Having problems with your Standard (CRT) Televisions ?

I have a sony trinitron kv36fs210, no sound no picture, stand by light blinks 5 times, tried unpluging for 24 hours, same problem. google searched problem,results found akb circuit problem, im not a tv repairman but will give it a try, but need some help, thanks. rick



Answers :

Actually the code five (standby blinking 5 times) is an error in the AKB (auto kine bias) circuitry. This could be caused by a bad picture tube or the circuitry itself has something wrong. If the AKB circuit can't adjust the picture tube then, in most cases, it will shut down the TV.

I have this same issue with my Sony KV-32FS13 TV except the TV never shuts down. I am still searching for major clues on how to tell what part is bad. I will get back to you if I find something.
It seems to be a problem to the power supply unit. I would suggest you have a look at the circuit board and look for capacitors that could have a popped up head. If you notice any, replacing it would solve your problem. I had the exact issue with my tv and fixed it that way. If you have any question please do not hesitate to ask, good luck.

I am having the same problem with my 3 yr old 52 inch Bravia HD LCD TV. The right side of screen starts out darker than the left side and then in about 5 minutes it brightens on the right and has horizontal lines for another 10 minutes. Then suddenly the whole screen pops on and the picture is fine. Is this a simple fix or an expensive one? I'm very disappointed as we paid big $$ for this set from Circuit City. Sony should be backing up their product with this problem. I have posts all ove

Problem with TH-C50FD18:Gives off 2 blinks I replaced the D-board and the A-board to no avail. The power trips the moment the 15Volts ON occurs to send 15volt power to SS, D-board, A-board and SC-board. I found no short on this 15Volts line that is switched by the MC701 Power MICOM Processor. It looks like a 15Volt error is detected, nonetheless.That's why it always reverts to standby mode. Could this be a 15volts power regulation problem?

We own a Sony FWD-50PX2 television. A few weeks ago it would not turn on. The power is going to the television. When you try to turn the tv on you can hear it pop and the red light showing it is off will flip to green and then turn back to red. We would like to just repair the TV as it is a very nice television set. We thought possible power supply, but it is trying to turn on. Any help you can give to help correct the problem would be great.

Dear welcomejee, I have a Sony Grand Wega 60" LCD, owned since June 2004. Model # KF-60WE610; Date of manufacture- April 2004. Recently while watching TV, the screen turned black. No picture. No sound. Presuming it may be the XL-2100U lamp, I took apart the TV to check and found that the filament inside the lamp had exploded. Thus, I ordered a new lamp. But, here's my main question. If in fact the problem is the lamp, then why would the sound NOT work? Or is there a safety cutoff on

I have a mitsubishi 55711 diamond series that the green light flashes. I replaced the 7 capacitors on the DM board per reading typical concerns and still same issue. I found the 125v 4a slow burn to be open circuit w/no continuity going through it. I dropped a bead of solder across and it popped 3 of the capacitors in about 5 seconds. is this a load bearing fuse or should i say a resistor of sorts or did it pop originally from something else in the tv and the capacitors was not the problem to st
