There is either a video driver/output fault, (found on the pcboard that the tube plugs on to and is usually an IC) or you have a short circuit grid to cathode on the red tube.
Replacing the IC is no problem but to replace the tube means a lot of work and money.
If it is the tube and the TV is getting on a bit, time for a replacement? The cost of a decent LCD screen will be less than the repair cost with a tube.

Hi i have a JVC GD-V4210 PCE it has power but it has no picture or the fans has no power the led goes green when turned on then goes flashing red please could someone help


Your TV power supply board is damage and will soon cause your TV to not power on. Yes, cleaning the fan will only temporary fix the situation but eventually you will need to fix the power supply board. You can order one on ebay or amazon but make sure to have the correct serial/model number on the back of the TV before ordering and fixing it yourself. However, if you are not sure then have a certified tech to come see it.

Stuck in standby


Sorry about that. When the tv goes bad like not turning on, the green light will blink, and goes right back to red standby light while the dtv letters will briefly show on the lower right of the tv screen, then go back to blank screen. The tv will need to be taken to an authorized service center for repair. Common causes are a bad inverter/power supply, power control board, or circuit board.

Please help!!! Problem with JVC DLP TV


You need to replace the power supply board. The new ones have a bigger heat sink - obviously JVC knows about the problem because they made the new ones bigger. It cost $250 from JVC and I installed it myself - took about 3 hours to do. If you are not tech savvy call a repairman. Hope this helps.

Red screen on Hitachi 50V500


Any time the screen is all red it's typically two problems from my experience in this technology:

1] you might have the input of a component connected incorrectly. Check the connections, fix it if you need to. If certain colors do not match up or are hooked up properly with the component or composite or other connections it can create a red, gray, or green screen from it.

If that does not work...then...

2] Unplug your set then plug it back in entirely [power input]to make sure that will not create a simple fix. If that is not the case for those above it can typically be a mother board going bad. Some times it can be affordable some times costly. I'd recommend contacting the manufacturer even if its out of the warranty period they are mostly okay with helping you over the phone to find a local repair auth. center used to working on this type of technology since not every service center knows how to.

Let me know how things go. I do wish you the best of luck and eager to hear back from you on how things work out with these two things. Any red screen is bad, just as the old saying when you are out in the wilderness goes, "eat red--your dead" that is very true for most TV sets as a sign it's heading out....

Red CRT is dim....


Yes I did. You will need to get a service manual for this TV set to trace the voltage coming from the sweep power supply. If this is a problem that is new after you replaced the convergenbce4 board, you for sure have a broken wire or connection somewhere in the set. Have seen this happen may many times after a novice repairs a TV set. Good Luck
