I got the thing to work by changing out the u7 chip on the main board. Now here's the wired thing. When you first turn it on it will work fine for about 30 minutes. Then it will loose video but keep the backlight. You have to unplug it to turn it off. After its been on and looses video you can plug it in 5 minutes later and i t will work for about a minute then loose video again. U33 voltage if fine during all this. U7. Is outputing 1.5 volts when its working but when it loosed video it drops to 1.1 volts but the backlight stays on. I am going to replace u7 but want to know of there is anything else I should look at?

Re: new problem, new thread. vw42l
Perhaps the video processor is freezing up. Try checking the video processing board for bad caps, and check the voltage regulators on the board too. Did you figure out what u7 powers? Does it get very hot?Muh-soggy-kneeComment

Too late now but you should have kept on with the old thread - I havent the time to jump from one to the other can you copy the any pictures forward. Is the U7 fed by another regulator - check that when the set is working & non working.Please upload pictures using attachment function when ask for help on the repair

by SpikemanHi, I'll tell you the story of this PC.
The PC was repaired because it had a shorted power supply. What happened was that the plastic covering the buffer battery positioned by the manufacturer on the capacitor melted, thus generating a short.
After the repair, the PC worked, I installed Windows 11 and I may have had some problems with the video drivers, but after a bit of tinkering I think I solved them.
However, the PC later presented the problem in the video shared very frequently.
The problem also occurs at startup, in the bios and when using it as a monitor thanks...-

by hugocarmoHi everyone.
I have the following problem.
I have a Grundig GV-250 VCR which has not been used for over 10 years. When I turned it on, the fuse of the PSU burned out, after being replaced it burned again, I ended up verifying that I had the bridge rectifier and the mosfet in short, I ended up replacing it, and I replaced all the electrolytics of the PSU. However, it started to behave strangely, as I will show you in the video that I will attach as a link.
In short, I ended up replacing all the ICs on the power supply CNY17G, TDA4605, TL431, TDA8137, TL082CP, AN3824K, L2720,... -
