur, and whether or not using rosin solder instead of silver solder when attaching the new flyback would cause this result.

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.

Sitting here watch tv and suddenly the picture went warped and discolored. Picture looks like the colors are seperated. blue green and red.

Your TV has convergence chips that need to be replaced by a tech. These keep tour red green and blue lights in sync with one another in order to give you a sharp color picture. When they fail your colors seperate.

Picture blurry

What was replaced by the repair shop? The blurriness may be out of focus. If so, the focus is controled by the flyback transformer. That connects to the picture tube at the top (anode cap).

RCA pix tearing horizontal lines

Get an ESR meter and check all the electrolytic capacitors in the set! I am sure you will find many decoupler and coupling capacitors that are on the edge or too high in ESR.

RCA F27442tx51 dead but making high pitch noise

Update on finding replacement tripler (Flyback Transformer) for RCA F27442tx51. This is a follow up on my report dated Jan 12 2008. Further investigation revealed the Horizontal drive transistor was also blown. It is a 2SD2578. Internet search turned up ACME ENTERPRISES in Orlando Florida. www.acme-slaes.net. Surprisingly they also sell Flyback Transformers as well as other TV repair parts. The cross reference for the needed Flyback is ACME-2236 FBK. The part number for the transistor is 2SD2578 SANYO TRANSISTOR. The price for the transistor is $2.69. The Flyback is $22.95. Shipping to CA is $6.75 and handling is $1.99. Two days after ordering, the parts were at my front door. The set works now except the picture still goes off after 5 minutes or so and then comes back on, sound still works during the dark period. The original symptoms before it blew out in the middle of the night and started chirping. I now have the set on the bench attempting to find the intermittent part. Stay tuned I'm on the hunt.

RCA D32F750T won't turn on

Well, I glad to know that fixing this set is unfruitful.
Yes, I am yet another unsatisfied customer with the same complaints.

Ha, my TV made some kind of weird noise and I saw a flash behind the set.
After pulling a back panel, because it only comes with a 1 year warrantee,
I saw the burned part.

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.
