TV WILL NOT COME ON - TV Chirps when you plug it in

I bought this TV and late one night it went OUT. The picture had been intermittent before the TV "died". I have heard that the problem is with the power supply on the circuit board. How do I fix? Yhanks, JImBO

Re: TV WILL NOT COME ON - TV Chirps when you plug it in

Would it be cheaper to just buy a new TV (mine is 7 years old and is chirping) rather than pay a tech?

Re: TV WILL NOT COME ON - TV Chirps when you plug it in

The F25432 uses the CTC203 series chassis. The most common cause of the picture being intermittent is poor solder joints on the small coil connected to the base of the horizontal output transistor. These cracked solder joints will eventually cause the horizontal output transistor to short, and the power supply will "squeel" when plugged in. If you have experience working on TV's then you can try resoldering the joints on that coil and checking/replacing the horizontal output transistor. If you do not have experience working on TV's then allow a qualified tech to handle it for you.

Hi my name is jeremy snow and i have recently had problems with my sony trinitron xbr 1997. lately the picture like scrunches up into the top of the screen and the tv just goes black and now like sometimes...

You have two problems. Dry joints causing the no picture and capacitors causing the frame cramping.
A 680uF 35Volt capacitor will fix the frame cramping and re soldering underneath almost everywhere will solve the intermittant picture fault.

Sony FD Trinitron Wega model KV-34BR800

Sony Wega Triniton KV-32FS100 TV

For the last week my TV has been going to a black screen for 10 seconds or so then the picture returns. It has been continual. Last night it stopped going to black screen, but now the standby light flashes 5 consecutive times and the color went haywire. A lot of red and everything that is suppose to be black is green.

I did a soft and hard reset with no success. What's wrong and is it worth fixing? Bought new in November 2002.

Power button Flashes

For the first one, please list the model number and count the blinks. Also, can you please post each problem separately. It will get too confusing trying to address 3 sets with different but similar problems.

No Picture

Rarely picture tube also shows the same symptom. High pitch sound is due to through deflection area LOT power supply is loaded. Compulsary horizontal output transister short. From your statement i think Lot puncture takes place. Change LOT and horizontal output transister and check tv is now working.
