My TV - Same Model is blinking 8 times -

You mentioned a specific problem for the previous person's symptom, how did you know that is what was causing it? I saw another blog showing how to use the remote for self diagnostics - is that how you know?

If your FBT was bad you would not even get no flashes, set will only click , sony has a high voltage capacitor located next to hori output transistor small blue 1200pf 2,000 volts 2k most of them develop small pin hole causing set to shut down.Hori output could also be shorted.FBT is gray in color has 2 wires coming out of top of it red&black one lead goes to high voltage trippler other goes to focus&screen control block.

    OK one person had same problem blink 8 times replaced high voltage splitter block this is where 1 of wirers coming out of FBT goes to Part number is 8-598-955-32, how to tell if splitter block is bad remove lead coming from FBT make sure wirer is away from you and anything on chassis if high voltage comes up after disconnection from splitter it means splitter is bad.trippler/splitter same thing.

Tv wont power up after replacing 6 caps 4 bad 2 looked good but were in series so replaced with larger voltage. mitsubishi wd 62725


That model will usually have 8 caps that require replacement on the Power board and also 4 capacitors on the DM board which will usually cause the Non stop blinking light symptom.

I have seen the tube divider pack cause this too, Take the front speaker grill off remove the 4 screws and the panel comes off. There is a pack with 2 red 2 green and 2 blue adjustments, Try turning the BOTTOM red one down 1/32 a turn and see if the symptoms change

Television will not come on. The red light power button blinks three times and then nothing.


Not knowing your exact model, the following information may be a little off but will work all the same

I think you may have a few problems here. If you are comfortable with soldering, check the following parts first:
R7060 and R7066. These are .27 ohm resistors that feed the convergence ICs. They may be open. If they are open, the convergence ICs are probably bad and need to be replaced. These are STK390-110. These should be readily available on-line for about $20-$25 each.

Let me know if you need any further help and remember that working on a tv can be dangerous and can result in a large electrical shock.

JVC AV-56WP74 closes up and flickers when input is trying to come through


First possibility is a CRT coolant leak onto the signal PCB.
Examine from front and back with good light = even a few drops
of conductive coolant can cause various unusual symptoms....
Your symptoms are multiple and normally un-related, unless,
as you mentioned,all the signals converge......................T.
