When TV is switched on it works for a short time, then menues flash on screen and red light flashes continuously, the remote will not work now, the picture and sound have gone. Sometimes red light stops flashing and TV returns to normal but usually I must turn off power manually, leave for a few minutes and switch on again. The length of time for which it operates normally is getting shorter(10 mins). Sometimes when menu appears the picture and sound remain but not usually. Does this look like a serious problem. The TV is 4 years old. Hope you can help Diarmuid Byrne

The set may have shorted the horizontal out put transistor since it kept coming on sometimes. This could be cause by the driver transformer arcing causing a "spike" in voltage going to you horizoltal out put transistor. Stargazer

Hello, maybe there is a contact error in power supply or the deflection stage. If the resoldering does not help- here are some possible solutions: remedy Replace flyback location LP04. Entered for KV32S22 /SONY (Chassis) remedy 2 Replace IC351, Q602, Q601 (2SC4834M), R607 (1R/0.5W), R622 (10R), IC641 (SI3090CA) and Q502 (2SC5148). remedy 3 Replace tuner. remedy 4 Replace R607, Q502 and IC601. Entered for KV32S22 /SONY (Chassis) remedy 5 Replace regulator IC, R607, check C609, C610 (0.68pF) and C613 (0.0022pF/500V). remedy 6 Replace horizontal output transistor (2SC5148), IC601 (MX0841) and R607 (0.1R). remedy 7 Replace IC1701 and IC601. remedy 8 Replace Q501 (2SC5148), R607 and resolder horizontal driver transformer. remedy 9 Check and replace horizontal output transistor Q502 (2SC5148) and IC601 (MXD8411AB-F). remedy 10 Replace shorted R607. Also check T501 and Q501 for dry joints. remedy 11 Replace C608. remedy 12 Replace Q602 and D648. remedy 13 Replace Q502, Q601, Q602 and R602. Entered for KV32S22 /SONY (Chassis) remedy 14 Replace D626 (6.2V). remedy 15 Replace IC801 and R607. remedy 16 Replace horizontal output transistor and the associated damping capacitor. Check flyback transformer and SMD microprocessor as well. remedy 17 Replace R639 (4.7R/0.250W) located on G board in standby power circuit. remedy 18 Replace D600. remedy 19 Replace C502 (0.47uF/50V). remedy 20 Check D655(1N4937), D657 (1S1834) and Q601 (2SC4423). remedy 21 Check D606 for leakage. remedy 22 Check yoke between vertical and horizontal windings for S/C. remedy 23 Replace Q601 (2SC4834MNP), R607 (0.1R) and C517 (2.2uF/250V). remedy 24 Replace R611.

The most common problem (I have fixed lots) is the Vertical amplifier has developed a loose connection. It probably just needs resoldering. As things expand it makes and looses connection you picture goes in and out. The vertical chip is a large black chip that gets hot, over time it degrades the solder until a connection is damaged. Most newer sets have a protection circuit that senses the lack of height, and shuts down the picture tube to save it. When the picture dropped to a line on older TVs and left that way too long it would burn a line into the face of the picture tube. You then had to have the picture tube replaced along with the vertical amp. it's kinda like a screensaver for your TV.

A reset won't fix this. The standby light should be blinking a repeated count with a 3 second pause inbetween. Post that count here. That will indicate the circuit/condition that is preventing the set from turning on.
Thanks,
Dan

Press and hold the MUTE and SELECT buttons at the same time until the green light at the top of your remote flashes twice, then release both buttons.
Using the number buttons, enter the 5 digit code for your brand of TV. The green light under the TV should flash twice.
Aim the remote at your TV and press the VOLUME UP button. If the volume doesn't increase, repeat Steps 3-5, trying a different 5-digit code for your TV. If your remote control fails to program using all available codes, try scanning for additional codes. If one of the codes worked, proceed to the next step.
Press and hold MUTE and SELECT buttons until the green light at the top of your remote control flashes twice.
Enter 9-6-0 using the keypad on the remote control. The green light should flash twice again.
