Have sound but no picture

Sounds like the flyback transformer. You can get a replacement flyback from www.tvrepairworld.com and assistance to help you identify if the flyback is the issue

Discharged Flyback Transformer. Removed main pc board from bottom of TV and flipped over, no apparent damaged components or blown board traces were found. Noticed a lot of flux in various areas on the board that seemed unusual (maybe TV was worked on before as I bought a showroom demo at Circuit City). Used a plastic screwdriver to remove all flux between connections on ICs, Transformers, Flyback Transformer, and various other components. Cleaned all debris, dust and crud accumulation (TV is over 10 years old and there was alot around the Flyback Transformer) from both sides of board using a lightweight paint brush.
Used a magnifying glass to check all solder joints for possible cold solders and found none. Did the same for Power Supply Board. Checked various ICs and Power Transistors for opens or shorts (in machine) and they seemed fine. Reinstalled boards, said a few Hail Mary's and fired it up.

The protector Led no longer flashed under power and lo and behold I got picture and sound!

I cleaned the lens on the projectors (again 10 years of dust accumulation) did a magic focus adjustment and it works fine!

After reading other fixes, I fully expected it to die after 10 minutes so I left it on all day and against all odds it still works.

What was the fix......Dirt buildup on and around Flyback and other components,,,,,,Flux conducting electricity between contacts on Flyback and other components.....or oxidation on connectors between Power Supply and Main Board.....I don't know.... all I know is that for the moment I saved around $ 300 - 400 in repair bills by doing it myself.

i have hitachi 53" tv and model number 53sbx59b.
tv flyback gone so i need a flyback and i want to know the price for that

could be blown flyback transformer

can you identify the flashing item because it sounds like the flyback or the high voltage splitter can you send me a picture of the part thats flashing white please?

can you see the g2 from crt sound like you list your g2 from
the flyback.i need m# plz

Usually the horizontal output does become shorted when the flyback goes. I would replace the H output as it only cost around 3 dollars. You can check it with an ohms meter out of circuit to determine if it is indeed shorted or open.

I would suggest check the the secondary side of the power supply for around 130VDC if that voltage is found to be lower than 120VDC I would suggest to replace CP80 with a 100 mfd@250 vdc. Part # 218374
Check Globalsemi.com for these parts.

if you are hearing a click and electrical statics when you try to turn it ON, the flyback of the tv is busted there are alot of reasons for that problem lighting is one so dont leave the cable screwed in if ever youre going out for a long time. you can have it replaced by a technician ( flyback). but it would cost you. and im not sure if you can find an orginal flyback considering its 10years old. there are replacement flybacks but quality would not be as good as the original one.

I had this with a rca once. Can you hear a crackeling noise coming from the flyback transformer? My problem was just the wire was loose
